11 53 1 436 386 : Water thermostat 105°C for BMW Series 5 E39 8-cylinder

This water thermostat with an opening threshold of 105°C is a replacement part intended for the BMW Series 5 E39 equipped with the 8-cylinder M62 engine, in the Saloon 535i M62, Saloon 540i M62 and Touring 540i M62 versions, from September 1998 onwards. The thermostat regulates the coolant temperature by controlling its circulation between the engine and the radiator: a faulty part can lead to engine overheating or running too cold. As part of the restoration or maintenance of a classic E39, its replacement with a new part conforming to original specifications guarantees reliable thermal operation. It is an essential preventive intervention to preserve the longevity of a carefully maintained M62 engine.
