I have a 97 Acieva that I bought a couple of years ago to drive back and forth to the base to save gas, but it has sat parked for about 3/4 of that time do to a coolent leak that I haven't been able to track down. I've deployed overseas and come back during that time though so it wasn't all wasted time. The symptoms are that I get a whiff of hot antifreeze peridically, and while it doesn't occur every time i drive the car, I usually get a few drops of coolant on the driveway when it cools off over night. The really confusing part is that this cycle of events will go on for days or even weeks, and then one day I back out of the driveway and there will be a puddle about 15" across of coolant that has dripped from the car and the Low Collant light will be on. The resevoir is always low or empty when that happens. It appears that TSB 676204 may address the isue but not sure about that yet. The last time this happened I tried to chase the drips a little while laying on the driveway. The liquid seems to be running down the back side of the block, and dripping off of that crossover tube that runs under the block. Could this be a freeze plug that is seeping? What about that crossover tube? Peterson AFB has a lift in their auto hobby shop so I can get it up on one to work if I need to. I'm leaving for Iraq in about 3 weeks and would like to try and fix this before I go so that the wife won't have to be hassled with refiling the coolant during the winter months. I'm really puzzled by the fact that I can go days at a time with just a few drops here and there, and then all of a sudden the next day there will be a relatively LARGE puddle. Thanks in advance to any wrench jockies out there that might have any ideas on this one.
