Works better than the cheap oem plastic ones. Engine is running much cooler.

In 2019 I had to replace my coolant thermostat on my jeep wrangler 2012. I went with plastic replacement because I didn't know there was an aluminum replacement available. My coolant thermostat started leaking early this year, so I decided to go with aluminum replacement. I'm glad that I did. When I drive my jeep it feels different in a good way. I feel like the performance is better.

Great upgrade. Way better than the plastic thermostat housing.

Looks and works great

If you know cars, you will see almost all parts now a days are made of plastic. When you add in heat/cold effects that is not a lasting combination as the plastic can brittle and split at source locations like this. Replaced the OEM plastic when I flushed the coolant system and very pleased I did. There was already a fracture starting from the factory over tightening one of the mounting bolts so was just a matter of time. Great quality solid metal disaster part that fit perfectly!

Better than the OEM.

Excellent quality definitely better that the plastic OEM thermostat. I installed it a week ago on my 2017 Jeep Wrangler Unlimited and so far so good. I will update if anything changes.

Very easy to install and only took me about 20 minutes to do everything (after watching YouTube videos on installation). It fit perfectly and it seems to be a good quality product.
