Review on Motorcraft RH167 Thermostat Housing by William Rothstein

Revainrating 5 out of 5

Use original Motorcraft parts for this repair!

It is best to use OEM Motorcraft parts to assemble this thermostat housing. The original lasted 75,000 miles and was replaced by a Dorman build that lasted 7,000 miles in less than 10 months. All new Motorcraft body plus new o-ring #8 (#8) for temp sensor, no leaks since install 3 weeks ago or more.

Pros
  • Maximum Performance
Cons
  • Some Difficulties
