Review on 🌑️ Stant-14147 OE Stainless Steel Thermostat by Harald Patterson

Revainrating 4 out of 5

Says it will fit 2011 Sub Impreza but nowhere near OEM

I got this while changing a timing belt/water pump. Had to stay with the OEM. This fits, but is 1/3 smaller than the original. The main reason for head gasket failure is a faulty thermostat. I couldn't risk it and had to go to Subaru to get a new one.

Pros
  • Best
Cons
  • So far so good
