Question about Pontiac Grand Prix
My girlfriend's car, 98 pontiac grand prix 3100, didn't have heat and went overheated. I thought it was water pump that was leaking but I ended up found out it is leaking from belt tensioner area right under the alternator. Is there an coolant connector there?

more than likely one of your heater hoses has sprung a leak ... if your car is not over heating with water in it than your water pump is fine.... the gasket around it may need to be replaced tho ... start your car then you look for your leak please get back to me

The power steering pump is dead center on the top of the motor. If your standing on the passenger side the water pump is the next pulley to the right. The serpentine belt will go over the power steering pulley, under the water pump pulley, and then around the a/c compressor.

These engines like the 3.8 usually have a intake leaking problem. Also the have plastic elbows on the passengers side of intake that go to heater hoses can leak also. Is it a 3.8 liter engine in your car. And where abouts does the fluid look like its coming from.

I would start at my coolant hoses there is one on the rt side of the car check coolant overflow hose and the bottle check heater hoses as well or it might be that the pump isn't sealed or something could be left loose

Park the Pontiac in a safe work area and open the hood.
Inspect the top of the black plastic cover that surrounds the fan for the serpentine belt routing diagram. This diagram has the instructions for installing the new serpentine belt around the accessory pulleys.
Inspect the front of the engine and locate the automatic belt tensioner. The tensioner on the 1999 Pontiac model vehicles is located between the alternator and the crankshaft pulley. The tensioner has a pulley on one end with a bolt head in the center of the pulley. Use the bolt head to rotate the tensioner.
Turn the tensioner counterclockwise with the breaker bar and a metric socket. Pull the belt out from under the tensioner pulley with your other hand. Then, slowly let the tensioner retract until it stops.
Pull the belt out of the other remaining pulleys. Then, pull the belt out of the engine bay and lay it on the ground.
Route the new belt around the crankshaft pulley. Then, route the new belt around the other remaining pullleys by using the serpentine belt routing diagram for instructions.
Rotate the tensioner pulley counterclockwise with the breaker bar and socket. Then, slide the new belt under the tensioner pulley. Slowly let the tensioner retract until it stops. The tensioner pulls all of the slack out of the belt and brings the new belt to the proper tension. Remove the breaker bar and socket from the tensioner pulley.
Inspect the new belt to ensure that it is seated inside of all the accessory pulleys as directed by the diagram. Then, crank the engine and allow it to run for about 15 seconds. Turn the engine off. Inspect the belt again once more to ensure that
the belt is still around each pulley. Close the hood.
