Your engine's thermostat regulates coolant flow and temperature in the cooling system. When open it allows coolant to flow into the radiator to be cooled. When closed the coolant circulates through the engine, where it stays warm. A failed thermostat will either be open or closed with the engine running too cold (poor fuel economy and performance) or too hot (overheating). It can also impact your cabin heating/cooling since that is drawn from your heater core.

BMW used the same design of thermostat for many models from the 1980s-1990s but with different temperature ratings. This is the 75C degree thermostat (towards the coolest end of the temp scale). Thermostats are interchangeable among the models listed below but note that using a non-standard thermostat will alter your engine's performance. On other models this may be a Performance thermostat used with engine fan delete kits.

This is a thermostat made by Vernet, an OEM thermostat supplier to several European manufacturers since the 1950s. The o-ring seal is included but a housing profile gasket is sold separately.
