Coolant Leak in 99 Grand Prix.....Help!!!!
I had a coolant leak at the manifold intake gasket, which I guess is common in the 3.1 engine. I got this fixed. When they were fixing it they found another leak at the "timing". What is that? And does it have anything to do with the water pump? I am still leaking coolant but wondering if changing the thermostat could help, we think its part of the problem?
