Review on AISIN THT-018 Thermostat: Efficient Temperature Control for Optimal Performance by Rolando Munoz

Revainrating 1 out of 5

That does not work. Overheated.

I replaced my water pump and thought it would be a good idea to replace the thermostat while I'm at it. The new one never opened which caused my 4runner 90 pickup to overheat. I exchanged it for the old one and everything was fine again. I must have gotten a bad one. Professional mechanic double checked and confirmed.

Pros
  • critical aspect of cooling system
Cons
  • not sure
