I just recently flushed my 1986 BMW coolant, and it drained a hair under eight quarts of antifreeze. Then when i refilled it with the bleeder screw loosened up it would only take about 6 quarts of antifreeze.I drained the engine block; the radiator,and the car is suppsed to take over eleven quarts of antifreeze. My heater stopped working about a year ago it will only blow hot air out of the top dash area/and warm air always comes out of it. A leak also popped up under my passenger side door(today), but only when i pour antifreeze into the coolant reservoir.

The reason that i performed the flush was due to my temp. gauge reading low,then going slightly to the high side at stoplights.I have replaced the hoses,belts,water pump, water pump housing and themostat all with in the last year.Do you think that it might be a clogged/now leaking heater core.
