One of the pulleys on the belt will be a tensioner. Its a smaller one, second one down on the left i think? Whichever one it is with a spanner on the hex in the middle you should be able to move the tensioner up or down to free off the belt. The pumps arent too difficult to do BUT they do break up and then you have a problem. There should be two threaded holes in the casing of the old one put in m8 or m6 bolts, whichever fits, and you should be able to pull the pump out like that. Make sure to be taping the block around the pump though while trying to pull it out to help it out because when the lugs with the threaded holes break, you have one big problemo.

Testimonial: "the advice is right on. Got the belt off.Unfortunately I already broke one of the lugs with the threaded hole. have to figure out a different way."

What must be removed to replace the water pump on a 1998 bmw 528i?


Not much really. I did my son's on the road in 20 degree weather. Remove the fan nut 1.250" wrench...left handed thread with the special tool. Remove fan, and shroud at the same time. Remove belly pan so you can drain the radiator. 16mm socket and 1/2 socket wrench to move the idler pulley tensioner. You move it not remove it. You move it enough to release serpentine tension. Remove belt. and 4 bolts holding the water pump pulley. Now the water pump is exposed. remove the bolts or nuts holding it in. go get some 6mm x 30mm hex bolts and use them to pry out evenly the water pump. That's it. reassemble, don't forget the o-ring.

Changing the water pump on 2000 Jeep Grand Cherokee V6


WATER PUMP
The water pump is bolted directly to the engine timing chain case/cover.

A gasket is used as a seal between the water pump and timing chain case/cover.

If water pump is replaced because of bearing/shaft damage, or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

The water pump can be removed without discharging the air conditioning system (if equipped)

REMOVAL
Disconnect negative battery cable from battery.
Drain cooling system. Refer to Draining Cooling System in this group.
Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using special tool spanner wrench 6958 with adapter pins 8346 and a suitable fan wrench loosen the fan drive Viscous Fan and Fan Drive Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
