Re: Problem with 91 grand prix

Have you visually seen it coming out of the engine block or is it just leaking on the passanger side. The drain for the heater core is no the passanger side of the vehicle and it is located on the firewall. A leak here looks like it is coming from the engine. Check it out as it may be a fairly easy and inexpensive fix vs repairs to the engine itself. If it is the manifold gaskets keep an eye on the oil as when these gaskets go bad they will cause water to get in the oil and damage the bearings thus ruining the entire engine.

The gasket will be $5-600 at a garage, you can do it yourself for around $50 if you have the time an tools to do the job.

Before jumping to conclusions find out exactly where the leak is coming from. PS it could also be coming from the water pump!!
