meltboy1 Posted July 28, 2008 Report Share Posted July 28, 2008 89 Grand Prix 5spd Well I was drivin to school today and I noticed I had no power steering and when I look down and see that my temp is pegged... so I pull over, couldn't have driven on it for more than a couple min I think. Pop the hood, and just as I thought, my belt snapped. I call a friend and she brings me a new one, I put it on and drive home, which it did fine, I put about 40 miles on it since this happened. But the bad is that hose that goes from the water pump area to the heater core, well it was a small leak before, but after getting heated up it's leaking a lot worse now and I need to fix this. I got inside and popped off some of the lower dash and took out the glove box, but I just can't find this hose as it comes into the car, and GM and their infinite wisdom made it one piece the whole way instead of a fitting outside the firewall... Anyone have any insight on this or maybe can scan me a page or 2 out of the haynes book so I don't have to go buy another one. I lost my damn book.

Crazy K Posted July 28, 2008 Report Share Posted July 28, 2008 the heater core return line. CAP IT! It's summer time! j/k. that metal line typically rots. many people replace it or patch it using rubber 5/8" heater hose. usually you will see the leak is somewhere where one of the tabs was welded on, cut back on both side of the leak and bridge with heater hose, and clamps.

meltboy1 Posted July 28, 2008 Author Report Share Posted July 28, 2008 Awsome, I was thinking of doing just that, but I was afraid it may not be an option. The leak is right past the 90* bend that leads it towards the firewall. I would have bought 1/2 inch though, glad you told me it was 5/8...

GOT2B GM Posted July 28, 2008 Report Share Posted July 28, 2008 I swear it was 3/4 hose, take a sample of the pipe with you. My cutty leaked in the same spot, as long as you don't kink the hose around that bend its all good. Quote Link to comment Share on other sites More sharing options...
meltboy1 Posted July 28, 2008 Author Report Share Posted July 28, 2008 ya, I will probably cut it near the firewall and make it rubber from there to the pump. Quote Link to comment Share on other sites More sharing options...
