Pontiac Thermostat Housing Review

I am very happy with it. Normally, whatever thermostat housing I use, my radiator hose goes into my valve cover vent. I use tall valve covers because of the roller rockers and a slightly larger breather, and even a small one goes straight in so I avoid that.

Pros
  • Engine Cooling & Climate Control
Cons
  • Reliability
