Review on Efficient Engine Protection: MotoRad 7456-187 187°F Fail-Safe Thermostat for Optimal Performance by Michael Jenkins

Revainrating 5 out of 5

Motorad 7456-187 Failsafe Thermostat, 187°F

My problem is solved. The water pump I ordered/installed last year came with a faulty thermostat. The Delco AC box will have a Motorad manufactured thermostat but no failover function. Used in 2005 GM SUV with 6.0L Vortec engine.

Pros
  • Thermostats
Cons
  • Damaged
