My 1999 Monte Carlo stated leaking antifreeze dips at a time. Then the next thing I know there was puddles of anti-freeze under my car. I took the car to a shop and the mechanic said I needed a intake manifold gasket and that's going to be $450. I didn't have the money so I had the car pushed home and now I am waiting to get the car fixed when I can come up with the money.

My 1999 Chevrolet Monte Carlo ls, engine 3100 V-6, has needed a particularly expensive repair twice. This repair was to fix a coolant leak near/on the intake manifold gasket. The first repair (at 52,000 miles) was done under warranty, the second (at 90,000 miles) was done at a local service station because the car was no longer under warranty. With this problem, the coolant leaks out fairly quickly, and could cause an engine fire if the engine gets too hot, also the coolant is flammable. This problem was the subject of a recall of several GM models with 2000 to 2002 model year cars (Chevy, Pontiac, etc) with the 3100 and 3800 engine models. However, the 1999 models have not been recalled, and my car with I know many others have the same problems with the same engine parts as the 2000 to 2002 model year cars. I paid the second repair at my own expense of approximately $825. I have called Chevrolet and they have denied any reimbursement for my expenses incurred for the repair. Is there any other way I can ssek to have the repair reimbursed" in any case, shouldn't the recall affect the 1999 or previous models"

At 59-60K miles my intake manifold gasket is 'seeping' according to the Chevrolet dealer, my water pump is also seeping - $750 to fix - I find a major problem at 60K miles unbelieveable, the water pump, sure, but the intake manifold gasket? I had a second opinion formed by 2 other mechanics who have both seen the same problem in the same engine (3.1L) w/this car - shouldn't Chevy do something?
