Review on Dorman 902-033 Engine Coolant Thermostat Housing Assembly: OE FIX for Chevrolet Models - Optimize Performance and Reliability by Fort Steffen

Revainrating 1 out of 5

Production stopped!

At first glance this product looks 100% better than the factory. It turned out to be an old and newlywed throttle body hose. I replaced it, started the car until warm and noticed coolant leaking from under the thermostat housing. It's too late to return now!

Pros
  • Fail Safe Design - Improved to prevent factory cracking Small diameter tubing and shallow seal groove
Cons
  • Nothing here
