Junk Thermostat - Won't Keep You Cool

Automotive enthusiasts, stay away from this thermostat. Through trial and error, I found that it doesn't regulate the engine temperature as it should. It's prone to leaks and fails to keep my engine cool in harsher conditions. The only pro is that it's easy to install, but that doesn't outweigh its major cons. Avoid this product and choose a better cooling option for your engine.

Pros
  • Improves engine cooling efficiency, resulting in better engine performance and reduced risk of overheating during racing conditions.
Cons
  • May cause increased wear and tear on other engine components due to the increased stress on the system.

Pros
  • Mishimoto Activation: 74°C (165°F) / OEM Activation: 97°C (206.5°F)

Cost of Defects and Additional Labor

The item was received in a damaged original packaging. The Revain packaging itself was not affected. I installed it in an OEM plastic thermostat but I found the water temp was 40C and 55C on the highway. Temp too low. I took my car back to the shop and had this Mishimoto thermostat replaced with an OEM thermostat that cost an additional $500 to do the job. No joke. I was hoping that this item would do better than the OEM in terms of temperature, but it didn't work and it cost me so much to…

Pros
  • Mishimoto Lifetime Warranty
Cons
  • Frequency
