RE: Heat problem
My coolant tank has stress fractures in it, which is being replaced tomorrow.Right nowmy heat is non-existant in this cold weather. Trying to keep the antifreeze/coolant level up by refilling it. Heater only runs when I'm on the highway 50pmh or more. Runs cold when driving locally. Once coolant tank is replaced, will this fix my heater problem?

RE: Heat problem
Maguar, sounds like you might have this problem (I just cross-posted it on the other thread from today).

Coolant leak: Coolant loss from broken expansion tank bleed tube could lead to overheating. (2002-06)

I'm surprised they have to replace the whole expansion tank. Can't they just replace the bleed tube?

RE: Heat problem
General heater diagnosis. First off it has been between -10 and -20 F here for the last few days, don't expect your heater to produce the same amount of heat output as if it were +20.
Make sure the system is full, heat that flucuates when you rev the engine or drive at high speeds can indicate extreme cold, or an air pocket in the system, primarily the heater core. It can also indicate a sticking open t-stat or restricted heater core. You can check the t-stat and heater corewith an infrared heat sensing gun by checking inlet and outlet temps. If you have high mileage either could be the cause though t-stats on the Xs are much more common than heater core problems.

RE: Heat problem
Hey Real_Tech:
elsewhere in one of these threads you gave some really good tips on how to make sure your coolant is full, with no air bubbles, etc.
I would think that would make a VERY USEFUL FAQ.
Ansd I could sure use the tips myself, since I can't seem to find that thread right now.
