Eurospare PEL500110R Engine Coolant Thermostat Grey 82C Soft Spring

The Eurospare PEL500110R is a grey, soft-spring engine coolant thermostat designed as a direct OE-quality replacement for Land Rover K4 petrol engines. Identified by its distinctive grey color, this thermostat features a light (soft) spring design and an 82°C (180°F) opening temperature, making it the correct specification for warm-weather climate applications.

The thermostat plays a critical role in the engine's cooling system by regulating coolant flow between the engine and radiator. When the engine is cold, the thermostat remains closed to allow rapid warm-up. Once the coolant reaches the rated 82°C threshold, the thermostat begins to open, allowing coolant to circulate through the radiator and maintain stable operating temperatures. A failed thermostat can lead to overheating or poor engine efficiency, making timely replacement essential.
