i know the oem thermostats operating temp. is at 180 F but i recently replaced it w/ an 170 F, but instead of staying at 170 F at normal operating temp, it goes up to 185 F or so...can this be a defective thermostat? btw when i installed the new one i did notice that it wasn't a tight fit as the original one but i don't think that would be the problem. i can tell the temp b/c i have a Autometer temp. sensor sandwiched between the radiator hose.
