Diagram Ref No 15

The exterior temperature sensor is positioned where it can monitor outside air temperature while minimising the influence of heat generated by the engine and other vehicle components. Its readings can be used to provide the driver with an outside temperature indication and, depending on the vehicle specification, may also be referenced by other temperature-dependent systems.

Over time, exposure to water, road dirt, temperature extremes and vibration can cause the sensor or its electrical connections to deteriorate. A faulty sensor may display an incorrect outside temperature, produce intermittent readings or stop providing temperature information altogether.

This OE Match Exterior Temperature Sensor provides a high-quality replacement for a failed, damaged or inaccurate original sensor, helping restore dependable ambient temperature measurement.
What This Product Does:

• Measures ambient temperature outside the vehicle.
• Converts outside temperature into an electrical signal.
• Provides temperature information to the relevant vehicle system
• Supports accurate outside temperature display where fitted.
• Helps the driver monitor changing external conditions.
• May provide temperature information to associated vehicle systems where applicable.
• Responds to changes in surrounding air temperature.
• Replaces an inaccurate, damaged or failed exterior temperature sensor.
• Helps eliminate implausible or intermittent outside temperature readings.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Outside temperature display showing an obviously incorrect reading.
• Temperature displayed significantly higher or lower than actual conditions.
• Exterior temperature reading stuck at one value.
• Display failing to respond as outside temperature changes.
• Intermittent or fluctuating temperature readings.
• Outside temperature display disappearing completely.
• Implausibly high or low readings.
• Temperature-related warning behaving incorrectly where applicable.
• Sensor-related diagnostic fault codes.
• Visible damage to the sensor.
• Corroded or contaminated electrical connections.
• Broken or damaged sensor wiring.
• Physical damage caused by road debris or previous repairs.  

Why Replacement Matters:

• An exterior temperature sensor provides useful information about the conditions surrounding the vehicle. An inaccurate sensor can make the displayed temperature misleading and reduce the driver's ability to recognise potentially cold or changing road conditions.
• Where the vehicle provides a low-temperature or frost warning, an incorrect sensor reading may cause the warning to appear at the wrong time or prevent it from operating as expected.
• Depending on vehicle specification, ambient temperature information may also be referenced by other electronic systems. An implausible sensor signal can therefore potentially affect functions beyond the temperature display itself.
• Sensor problems are often caused by age, corrosion or physical damage. Because the sensor is exposed to external conditions, its wiring and connector can also deteriorate over time.
• Replacing a defective component with this OE Match Exterior Temperature Sensor helps restore accurate ambient temperature information and dependable operation of systems that use the exterior temperature signal.

Crankshaft Position Sensor, Cylinder 6-10.

Restore accurate engine speed and crankshaft position monitoring with this OE Match Crankshaft Position Sensor, specified for the cylinders 6–10 application on compatible Porsche engines.

Fits:

Diagram Ref No 40

The crankshaft position sensor is a critical engine-management component. It monitors the rotational position and speed of the crankshaft and sends this information to the engine control unit (ECU). The ECU uses this signal to coordinate essential functions such as ignition timing and fuel injection.

Accurate crankshaft position information allows the engine management system to determine precisely where the engine is within its operating cycle. If the sensor signal becomes weak, intermittent or disappears completely, the ECU may be unable to control ignition and injection correctly. This can lead to difficult starting, misfires, poor running or a complete no-start condition.

Electrical sensors can deteriorate through age, repeated heat cycles, vibration, damaged wiring or connector problems. Some failures can also be temperature-related, with the sensor working correctly when cold but becoming unreliable once the engine reaches operating temperature.

This OE Match Crankshaft Position Sensor provides a high-quality replacement for a faulty or damaged sensor, helping restore accurate engine timing information and dependable engine-management operation.
What This Product Does:

• Monitors crankshaft rotational position.
• Measures crankshaft speed or engine RPM.
• Sends crankshaft position information to the ECU.
• Helps the ECU determine correct engine timing.
• Supports accurate ignition control.
• Supports correctly timed fuel injection.
• Helps maintain smooth and consistent engine operation.
• Provides essential information during engine starting.
• Supports accurate engine-management diagnostics.
• Helps maintain reliable performance across changing engine speeds and loads.
• Replaces an intermittent, damaged or failed sensor.
• Is specified for the applicable cylinders 6–10 position/application.  
  

Symptoms Of Wear Or Failure:

• Engine cranks but does not start.
• Intermittent starting problems.
• Extended cranking before the engine starts.
• Engine unexpectedly cutting out.
• Engine stalling when hot.
• Engine restarting after it has cooled down.
• Intermittent loss of engine power.
• Rough or inconsistent engine operation.
• Engine misfires.
• Hesitation during acceleration.
• Check engine or engine-management warning light.
• Crankshaft position sensor-related diagnostic fault codes.
• Engine speed signal disappearing during diagnostic testing.
• Tachometer or RPM information behaving abnormally where applicable.
• Damaged sensor wiring or electrical connector.
• Heat-related intermittent sensor failure.  

Why Replacement Matters:

• A sensor that fails completely can potentially prevent the engine from starting. An intermittent sensor can be more difficult to diagnose because the vehicle may operate normally before suddenly stalling or refusing to restart.
• Heat-related deterioration is particularly troublesome. A failing sensor may work when the engine is cold but lose its signal as temperatures rise, potentially causing the engine to cut out during operation.
• An inaccurate or unstable signal can also contribute to misfires, poor performance and engine-management warning lights.
• Because crankshaft position information is directly related to ignition and injection control, unresolved sensor faults can compromise overall engine reliability and may leave the vehicle unable to start.
• Replacing a defective component with this OE Match Crankshaft Position Sensor helps restore accurate engine speed and position information, dependable starting and correct engine-management operation.

Knock Sensor.

Restore accurate combustion monitoring and dependable engine-management operation with this OE Match Knock Sensor. Designed for compatible Porsche applications, the knock sensor monitors engine vibrations associated with abnormal combustion, allowing the engine control unit (ECU) to respond when detonation or engine knock is detected.

Fits:

Diagram Ref No 21

During normal operation, the ECU continually adjusts engine parameters to achieve an effective balance between performance, efficiency and engine protection. The knock sensor plays an important role in this process by detecting characteristic vibration frequencies produced when combustion does not occur as intended.

When knock is detected, the ECU can adjust ignition timing and other applicable operating parameters to reduce detonation. This helps protect internal engine components from the excessive pressure and temperature associated with prolonged engine knock.

A faulty knock sensor may provide an incorrect, intermittent or missing signal. This can trigger an engine-management warning and may cause the ECU to adopt more conservative ignition settings, potentially resulting in reduced performance or efficiency.

This OE Match Knock Sensor provides a high-quality replacement for a defective or damaged original sensor, helping restore accurate knock detection and correct engine-management response.

What This Product Does:

• Detects engine vibrations associated with detonation or abnormal combustion.
• Sends combustion vibration information to the ECU.
• Helps the engine-management system identify engine knock.
• Allows ignition timing to be adjusted when knock is detected.
• Helps protect internal engine components from damaging detonation.
• Supports optimum ignition timing under changing operating conditions.
• Helps maintain smooth and efficient combustion.
• Supports consistent engine performance and throttle response.
• Allows the ECU to adapt appropriately to engine load and operating conditions.
• Replaces a failed, damaged or unreliable knock sensor.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Knock sensor-related diagnostic trouble codes.
• Reduced engine power. Sluggish acceleration.
• Poor or inconsistent throttle response.
• Engine entering a reduced-performance or protective operating strategy.
• Increased fuel consumption.
• Rough or inconsistent engine operation.
• Audible pinging or knocking during acceleration.
• Knock particularly noticeable under heavy engine load.
• Intermittent engine-management warnings.
• Damaged knock sensor wiring or connector.
• Diagnostic testing showing an implausible, intermittent or missing sensor signal.  

Why Replacement Matters:

• Engine knock or detonation occurs when combustion inside the cylinder becomes abnormal, creating uncontrolled pressure waves rather than the intended smooth combustion process.
• Persistent detonation can expose pistons, bearings, cylinder walls and other internal engine components to increased mechanical and thermal stress. Severe or prolonged knock can potentially contribute to expensive internal engine damage.
• The knock sensor helps prevent this by giving the ECU the information needed to identify abnormal combustion and make appropriate ignition adjustments.
• If the sensor fails or sends unreliable information, the ECU may no longer be able to determine accurately whether knock is occurring. Depending on the engine-management strategy, it may compensate by using conservative ignition timing to provide additional engine protection.
• While this can reduce the risk of damage, it may also result in reduced power, poorer throttle response and increased fuel consumption.
• A defective sensor can also create persistent diagnostic faults or warning lights, making it more difficult to identify other genuine engine-management problems.
• Replacing a failed sensor with this OE Match Knock Sensor helps restore accurate combustion monitoring, appropriate ignition control and the engine protection functions built into the management system.

Diagram Ref No 7

The sensor is installed in conjunction with the rear brake pad assembly and connected to the vehicle's electrical monitoring circuit. As the brake pad friction material wears down, the sensor eventually reaches the brake disc. Once the sensor is worn through, the circuit changes and the vehicle can display a brake pad wear warning.

Brake wear sensors are often replaced at the same time as the brake pads. If a sensor has already contacted the brake disc, its sensing element may be permanently worn and unsuitable for reuse. Wiring, insulation and connectors can also deteriorate or become damaged during servicing.

This OE Match Rear Brake Pad Wear Sensor provides a replacement solution for a worn, damaged or defective sensor, helping restore correct operation of the brake pad wear warning system.

What This Product Does:

• Monitors the wear condition of the rear brake pads.
• Works with the vehicle's brake wear monitoring system.
• Helps trigger a dashboard warning when the pads reach their specified wear threshold.
• Alerts the driver that brake inspection and servicing are required.
• Helps prevent brake pad wear from going unnoticed.
• Provides an electrical connection between the brake assembly and monitoring system.
• Replaces a sensor that has been worn through during normal brake pad wear.
• Replaces damaged or defective sensor wiring. Helps restore correct brake wear warning functionality following brake servicing.
• Provides an OE Match alternative for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Brake pad wear warning displayed on the dashboard.
• Brake service warning remaining active after new pads have been installed.
• Sensor tip visibly worn through.
• Broken or damaged sensor wiring.
• Cracked or deteriorated cable insulation.
• Damaged electrical connectors.
• Intermittent brake pad wear warnings.
• Warning appearing when the brake pads still have adequate friction material.
• Wiring detached from its retaining clips.
• Sensor damaged during brake pad or disc replacement.
• Corrosion or contamination around the electrical connection.
• Diagnostic testing indicating a fault in the brake wear monitoring circuit.  

Why Replacement Matters:

• The brake pad wear sensor provides the driver with an important indication that brake servicing is required. If the sensor is damaged or the monitoring circuit is no longer functioning correctly, the vehicle may be unable to provide an accurate warning as the pads wear.
• Continuing to use brake pads beyond their service limit can eventually allow the pad backing material to contact the brake disc. This can damage the disc and potentially reduce braking performance, turning a routine pad replacement into a more extensive brake repair.
• Once a wear sensor has contacted the brake disc and triggered the warning, the sensing element may be physically worn through. Reusing that sensor with new pads can leave the warning system unable to function correctly.
• A damaged sensor can also create the opposite problem, causing a persistent warning even though the brake pads remain serviceable.
• Replacing a worn or defective component with this OE Match Rear Brake Pad Wear Sensor helps restore reliable brake pad monitoring and ensures the vehicle can provide the intended warning when future rear brake service is required.

Fog light switch, Yellow tip
The 901 613 503 20 is a dashboard-mounted mechanical or push-pull switch used in early Porsche 911 / 911S / 911L and 912 models (1960s era) to activate the front fog lights. It is often grouped with the rear-window heating and warning-light switches, depending on vehicle specification.

In use, pulling or pressing the switch completes the circuit for the fog lights, sending power (via fuse and relay) to the fog lamp units. The switch usually has an internal light (“light-pipe”) or indicator so you can tell when fog lights are active. 

Fits:

• Porsche 911 65-68 + 911S, 912 USA version 911L with yellow lighting strip
• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 912E 4CYL 1976  

Why / when it should be replaced

·         Even though the fog light switch is a relatively simple component, there are several reasons why it might need replacing:

·         Internal wear or contact failure. Over time, the internal contacts inside the switch can wear, corrode, or lose tension, leading to poor electrical contact. If that happens, the fog lights may not activate when the switch is engaged.

·         No illumination of the switch itself. On models where the switch includes a light-pipe or internal lamp so that you can see the switch position, failure of that internal illumination can make it harder to know whether the fog lights are on and may indicate internal switch failure.

·         Switch stuck or mechanically broken. The pull/knob mechanism may become sticky, stuck, or physically break, especially after decades of use, or due to heat/cockpit environment ageing. A switch that doesn’t move properly or won’t stay in the “on” position cannot reliably activate the fog lights.

·         Intermittent operation / flickering. Even if the switch appears to work, intermittent contact inside the switch might cause the fog lights to flicker, drop out, or not turn off properly.

·         Fuse or wiring feedback problems. In some cases, a failing switch can lead to blown fog-light fuses or feedback to wiring loops, especially if there is an internal short or poor contact. Replacing the switch may be required after troubleshooting electrical issues.

The radiator fan is a critical part of a water-cooled engine's thermal management system. While airflow through the radiator naturally increases when the vehicle is moving, additional forced airflow is required when driving slowly, sitting in traffic or operating under conditions where natural airflow is insufficient. The electric fan draws or pushes air through the radiator as required, allowing heat to be transferred from the engine coolant to the surrounding air.

A worn or failed radiator fan can significantly reduce cooling efficiency, particularly at low road speeds. Problems can develop through motor wear, damaged fan blades, worn bearings, electrical faults or physical damage to the assembly.

This OE Match 400W, 370mm Radiator Water Fan provides a high-quality replacement for a defective original unit, helping restore controlled coolant temperatures and reliable cooling-system performance.

• Radiator fan failing to operate when required.
• Fan operating intermittently.
• Fan rotating more slowly than expected.
• Unusual grinding, scraping or rattling noises.
• Excessive vibration from the fan assembly.
• Squealing or bearing noise from the fan motor.
• Damaged, cracked or broken fan blades.
• Fan blades contacting the surrounding housing or shroud.
• Fan motor overheating or failing electrically.
• Cooling-system or fan-related warning messages.
• Diagnostic fault codes relating to cooling fan operation.  

Why Replacement Matters:

• Maintaining the correct engine operating temperature is essential for performance, reliability and engine longevity. The radiator can only dissipate heat effectively when sufficient air passes through its cooling fins.
• At motorway speeds, vehicle movement generally provides substantial airflow. At idle or in slow traffic, however, the electric radiator fan becomes much more important. If the fan is unable to operate correctly, coolant temperature can rise rapidly despite the rest of the cooling system being functional.
• Repeated or severe overheating can have serious consequences. Excessive temperature can damage seals and gaskets, accelerate deterioration of cooling-system components and, in extreme circumstances, contribute to cylinder-head or engine damage.
• A damaged fan blade or worn motor bearing should also be addressed promptly. Excessive vibration can place additional stress on the fan assembly and surrounding components, while a damaged blade may eventually contact the shroud or fail completely.
• Replacing a defective unit with this OE Match Radiator Water Fan helps restore reliable radiator airflow, stable coolant temperatures and dependable engine cooling.

Engine Cover.

Restore the correct engine compartment protection, airflow management and original-style appearance with this OE Match Engine Cover. Designed for compatible Porsche applications, this component forms part of the engine's surrounding cover and cooling-air management system.

Fits:

• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50  

Diagram Ref No 3

On an air-cooled Porsche engine, engine covers and surrounding tinware perform an important function beyond simply providing a finished appearance. These components help guide cooling air through the intended areas of the engine and separate hot and cool zones within the engine compartment.
The engine cover is exposed to continuous heat cycles, vibration, moisture and contamination. Over time, an original component can become corroded, distorted, cracked or damaged around its mounting points. Covers may also be lost or incorrectly fitted during previous engine repairs or restoration work.
This OE Match Engine Cover provides a high-quality replacement for a damaged, corroded, missing or unsuitable original component, helping restore the integrity of the engine's cover arrangement.
What This Product Does:

• Forms part of the engine's surrounding cover and tinware system.
• Helps manage airflow around the engine.
• Supports the correct routing of cooling air on applicable air-cooled engines.
• Helps separate different temperature zones within the engine compartment.
• Closes gaps that could allow cooling air to escape from its intended path.
• Provides protection for associated engine areas.
• Helps reduce exposure to dirt and debris.
• Supports correct installation of surrounding engine tinware and seals.
• Helps maintain a clean and complete engine compartment appearance.
• Replaces a corroded, bent, damaged or missing engine cover.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Visible rust or corrosion.
• Corrosion perforating the cover.
• Cracks or splits in the component.
• Bent or distorted sections.
• Damaged mounting holes or fixing points.
• Loose or missing fasteners.
• Rattling or vibration from the engine cover.
• The cover no longer fitting correctly against adjacent components.
• Unwanted gaps in the engine tinware.
• Evidence that the original cover is missing.
• An incorrect component fitted during previous repairs.
• Damage discovered during engine removal or rebuilding.
• Deterioration affecting the appearance of the engine compartment.  

Why Replacement Matters:

• Air-cooled engines rely heavily on correctly managed airflow to control operating temperature. The various engine covers, air guides, seals and pieces of tinware work together to ensure cooling air travels through the intended areas.
• If an engine cover is missing, badly distorted or incorrectly installed, unwanted gaps may allow cooling air to escape or hot air to circulate where it should not. Maintaining the complete engine tinware arrangement therefore helps the cooling system perform as designed.
• A damaged cover can also create mechanical issues. Loose or distorted sections may vibrate against surrounding components, producing rattling noises and potentially causing further wear.
• Corrosion is particularly relevant on older vehicles. Moisture can gradually weaken the cover, especially around mounting points and edges. Once these areas deteriorate significantly, the component may no longer remain securely positioned.
• For a restored classic Porsche, correctly fitted engine covers are also important to the overall presentation of the engine compartment. Missing, heavily corroded or incorrectly shaped components can detract from an otherwise high-quality restoration.
• Replacing a deteriorated component with this OE Match Engine Cover helps restore the completeness of the engine cover system, support proper cooling-air management and maintain an original-style engine compartment finish.

Front Engine Cover Blade With Hole.

Restore the correct fit, protection and original-style finish of the engine assembly with this OE Match Front Engine Cover Blade with Hole. Designed for compatible Porsche engine applications, this component forms part of the engine's surrounding cover and air-management arrangement.
Fits:

• Porsche 911 1978-1979 SC (PR399 A/C Without Front Condensor)

Diagram Ref No 10

On an air-cooled Porsche engine, the various covers, plates and sealing pieces around the engine are more than cosmetic components. They help control the path of cooling air and separate different areas around the engine so that airflow can be directed where intended.

This particular front engine cover blade features the required hole for its intended application. Correct component specification is therefore important when replacing a missing, damaged, corroded or incorrectly fitted original part.

Exposure to engine heat, vibration, moisture and previous servicing can cause engine cover components to corrode, distort or become damaged. Missing or incorrectly fitted pieces may also compromise the completeness of the engine's cooling-air arrangement.
What This Product Does:

• Forms part of the engine's surrounding cover arrangement.
• Helps maintain the intended separation of areas around the engine.
• Supports correct management of cooling airflow on applicable air-cooled engines.
• Helps close unwanted gaps around the engine cover system.
• Features the appropriate hole for the intended installation.
• Helps protect surrounding areas from debris and contamination.
• Supports a complete and correctly assembled engine installation.
• Replaces a missing, corroded, bent or damaged original component.
• Helps restore an original-style appearance to the engine compartment.
• Provides an OE-style replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Visible corrosion or rust.
• Perforation caused by corrosion.
• Bending or distortion.
• Cracks or physical damage.
• Damaged mounting points.
• Loose or missing mounting hardware.
• The cover blade vibrating or rattling while the engine is running.
• Gaps caused by an incorrectly fitting component.
• The original cover blade is missing.
• An incorrect non-holed or otherwise unsuitable component has previously been installed.
• Damage discovered during engine removal or rebuilding.
• Deterioration affecting the appearance of the engine compartment.  

Why Replacement Matters:

• Air-cooled Porsche engines depend on controlled airflow for effective temperature management. Engine cover and sealing components help ensure cooling air follows its intended path rather than escaping through unnecessary openings.
• A missing, badly damaged or incorrectly fitted cover component may create gaps in the engine's surrounding air-management system. While a single panel is only one part of the complete arrangement, maintaining all covers and seals in their correct positions helps the overall cooling system operate as intended.
• Physical damage can also create fitment problems. A bent or distorted blade may interfere with neighbouring components, produce rattles or prevent associated engine covers from fitting correctly.
• Corrosion is another common concern on older vehicles. Once rust has significantly weakened the component or affected its mounting points, replacement may provide a more reliable solution than attempting to retain a heavily deteriorated original.
• For restoration projects, correct engine tinware and cover components also contribute significantly to an authentic and properly finished engine compartment.
• Replacing a deteriorated or missing component with this OE Match Front Engine Cover Blade with Hole helps restore the completeness of the engine cover system, support proper cooling-air management and maintain an OE-style appearance.

Why Do Valve Covers and Gaskets Fail?

Valve covers are exposed to constant engine heat, vibration and repeated heating and cooling cycles. Over time, covers can become damaged or distorted, while the sealing gaskets gradually harden and lose their ability to maintain an effective seal.

Common problems include:

• Oil leaks around the valve cover
• Hardened or deteriorated gaskets
• Distorted sealing surfaces
• Cracked or damaged covers
• Damaged mounting points
• Previous over-tightening of mounting hardware

Oil visible around the valve cover or cylinder head area can indicate that inspection is required.
