Description

If you own a M52tu, or a M54 BMW engine, you have likely had issues with the plastic thermostat housing. Unlike the 6 cylinder engines previously, BMW decided to do a one piece thermostat, housing and sensor unit.  Because of the extreme heat conditions inside the engine bay, the thermostat housing can crack and leave you stranded.  Our aluminum thermostat housing replacement is completely plug and play. It features an all aluminum design, with a brand new thermostat and sensor.  This is the perfect upgrade to your faulty cooling system. 

Replaces OEM BMW PN 11531436823,11531437040

*Note: Includes gasket, thermostat, and sensor. Thermostat is not removable.
