No I didn't do the headgasket myself. I took it to a mechanic and he sent it to a machine shop and they said the cylinder head was fine. My heater works fine, I think, you can't really feel it until you turn the knob up to 3 or 4.
My needle went past 3/4 (almost to the red) last time it overheated ( didn't turn on heater to test the new fan clutch).
How do you bleed the system?
