Review on MotoRad 2023-192 Engine Coolant Thermostat: Optimal Temperature Regulation for Enhanced Engine Performance by James Gregg

Revainrating 5 out of 5

Performance Thermostat for Ford 351C, 351M and 400 Engines

This motorcycle thermostat is a replacement part for Ford 351C, 351M and 400 engines. The center bore is 0.2" larger than the Stant thermostat that I removed from his 351C engine. This motorcycle thermostat model has the added feature of a wobble pin on the outer flange to help release air pockets and equalize pressure. Build quality is very good The specified opening temperature is 192 degrees Fahrenheit, which is slightly lower than the 195 degrees found on most stock Ford 351C engine thermostats.

Pros
  • Great Price
Cons
  • Compatibility
