Review on Dorman 902-3010 Engine Coolant Thermostat Housing: High-Performance, Reliable and Top-Quality by Russell Robertson

Revainrating 3 out of 5

Screw spacing and external dimensions? Appears to be different from the original.

The stock thermostat housing on my '89 Jeep had more clearance on the exhaust hose (which goes to the heater core) than this one. This will fit but needs to be pressed against the adjacent heater hose before tightening which is not required on the originals.

Pros
  • Engine Cooling & Air Conditioning
Cons
  • No Automatic
