Where are the best locations to look for a potential coolant leak? WHen I add coolant with the engine running and the heater on, the heat comes pouring out of the vents. But soon the joy ends as no more heat comes out. This is usually in a few hours.

Best thing to do is have a shop pressure test the cooling system and they can determine exactly where its leaking and give you a estimate to repair this before further damage to the engine occurs and you can find a shop near you here www.repairpal.com/directory
