- Porsche 957 Cayenne 3.6L 2007-10
The OE MATCH 80°C Thermostat is a replacement engine cooling-system thermostat designed to regulate coolant circulation and help maintain controlled engine operating temperatures.
Fits:
- Porsche 957 Cayenne 3.6L 2007-10
Diagram Ref No 11
With an 80°C temperature rating, this thermostat begins regulating coolant flow according to its specified operating range. It provides an alternative replacement option for compatible applications where an 80°C thermostat is required.
What This Product Does:
The thermostat acts as a temperature-controlled valve within the engine cooling circuit.
When the engine is cold, the thermostat restricts coolant circulation through the radiator. This helps the engine reach its normal operating temperature efficiently.
As coolant temperature increases towards the thermostat's operating range, the thermostat opens to allow increased coolant circulation through the radiator. Heat can then be transferred away from the engine.
The 80°C thermostat helps:
- Regulate engine coolant circulation
- Control engine operating temperature
- Allow efficient engine warm-up
- Increase radiator coolant flow as temperature rises
- Reduce the risk of excessive engine temperatures
- Maintain more consistent cooling-system operation
- Support dependable engine performance
Symptoms Of Wear Or Failure:
Thermostats are continually exposed to hot coolant and repeated heating and cooling cycles. Over time, the internal mechanism can deteriorate, become sluggish or seize.
Common symptoms of thermostat problems include:
- Engine overheating
- Engine running hotter than expected
- Temperature gauge fluctuating unexpectedly
- Sudden increases in coolant temperature
- Engine taking too long to warm up
- Engine consistently running too cool
- Poor or inconsistent cabin heater performance
- Cooling fans operating unusually frequently
- Coolant temperature warning messages
- Changes in fuel economyInconsistent engine operating temperature
The symptoms will depend largely on whether the thermostat has become stuck closed, stuck open or is only partially opening.
Why Replacement Matters:
Maintaining controlled engine temperature is essential for reliable performance and engine protection.
A correctly functioning thermostat balances two competing requirements: allowing the engine to warm up efficiently while providing sufficient coolant circulation when temperatures increase.
Replacing a worn or malfunctioning thermostat can help restore:
- Controlled coolant circulation
- Stable engine temperature
- Effective radiator cooling
- Predictable engine warm-up
- Consistent heater performance
- Efficient engine operation
- Protection against overheating
Ignoring thermostat problems can place unnecessary stress on the cooling system and, in cases of severe overheating, potentially result in expensive engine damage.

Manufactured to OE specifications for fit, durability and cooling performance, the assembly features a precision-engineered thermostat housed within a robust, heat-resistant housing. The thermostat remains closed during engine warm-up to allow the engine to reach its correct operating temperature quickly before opening at approximately 83°C to allow coolant to circulate through the radiator, preventing overheating while maintaining efficient engine operation.
What This Product Does:
- Regulates coolant flow throughout the engine cooling system.
- Opens at approximately 83°C to maintain the correct engine operating temperature.
- Speeds up engine warm-up after a cold start.
- Prevents engine overheating during normal operation.
- Improves fuel efficiency by maintaining optimum engine temperature.
- Supports efficient cabin heater performance.
- Includes a new housing, thermostat insert and gasket for a complete installation.
Symptoms Of Wear Or Failure:
- Engine overheating.
- Engine taking an unusually long time to reach operating temperature.
- Fluctuating temperature gauge readings.
- Coolant leaks around the thermostat housing.
- Low coolant level warnings.
- Poor cabin heater performance.
- Engine running too hot or too cold.
- Illuminated engine or cooling system warning lights.
- Visible cracks or damage to the thermostat housing.
- Increased fuel consumption caused by incorrect engine temperature.
Why Replacement Matters:
- The thermostat and housing are essential components of the engine cooling system and are continuously exposed to heat cycles, coolant pressure and engine vibration. Over time, the thermostat can stick open or closed, while the housing and seals may deteriorate or develop leaks.
- A thermostat that remains closed can quickly cause engine overheating, while one that remains open prevents the engine from reaching its correct operating temperature. Both conditions reduce engine efficiency, increase fuel consumption and can lead to premature engine wear. Coolant leaks from a damaged housing can also result in coolant loss and severe engine damage if left unresolved.
- Replacing the complete thermostat housing assembly with a new thermostat insert and gasket restores correct coolant regulation, improves engine efficiency and protects against overheating. An OE Match replacement provides factory-style fitment, reliable temperature control and long-lasting durability, helping maintain the performance, reliability and longevity expected from your Porsche.

This essential engine management component monitors coolant temperature and sends information to the engine control unit (ECU), helping regulate fuel delivery, engine performance and cooling system operation.
Designed as an original-style replacement, it helps restore accurate temperature monitoring and reliable engine operation when the original sensor becomes faulty.
What Does the Water Temperature Sensor Do?
The sensor measures engine coolant temperature and sends an electrical signal to the ECU.
This information helps the engine management system adjust fuel mixture, cold-start operation and other temperature-dependent functions, ensuring efficient engine performance.
Why Does It Fail?
Over time, repeated heating and cooling cycles, moisture and electrical deterioration can affect sensor accuracy.
Common problems include:
- Internal sensor failure
- Corroded or damaged electrical connections
- Incorrect or fluctuating temperature readings
- Intermittent electrical signals
- Damage caused by coolant leaks or overheating
When Should It Be Replaced?
Replacement may be necessary if you experience:
- Incorrect or erratic engine temperature readings
- Difficult cold starting or poor warm-up performance
- Increased fuel consumption
- Engine management warning lights
- Cooling fan operation that appears abnormal
Before replacement, check the coolant level, electrical connector, wiring and relevant fault codes to confirm the cause.
Additional 996 variants may have different sensor arrangements. Confirm compatibility using the original part number or vehicle VIN before ordering.
Porsche Boxster 986 & 911 996 Coolant Temperature Sensors
The coolant temperature sensor plays an important role in the engine management system of water-cooled Porsche models, providing accurate temperature information for efficient engine operation.
A faulty sensor can cause incorrect temperature readings, poor cold starting, increased fuel consumption and engine management faults.
