Fitted on the gearbox side cylinder head, it has the task of keeping the engine at the optimum temperature:
at a temperature of < 87 ± 2°C the (closed) thermostatic valve directs the coolant directly towards the pump
at a temperature of > 87 ± 2°C the (open) thermostatic valve directs the coolant towards the radiator.
Mounted on the thermostat, there is the coolant temperature sensor connected to the fuel injection control unit.
