Job it does: forms the sealing joint between the coolant thermostat and its housing so coolant stays in the passage.
Signs it may need replacing: coolant seepage, drips, or crusty residue around the thermostat housing.
When to fit it: a smart replacement whenever the thermostat or its housing is opened up, so the joint reseals cleanly.
If a worn or leaking seal at the thermostat is the cause of your coolant loss, this replaces it. Diagnose the source of the leak before ordering.
It forms the sealing joint between the engine coolant thermostat and its housing, keeping coolant in the passage and out of the surrounding area.
