'92 929 3.0 V6 A/T 122K sat for a few months undriven, and now it has no heat. The temp gauge goes a little above half way in the norm. range, but the bottom hose isn't getting hot, like the thermostat is not opening. Replaced the thermostat last night to no avail....The gauge goes up between half and the upper part of the normal range, but there's still no heat, and the lower radiator hose does not warm up at all. The top hose gets hot as hell, and eventually the coolant burps back out the top of the radiator cap opening....I've been squeezing both upper and lower hoses with the cap off and the car running to try to bleed it, until it gets hot enough for the coolant to start coming out, but it isn't working. Is there a bleeder somewhere I am missing, or some trick to get this cooling system to circulate right? I am thinking water pump..maybe..but it seems to be circulating, just air locking at the bottom hose/thermostat.
PLEASE HELP!!!!
