greekguy7 Posted August 28, 2007 Report Share Posted August 28, 2007 Wife just got home after a long drive in 90 degree heat and noticed it was leaking coolant from the overflow tank when she parked it. I opened the hood and the overflow reservoir was all the way to the top! It was at the proper level the other day. After waiting 15 minutes, I restarted it and the reservoir tank completely emptied into the radiator but I noticed the upper radiator hose was being sucked/collapsed closed unitl I shut her off. The hose was not collapsed when I originally opened the hood and noticed the coolant was all the way to the top of the reservoir. Any ideas besides the thermostat stuck closed?? THANKS!!

1990lumina Posted August 28, 2007 Report Share Posted August 28, 2007 Which engine? I'd recommend thermostat replacement just for cheap assurance before going on further, though on my 3.1 thermostat was simple to change and was like $5 in parts..

xtremerevolution Posted August 29, 2007 Report Share Posted August 29, 2007 I'm not sure about the coolant hose, but I know in my regal, my radiator cap had gotten messed up and it also caused my coolant to overflow out of the reservior. I would suggest replacing that radiator cap first. Quote Link to comment Share on other sites More sharing options...
