It's probably your heater core.tessamarie said:Oil is clear. Now what?
yeah, hadn't thought of that. That gave Dewd fits for months.Punxsy Stang said:Is all of the air out of the cooling system ? Maybe it just needs the air blead out . If their is a air pocket in the system it will cause the car to over heat as well . Just loosen the bleader nut and run the car . When no more air bubbles comes out it should be fine . good luck .
If it was installed wrongly, it can impede flow, without cutting it off, the effect is still the same.hawks05 said:i could be wrong but im pretty sure that even if the theromstat is closed the coolant should be getting to the heater core other wise major pressure would be building up in a system that doesnt allow any flow yet the water pump us pumping especially when you first start driving and it hasnt open up and you are going say 35mph. also another way to just check to see if the themostat is working right you should notice flow in the radiator once the car gets up to normal running temp.
yeah, but at 90,000 miles?hawks05 said:true but im just saying that i believe the delivery to the heater core is a by-pass so that when the thermostat isnt open the coolant still moves just not through the radiator. now if your not getting heat when you turn on the heat then your heater core is mostlikely blocked. i mean there could even be a slight chance that your water pump is messed up too.
