This OE Match water pump thermostat is a replacement cooling system thermostat for Porsche 924S and 944 models. It is designed to match the original-style fitment and function, helping regulate coolant flow and maintain the correct engine operating temperature.
Fits:
Porsche 924S 1986 - 1988
Porsche 944 1982 - 1988
Diagram Ref No 3.
The thermostat controls coolant flow through the engine cooling system. When the engine is cold, it helps restrict coolant circulation so the engine can warm up efficiently. Once the correct temperature is reached, it opens to allow coolant to circulate through the radiator and cooling system.
Functions
• Replaces the water pump thermostat
• Helps regulate engine coolant flow
• Supports correct engine warm-up and operating temperature
• Helps maintain cooling system efficiency
• Helps prevent overheating or overcooling issues
• Replaces stuck, leaking, slow-opening, or failed original thermostats
• OE Match replacement for Porsche 924S and 944 cooling system service.
Why Replace This Part?
Thermostats can fail due to age, coolant contamination, corrosion, sticking, worn seals, or repeated heat cycles. A faulty thermostat may stay closed and cause overheating, or stay open and prevent the engine from reaching the correct operating temperature. Replacing the thermostat helps restore reliable temperature control and protects the engine cooling system.
When to Replace This Part
• The engine overheats or runs hotter than normal
• The engine takes too long to warm up
• Coolant temperature fluctuates or remains too low
• The thermostat is stuck open or closed
• The water pump or cooling system is being serviced
• Coolant has become contaminated or the system is being flushed
• Preventative replacement is being carried out during major service.
Where it fits on the car
This thermostat fits within the water pump / engine cooling system on Porsche 924S and 944 models. It controls coolant flow according to the factory cooling system layout. Applications / F

• 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.
