Product Information
Product Information

Water pump & thermostat insert kit for Porsche Cayenne 9PA1 (957) 4.5L models, combining key cooling components in one package to support correct fit and temperature control.

What This Product Does This kit groups a replacement water pump with a thermostat insert and sealing components so the main cooling and temperature-control parts can be renewed together. Servicing these items at the same time helps maintain stable engine temperature and consistent coolant circulation.

Functions

  • Circulates coolant through the engine and radiator via the water pump
  • Controls coolant flow with the thermostat to regulate operating temperature
  • Allows combined renewal of related cooling components in one job
  • Helps reduce the risk of leaks from aged housings and seals
  • Supports reliable warm-up and stable running temperature

Symptoms of Fault

  • Coolant leaks or dried residue around the water pump or thermostat area
  • Rising or fluctuating temperature gauge, especially under load
  • Coolant smell after driving or visible puddles under the front of the vehicle
  • Whining or grinding noises from the pump/belt area
  • Repeated low coolant warnings or intermittent overheating
  • Poor cabin heat or slow warm-up linked to thermostat issues

Why Replacement Matters

Age, mileage and heat cycles can cause water pump bearings, seals, housings and thermostat mechanisms to wear. This may show as leaks, noise, unstable temperature or warning messages. Replacing the pump and thermostat insert together reduces duplicate labour, helps restore dependable coolant circulation and temperature control, and lowers the risk of overheating-related engine damage, particularly on higher-mileage Cayenne V8 models.

Product Information
Product Information
80°C Thermostat.
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.
