SmokesGTP Posted January 7, 2004 Report Share Posted January 7, 2004 I get home today for lunch and after eating I go outside and notice my car is leaking a steady stream of coolant from near the back of the engine compartment on the passenger side. All the hoses seem fine and the water pump is also not leaking. Could this be the metal hose that runs down beneath the overflow? It seems to be coming from near there but I wouldn't think it would all of a sudden spring a leak like this. My dad said because it's under pressure it would probably just leak out very fast like this. If you guys think this is the problem how do I go about fixing this? It looks like a royal pain in the ass. Quote Link to comment Share on other sites More sharing options...
Whiskey River Posted January 7, 2004 Report Share Posted January 7, 2004 Mine did something very similar and it turned out to be the heater core. On my Lumina, there is a drain that funnels the coolant out the firewall when the core pops. Quote Link to comment Share on other sites More sharing options...
topless94style Posted January 7, 2004 Report Share Posted January 7, 2004 Yea i would check the heater core thats what it sounds like. If the heater core is draining, you probably need a new one. Quote Link to comment Share on other sites More sharing options...
zachismisit Posted January 7, 2004 Report Share Posted January 7, 2004 Hmmm, is the heater core right behind or near the dash on passengers side in 95 olds cutlass? Quote Link to comment Share on other sites More sharing options...
topless94style Posted January 8, 2004 Report Share Posted January 8, 2004 That would be my guess, but truely i dont know. Quote Link to comment Share on other sites More sharing options...
cutlsp Posted January 8, 2004 Report Share Posted January 8, 2004 i think it is buried under the dash man sure its easy to replace after you take apart the dash board i'm a master at it now since i have swaped interiors about 2 times already but it sounds like your heater core craped out man oh and on my 88 its more towards the center of the car but on yours i'm sure its some were in the passenger compartment under the dash Quote Link to comment Share on other sites More sharing options...

SmokesGTP Posted January 9, 2004 Author Report Share Posted January 9, 2004 Trust me the intake gasket couldn't leak like this, it was pouring. Quote Link to comment Share on other sites More sharing options...
brian89gp Posted January 9, 2004 Report Share Posted January 9, 2004 more then likely the heater core return pipe. Take the passenger wheel off and feel for holes, its right there at the bottom of the frame rail. Quote Link to comment Share on other sites More sharing options...
Baddflash Posted January 9, 2004 Report Share Posted January 9, 2004 I agree HC return pipe, look for rust spots along frame rail. That's what it was on mine and it just did it all of the sudden. Quote Link to comment Share on other sites More sharing options...
