Thermostat Housing – the coolant thermostat housing for the 1.8L 4-cylinder K Series petrol engine, part of the engine cooling circuit.

The housing seals the coolant passage and provides the mounting point for the thermostat within the circuit.

Supplied as the housing only – the thermostat is not included. This applies to the configuration using the external thermostat; the companion thermostat is PEL500110.
