1990 Grand Am - coolant leak

Have a 1990 Pontiac Grand Am, automatic trans, 2.3 liter 4 cylinder engine, 2 door, 113,000 miles.

Have a coolant leak. Water comes out as fast as you put it in. Looking from the front of the car, the leak is at the back of the engine compartment, at the bottom, a little left of center. Leak is from what looks like a hose connection approx 1/2" dia. Have looked for a loose hose and find none. Also cannot see where a hose would connect anywhere else on the engine.

Have looked up info on the Grand Am using alldata.com but cannot determine what is leaking. I donot know what to look for.

Would you have any idea what is leaking?

Thanks
Lee Blanton

That's where your water pump is located.

Desi is correct and there is also a pipe that bolts to the water pump housig that may be leaking.Best bet is put it on jackstands and see where it's coming from for sure.

1990 Grand AM

Have gone under the car and looked at the leak. Leak is not from anything attached to the engine. There is a tube extending from the bulkhead separating the engine and passenger compartments. Water leaks out of this tube as soon as I add water to the radiator. Could this have something to do with the heater core?
