Ok, as you all may know, i have been having some major overheating problems. I kind of turned my eye at first to the fact that it might be a head gasket leak, because i * really * diddnt want it to be that. But, i am at the stage now, where, its either the water pump, the sensor or the head gasket blown. Because i keep getting irratic readings. Whats the easyiest way to check for a head gasket leak? Someone said there was a kit you could buy, for the parts store etc. Its either the impeler on the waterpump is rotten, the sensor is bad, or the thermostat i replaced is not working. Theres only a few things left IMO i changed just about everything on the cooling system alredy.
