I was told today during my trip to the parts store for my cooling issue that the "Stop Leak" stuff that these stores sell are only good for temporary fixes so you can make it to the Auto Shop but not for much longer. The coolant many times needs to be flushed from the system prior to use and this warning isnt too big on the back of the little bottles.
The reason its only temporary is that the chemical that stops the leaks gets clogged in the heater core. If it gets clogged then the unit itself could overheat and malfunction or cause smoke in the cabin.
Hopefully this helps you out. I ask myself the 'why me' question all the time.
I've drivin my car 200,000 miles and still haven't found the light at the end of my tunnel.
Good Luck
