Great Cooling Upgrade for My Car!

This aftermarket coolant thermostat certainly did the job on my automotive cooling system! As my tests showed, it keeps the engine running at the optimal temperature and prevents overheating even during hot summer days. The installation process was easy and straightforward, making it a great DIY project for those looking for a quick upgrade. However, be sure to double-check the compatibility with your specific vehicle model before purchasing. Highly recommend!

Pros
  • Great cooling performance, easy installation
Cons
  • Compatibility may be limited to certain car models

It has worked well so far

I purchased this thermostat on March 19, 2016. So far it has worked great. At the first start the thermostat starts to stick. To be honest I think a thermostat should last more than a year.

Pros
  • Premium Professional Replacement Coolant Thermostat
Cons
  • ---

Replacement thermostat

Radiator flushed and hoses replaced, thermostat needs replacing. I was surprised when the thermostat came with no gasket. I figured out the worst case, go to an auto parts store and buy it. The old thermostat worked fine, but since I changed the antifreeze and hoses I figured it made sense to replace the thermostat. When I took out the old thermostat it had a rubber gasket that fit around the lip of the thermostat, the gasket was in good condition so I reused it. No leaks yet, happy camper.

Pros
  • Fits, shapes and performs as expected
Cons
  • No instructions
