Thermostat, Genuine BMW - E60, F10, E63, F13, E65, F02, X5/X6, M2/M3/M4

This is a direct replacement thermostat for the N62/N63/S63 turbo and non-turbo V8 used in 545i/550i, 645ci/650i, 745Li/750Li, X5, and X6. It's also used in the S55 turbo 6-cylinder used in the F87 M2 Competition, F80 M3, F82 M4, G87 M2, G80 M3, G82 M4.

Your engine's thermostat regulates coolant flow and temperature in the cooling system. When open it allows hot 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 system is drawn from your heater core. Modern cars are much more complex and have computer-controlled cooling strategies to regulate various temperature systems in the car, which makes the thermostat a more critical piece.

This is a Genuine BMW thermostat with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
