this is what dexcool does when it sits. ive never personally seen it until today. 99 monte carlo 3.8
my plan is to dig as much as i can around the neck out. unhook both upper and lower rad hoses, and run water through it. after that hook up the lower rad hose, take t stat out, stick water hose in the rad filler neck and let the pump run clean water through the system for a while. hopefully that will get alot of that crap out of there. the car has never overheated. enven the last 2days after sitting for three months. later replace the lim gasket in both the monte (brothers car) and grand prix (my car)
he had to go somewhere tonight, hopefully one more night of driving it wont hurt it. (i know i woulnt drive it)
