Engine coolant control valve
Genuine Porsche valve for controlling engine coolant flow on the 944 S, 944 S2 and 968.
Fits
Porsche 944 S / S2 1987 - 1991
Porsche 968 1992 - 1995
Diagram ref 25
What This Product Does
The valve regulates coolant passage within its fitted circuit. Correct operation depends on the valve and surrounding connections remaining free from leakage and restriction. It is a coolant-flow component, rather than a temperature sensor.
Functions
- Controls coolant passage through the connected circuit.
- Provides the valve function within the applicable cooling assembly.
Symptoms of Fault
Possible cooling-system warning signs include a falling coolant level, damp connections, dried coolant deposits, a sweet odour or an unusually high temperature reading. These symptoms do not identify the valve alone; inspect the surrounding hoses and connections before deciding which component requires renewal.
Why Replacement Matters
Renewing a confirmed leaking or malfunctioning valve helps restore coolant control in the affected circuit. Check associated hoses, clamps and seals during the repair so that deterioration elsewhere is not overlooked.
FAQs
How should suitability be confirmed?
Match the vehicle details and existing component identification before ordering. The supplied legacy reference, Porsche 924 Heater valve 477819017, has not been confirmed as applicable to this valve.
Do coolant leaks always indicate valve failure?
No. Nearby hoses, joints and other cooling components can produce similar symptoms, so establish the source first.

Engine coolant control valve
OE Match engine coolant control valve for Porsche 944 S, 944 S2 and 968 applications. This replacement component controls coolant passage within the circuit in which it is installed.
Fits
Porsche 944 S / S2 1987 - 1991
Porsche 968 1992 - 1995
Diagram reference: 25.
What This Product Does
The valve opens or restricts a coolant passage as part of the vehicle's coolant-control arrangement. It is a flow-control component, rather than an electrical temperature sensor; temperature readings alone do not establish whether it needs replacement.
Functions
- Controls coolant passage through its installed circuit.
- Provides a replacement for a leaking or malfunctioning coolant valve.
Technical Details
Supplied internal diagrams also identify reference 92857457305 as a disc valve in the following transmission-cooling assemblies. These diagram applications are additional reference context; confirm the required part reference before installation.
Symptoms of Fault
Coolant seepage, dried deposits near connections, a falling coolant level or an unusual coolant smell warrant inspection. Poor cabin heating or abnormal engine temperature can also accompany cooling-system problems, but these symptoms are not specific to this valve.
Why Replacement Matters
Renewing a confirmed faulty valve addresses leakage or incorrect coolant passage. Inspect adjoining hoses, clips and sealing points during the repair, because deterioration elsewhere can produce similar symptoms. OE Match develops replacement components around Porsche applications, with specification checks and sample evaluation forming part of its product programme.
FAQs
- Should overheating be treated as proof of valve failure?
No. Establish the cause before replacing components; coolant loss and other cooling-system faults can produce similar behaviour. - What should be checked before fitting?
Confirm the vehicle details and original reference, then examine nearby connections and supporting components. - How can a coolant leak be investigated?
Inspect for dampness or deposits and arrange a cooling-system pressure test where necessary.

• Position on Vehicle: Mounted in the engine cooling system, often on the engine block or near the thermostat housing, where it measures coolant temperature for sensor input.
• Cross-Reference / Alternative Numbers: OEM part number: 928 606 201 01 (also shown as 92860620101)
• Applications: Replacement when the original sensor fails, provides inaccurate readings, or exhibits corrosion or damage - ensuring the cooling system and engine management continue to operate correctly.
The coolant temperature sensor is a vital component for engine management: it relays vital temperature information to the ECU, radiator fans, and drivers’ gauges. If the sensor becomes faulty, you may experience incorrect temperature readings, poor cooling-fan operation, unpredictable engine behaviour or even overheating. Replacing it with a quality OE-Match unit ensures accurate temperature detection, proper fan control, consistent engine performance and safeguarding of your cooling system.
When and why to replace:
• Incorrect or fluctuating temperature gauge readings.
• Radiator fan runs constantly or not at all, indicating bad sensor input.
• Engine overheats or cooling system fails to engage properly.
• Visible corrosion, damage or leakage at the sensor housing.
• As part of a cooling-system overhaul or when replacing thermostat, water pump or related components.

Engine Thermostats & Temperature Sensors – Precision Cooling Control for Porsche Performance
Engine thermostats and temperature sensors are essential components in your Porsche’s cooling system. Together, they regulate and monitor engine temperature to ensure optimal performance, efficiency, and reliability. The thermostat controls coolant flow through the radiator, while the temperature sensor communicates vital data to the vehicle’s ECU - helping to maintain the perfect balance between power and protection.
At Design911, we supply a wide range of genuine and high-quality thermostats and temperature sensors for Porsche models including transaxle cars, 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is engineered to precise standards for seamless integration, fast response, and long-lasting accuracy - ensuring your Porsche performs at its peak in all conditions.
What Do Engine Thermostats & Temperature Sensors Do?
These components work hand-in-hand to manage and monitor
your Porsche’s engine temperature:
- Thermostat:
Opens and closes to regulate coolant flow between the engine and radiator.
- Temperature
Sensor: Measures coolant or cylinder head temperature and sends data
to the ECU to control fans, fuel mixture, and performance parameters.
- Together: They maintain optimal operating temperatures, prevent overheating, and ensure efficient combustion and emissions control.
Without a properly functioning thermostat or temperature sensor, your engine can overheat, run inefficiently, or suffer from poor fuel economy.
Why Do Thermostats & Temperature Sensors Fail?
These components operate under constant thermal stress and
can degrade over time. Common causes of failure include:
- Thermostat
sticking open or closed due to corrosion or wear.
- Sensor
degradation from prolonged exposure to coolant and heat.
- Electrical
faults or corrosion in wiring and connectors.
- Contamination
from old or incorrect coolant types.
- Age-related fatigue causing inaccurate readings or slow response.
Symptoms of failure include fluctuating engine temperatures, warning lights, poor heating performance, or inconsistent fuel economy.
Why Replace Faulty Thermostats & Temperature Sensors?
A malfunctioning thermostat or temperature sensor can severely impact cooling efficiency and engine safety. Replacing worn or faulty parts restores accurate temperature control and helps prevent costly engine damage.
Benefits of replacement include:
- Stable engine operating temperature.
- Improved performance and fuel efficiency.
- Prevention of overheating or over-cooling.
- Manufacturer-quality construction for accuracy and durability.
All thermostats and sensors in this range are built to meet or exceed exacting standards, offering precise calibration, corrosion-resistant materials, and reliable long-term operation.
