ok so i just bought the car and im having this lil problem i got the car and the thermostat guage didnt work so i replaced the cooling temp sending unit the lil 1 wire one and the guage started working and now iv noticed that the car stays cool when driving it but when u come to some lights the car starts to get hot now i unplugged the rad fan thermostat switch and jumped the plug and the fans kick on so i figured the sensor was just bad so i replaced it still having the same issue the fan do cut on its just by then its almost 3/4 of the way up on the temp guage im rackin my brain and i have nothing unless one of the 2 sensors i have replaced new is bad the rad switch or the temp guage sending unit
