BMW thermostats are known to fail, but luckily they typically fail wide open - meaning that your car can still cool. We offer thermostats from various OE suppliers we trust along with upgraded motorsport specific thermostats where applicable to make sure your BMW stays cool on track.
Don't take chances! Proper maintenance is required to keep your BMW performing at peak levels. The thermostat basically controls when your car will overheat. The sensor on the housing is also used by the engine computer to set the fuel mapping on the engine. A faulty sensor or thermostat will lead to the engine running rich (too much fuel). This thermostat fits BMW E39 540i 99-03 E38 740i 99-01 X5 4.4i 4.6is 99-2003 with M62 engine.
