Replaced on my 2001 Suburban
I order this thermostat to replace the one on my 2001 suburban. I replace the radiator with a new 3 core all aluminum radiator and thought I would put in a 180 degree thermostat to replace the 195 degree thermostat that comes from the factory because I use this vehicle mainly for towing. There is no way to know if you are actually getting a 180 degree thermostat because there are no markings on it to confirm the degrees. After installing it, it appears that it is really a 195 degree thermostat.

Does NOT Fit
This does not fit my 2005 Chevy Silverado 4.3 V6. The product says it will fit. This is another item from X AUTOHAUX that says it will fit when it does not.
