says hot coolant temp and there is no heat. please help i love this car and dont want to
give it up.
Did you replace the coolant temperature sensor. If the sensor is shorted internally the computer will "think" the coolant is hot. Also check the wiring going to the sensor. If it's damaged a bare spot on the wire(s) may be touching something metal. Same deal. You MAY have 2 sensors for this. One sensor for the gauge on the dash, if equipped, and one for the computer. If you have a temperature gauge on the dash is it reading correctly or is it pinned on hot? HTH. -Jim
Did you make sure you got all the air out of the cooling system after replacing the above listed items?
