Description

Thermostat – the coolant-flow control valve in the engine cooling system, with an 82C opening temperature.

Mounted in the thermostat housing at the coolant outlet on the cylinder head, it stays closed while the engine warms from cold so coolant circulates only within the block, then opens progressively from 82C to route coolant through the radiator and hold the engine at its intended operating temperature. Suits both petrol and diesel applications.
