Original BMW Thermostat Housing for BMW E39 M5 and E52 Z8 (2000–2003)

Coolant leaving the S62 V8 in the 2000–2003 BMW M5 and Z8 passes through this Original BMW thermostat housing, part 11-53-1-406-762, which holds the coolant thermostat and connects the engine to the radiator hoses. The thermostat inside it opens and closes with coolant temperature, regulating the flow of coolant to and from the engine and controlling operating temperature. A thermostat stays shut on a cold engine so it warms up quickly, then opens to send coolant out to the radiator. This housing is made in Germany and comes with its seal. BMW names it simply thermostat housing, sells it as one piece, and shows production starting in September 1998.

Original BMW Parts carry a 24-month parts warranty.

BMW's parts data shows this housing only on the S62 engine, in the E39 M5 and the E52 Z8. A housing can fail in more than one way. It can crack or corrode on its own, or the gasket that seals it to the engine can give out. Either problem shows up as a coolant leak, and because the seal comes in the box, both are addressed with this one part.

Common Questions

What are the signs of a failing thermostat housing?
A coolant leak at the housing is the most common sign, caused by a crack, corrosion, or a failed gasket. A damaged housing, or a thermostat stuck closed, can also stop coolant from circulating and lead to overheating.

Can a bad housing affect the temperature gauge?
Yes. A malfunctioning thermostat or housing can let engine temperature fluctuate, and the dashboard gauge may move unpredictably as a result.

Keep your S62 cooling system on factory parts with this housing from PMB.
