My 04 grand prix supercharged is leaking coolant?
I was told its a freeze plug? Its leaking from the
front under the headers like once you dump water
in it goes right back out any ideas please the car
runs and sounds great besides the over heat
Yep sounds like a freeze plug, only way to fix it is too replace it, and if one is bad the others might also be very weak. And yes it is not a very cheap or easy job to replace them.
You should also NOT be driving it like this, you're losing most of your coolant and engine overheating will soon turn this motor into a boat anchor.
Although the location sounds wrong, the plastic elbows that take coolant to the heater core are prone to breakage and will dump coolant faster than you can replace it. Before you rip into the engine check them as well as hoses etc. Sometimes coolant sprays out and appears to be originating in a different place than it really is. In any event, Ken is right. Other than starting it up for a few minutes to move it around you should not be driving it at all. Overheating it will wreck the engine in very short order.
