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.

- Porsche 997.2 Turbo 2010 - 2013
Diagram ref no 8
What This Product Does
The thermostat is a control component within the transmission cooling arrangement, helping regulate its operation rather than serving as the oil cooler itself. OE Match develops replacement parts around Porsche applications, using original references and component specifications when assessing fit and function.
Symptoms of Fault
Transmission temperature warnings, rough changes when hot, delayed engagement or fluid leakage can justify inspecting the cooling system. These signs do not establish thermostat failure: cooler restrictions, damaged lines, seals and other transmission faults may produce similar symptoms.
Why Replacement Matters
Renewal is appropriate when diagnosis identifies a defective control component. Inspect associated hoses, connections and seals during the repair, and match the replacement to the vehicle's transmission specification.
FAQs
Will flushing resolve a faulty thermostat?
Flushing may address contamination, but it does not repair a defective component or leaking connection.
Does difficult shifting confirm a cooling fault?
No. Fluid condition, transmission controls and other drivetrain components should also be assessed before replacement.
