Hi! I was wondering if anyone could give me some advice. 96' Honda Civic: It over heats and has no heat in the heater! It only over heats when idling at a stop. While driving it cools down but there is still no heat. Things I have done: I replaced the thermostat which was actually broken inside. The metal had torn off on one side so I replaced it. Now that it is replaced the car has heat for arund 30 seconds and then goes to a mediocre tempreture that is not hot at all. Before there was no initial heat. It didnt seem to fix anything though. The upper radiator hose gets hot. The fans come on. I dont feel much of anything in the lower radiator hose. Should I check the coolant for 50/50 mix? Weak Water Pump??? I would take it to the dealer but I have no trust in my local dealer.
