Diagram Ref No 5
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.

Porsche 997 2005 - 2008
Installation recommended only by trained Porsche technician or Porsche service department using genuine Porsche coolant.
Diagram Ref No 5, 6
This OE Match water thermostat with insert is a replacement engine cooling system component. The low temperature 160F / 71°C specification allows the thermostat to begin opening at a lower temperature, helping coolant circulate through the radiator earlier during engine warm-up and operation.
The thermostat controls coolant flow between the engine and radiator. When the engine reaches the thermostat opening temperature, it allows coolant to circulate through the cooling system to help regulate engine operating temperature and maintain stable cooling performance.
Functions
• Replaces the water thermostat and insert
• Low temperature 160F / 71°C opening specification
• Helps regulate engine coolant flow
• Allows earlier coolant circulation through the radiator
• Supports stable engine temperature control
• Suitable for cooling system service or performance-focused maintenance
• OE Match replacement for Porsche Boxster, 996, and 997 cooling systems.
Why Replace This Part?
Thermostats can fail due to age, heat cycles, coolant contamination, corrosion, internal sticking, or seal wear. A faulty thermostat may stick open or closed, causing slow warm-up, overheating, unstable temperature readings, poor heater performance, or coolant flow issues. Replacing the thermostat helps restore correct cooling system operation and temperature regulation.
When to Replace This Part
• Engine temperature is unstable
• The engine is overheating
• The thermostat is stuck open or closed
• Cooling system service is being carried out
• Coolant is being flushed or renewed
• Preventative cooling system maintenance is required
• A low temperature thermostat is desired for earlier coolant circulation.
Where it fits on the car
This thermostat fits within the engine cooling system / thermostat housing area on Porsche 986 Boxster, 996, 987 Boxster, and 997 models. It controls coolant flow between the engine and radiator circuit.

About Thermostat / Temperature Sensor
OEMatch Thermostat / Temperature Sensor — Fit, Function, Confidence
Engine thermostats and temperature sensors control coolant flow and send temperature data to the engine control unit, helping to maintain correct operating temperature for Porsche models. Proper function supports warm-up, emissions control and cabin heating, and reduces the risk of avoidable engine stress. OEMatch focuses on Thermostat / Temperature Sensor-related items selected for Porsche applications.
Available Types
- Fixed-opening and temperature-controlled thermostats
- Coolant temperature sensors and senders (engine and radiator)
- Thermostat housings and integrated sender assemblies
Understanding OEMatch Thermostat / Temperature Sensor
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original thermostat / temperature sensor. OE (Original Equipment) refers to parts matching original specifications for the thermostat / temperature sensor and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM thermostat / temperature sensor engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. A thermostat opens at a specified temperature to allow coolant to circulate through the radiator, while temperature sensors measure coolant or cylinder head temperature and inform fan control, fuel mixture and emissions strategies. Both components work together to keep the engine within its designed operating window and to support reliable vehicle operation.
Benefits Include
- Stable engine operating temperature and predictable warm-up
- Accurate temperature input for ECU control and cooling fans
- Consistent cabin heating and support for emissions systems
Why Thermostat / Temperature Sensor Wear and Fail
- Thermostat valve sticking or corrosion caused by debris and old coolant
- Sensor degradation from prolonged heat exposure and contaminated coolant
- Electrical faults, corroded connectors or damaged wiring affecting readings
The Importance of Replacing with OEMatch Thermostat / Temperature Sensor
Replacing worn or faulty thermostats and sensors restores reliable temperature control and helps prevent overheating, long warm-up times and poor fuel economy. Correctly matched replacements reduce the chance of installation issues and support consistent ECU behaviour, heater performance and long-term engine condition across Porsche model ranges.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Components selected for compatibility with factory cooling circuits and mounting points
- Cost-effective alternatives that preserve fit and function for Porsche applications
Support & Advice
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
