Fit my 1995 K1500 perfectly and works great. However this is the 180 degree model. My pickup needs a 195 degree thermostat. My own mistake and happily purchasing the correct one I need.

When I got back into working on cars as a hobby in retirement I looked for familiar names for parts . Stant was always my first choice back in the day and I was not disappointed. This was an exact replacement and is working well and was a good price.

Great quality as expected from a well established company. Opened at the correct temperature and keeps the engine at just the right running temp.

50 years as a mechanic and I still swear by Stant thermostats you buy cheap you damage an engine instead of saving money
