    I have a 1991 Plymouth Acclaim 2.5 and the heater is not blowing hot and
    there is bubbles in the cooling system. The Head gasket has been in place
    for about 4 years and I am wondering if it had gone bad again. other
    symptoms are rough Idle and lowered fuel efficiency, the problem continued
    even after I replaced the thermostat.I have not had a chance to pressure
    test the cyl's yet but that is slated for this Thursday providing that I can
    find my tester. The Engine has Overheated a few times, and I am wondering if
    it is time to have my spare head rebuilt and install it.
    Any thoughts are welcomed.

    Bad News! Your head gasket may have failed again. The symptoms you state are
    classic of a burnt head gasket. Do a compression and pressure test just to be
    100% sure. As far as the heat goes, you will need to power backflush the heater
    core. If that does not work replace it.

  3. Bubbles in coolant and no heat...blown head gasket. No heat
    because you have an air bubble that is keeping coolant from
    getting to the heater core. The head on the car may be
    okay, but if you have a good spare and can just yank the one
    and put on the other, good. Be sure the new head is checked
    for warpage and check the block's mating surface for flat.
    I recommend using a Mopar Performance head gasket. I have
    not had good luck with FelPro and other aftermarket brands.
    Also recommend new head bolts just to be safe.
