Review on πŸ”§ OEM Wahler 4326.97D: BMW Engine Coolant Thermostat Kit with Housing, Sensor, and Gasket by Noah Lewis

Revainrating 1 out of 5

6 months failed.

The thermostat worked for 6 months, after which it failed. I've noticed the coolant temp go from the usual 96F to over 100F. Upon inspection, the thermostat housing found a leak at the pin. See photo with coolant residue just below the pin. Very disappointed that an OEM part can fail so quickly. Now it will hurt me to replace it again.

Pros
  • New
Cons
  • Crumpled packaging
