Pontiac Grand Am Water Pump Q. Hi, Where on a 1989 Pontiac Grand Am LE 2.5 liter engine code "U" is the water pump located and how difficult is it to change? Thanks...

A. It's on the passenger side of the engine where the belt is. The belt needs to come off as does the pulley that is bolted to the pump. Coolant needs to be drained into a pan to be reused or disposed of properly. The pump is held onto the engine with four bolts, near the lower radiator hose. Good luck!

REMOVAL:

1. Disconnect battery ground cable, then drain cooling system.
2. Remove drive belts.
3. Remove water pump attaching bolts, then remove water pump from cover assembly, Fig. 15.
4. If installing a new pump use the pulley from the old unit.

INSTALLATION:

1. Apply a 1/8 inch bead of red RTV sealant or equivalent, on the water pump sealing surface.
2. Coat water pump bolts with RTV sealant to avoid coolant leaks.
3. While the sealant is still wet, install the pump and torque bolts to 25 ft. lbs.
4. Install drive belts, then fill cooling system and connect battery ground cable.
5. Inspect cooling system for leaks.
