Flushing worked! Now it's TOO hot! LOL
I had an hour to spare today, and decided -- what the hey -- I'll try flushing out the heater core since I was under the hood replacing the tensioning pulley anyway. Can't say that I took it all that seriously, either; didn't use radiator flush and didn't have the nerve to use the Lime-Away than another poster suggested.
So, for better or worse, all I did was disconnect the pair of heater bypass hoses at the point where they intersected the water pump (plugging the lines to the block) and ran moderately high water up through the lines first in one direction and then the other. A fair amount of sludge came out, but it was hardly an ah-ha moment.
I re-buttoned everything, turned on the heat (this morning I had it set at 90 degrees and it barely reached room temperature) and POW! I coulda roasted hot dogs on the dash vents, and actually felt uncomfortably warm. What a difference!
This will be a wonderful change when it snows this weekend. No more sitting in the driveway waiting half an hour for a tiny space to defrost so I can see the road.
Next summer I'll do the complete flush and really clean things up. Thanks for all the good advice, guysl
