ANSWER: Hi Curtis:

What model and engine is this car? If you tell me that I can give you a better idea of waht the issue is. It's just going to be a guess though without seeing the car it's hard to say but a few of our cars have different issues with leaking coolant and I can give you a better Idea of wher to look.

QUESTION: i'm sorry i forgot to give you the model and engine size,the is a 96 grand prix,the engine is a 3.5

Answer
Hi.
Okay there is either a 3.1 LITER OR A 3.4 LITER AND IT MAKES A DIFFERENCE. If it's a 3.1 I'd look at either a water pump ower intake manifold gasket or a head gasket. If it's a 3.4 the same things to look for except for the lower intake manifold gasket. It's more than likely a 3.1 with a lower intake maifold gasket leaking out the rear of the manifold and running down the block and dripping off the starter motor.
