Review on 🔧 Dorman 902-800 Engine Coolant Thermostat Housing Assembly for Top Models by Shane Schobinger

Revainrating 1 out of 5

Junk from China: Thermostat housing

Installed on a 2003 Trailblazer, never worked! The thermostat has not opened, the coolant level is normal. The engine tried to warm up, I had to turn it off, the temperature rose to 230+. Mechanical felt tubes, the top tube will burn your hand. The hose from the thermostat section was slightly warm. The mechanic said the thermostat was faulty. So, another $225 down the drain. So I bought AC Delco. So far perfect. Don't waste your money on this, it's a POS.

Pros
  • Handsfree
Cons
  • Very expensive
