Question -
ok, my car keeps overheating and i added antifreeze but it keeps draining somewhere.  there is no leak, ive dumped three gallons of antifreeze in the expansion tank and nothing is spilling anywhere.  also there is smoke comming out of the a/c vents.  please let me know how to fix this problem.

Answer -
Nick,
Check the heater core. See if the floor in the front is wet with anti freeze. The core is all the way in front on top of the "hump".

Answer
Nick,
Pull the under dash panels off on both sides and get to the heater core and and remove it and replace it with a new one. This job is not too tough so if you are good with your hand and have the tools and patients you can get it done in a few hours.
