gjgogol Posted November 24, 2014 Report Share Posted November 24, 2014 i purchased a thermostat for my 2002 cad deville dhs and they sold me one rated at 180 degrees. my manual states thermostat should start opening at 188 degrees and be fully open at 206 degrees. will the 180 thermostat hurt my engine? what thermostat should i be using?
