Remove Water Pump grand am 3.1

Your Cabrio has one of several 2.0L Volkswagen engines - determine your engine type from the
8th digit of your VIN, which will be either an "A", or "C",both are 2.0L engines.

Volkswagen 2.0L engines offered in 2001:
(a) 2.0L (Aba) Engine
(b) 2.0L (Aeg/Avh/Azg/Bdc/Bev/Bgd) Engine
(c) 2.0L (Aeg/Avh/Azg/Bdf) Engine

For completeness, I've included the water pump maintenance manual entries for all (3) 2.0L VW
engines offered in 2001. Note that the instructions below include (3) illustrations, which are
reproduced faithfully from the manual, but the last (2) illustrations are identical, since the last two
engines in the list above are virtually identical.

Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

this isnt a solution,just a suggestion.my husband,a fairly skilled home mechanic,recently did this.it took 12 hours over a 2 day period.you have to remove everything from the front of the motor,including the motor mounts,to access the pump.make sure you change the timing belt at the same time if it shows ANY signs of wear so you aren't doing the procedure again anytime soon..good luck!!

Water Pump REMOVAL & INSTALLATION CAUTION
When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old. 1987-95 Vehicles EXCEPT 1995 VIN 1 ENGINE

1. Disconnect the negative battery cable.
2. Drain cooling system into a suitable container.
3. Remove the serpentine drive belt, as outlined in Section 1 of this manual. NOTE: On some engines, removing the alternator provides better clearance for removing the water pump. For alternator removal and installation procedures, please refer to Section 2 of this manual. Fig. 1: After removing the alternator, remove the brace
   
   
4. Unfasten the water pump pulley bolts, (long bolt removed through access hole provided in the body side rail), then remove the pulley. Fig. 2: Pull the water pump pulley from the pump
   
   
5. Disconnect the radiator and heater hoses from water pump. Fig. 3: Use a screwdriver to loosen the hose clamp screws, then disconnect the hoses from the water pump
   
   
6. For 1992-95 vehicles, remove the torque axis mount, as follows:
   1. Use a suitable engine support fixture and lifting bracket to raise the engine slightly to take the weight off of the engine mounts.
   2. Remove the through-bolt from the torque axis (front) engine mount.
   3. Lift the engine with the support fixture until the power steering reservoir touches the strut tower cross brace.
   4. Loosen the bottom two bolts on the torque axis (front) engine mount.
   5. Remove the A/C line clip and top two bolts on the torque axis engine mount, then remove the mount.
   6. Remove the 2 bolts and nut attaching the engine torque axis mount bracket assembly to the front of the engine. NOTE: On some engines, when you remove the 13mm bolts, coolant will flow from the bolt holes, so make sure to position a drain pan under the pump before unfastening the bolts.
      
7. Remove the water pump attaching bolts, then remove the water pump from the vehicle. Remove and discard the gasket. Thoroughly clean the gasket mating surfaces. Fig. 4: Unfasten the water pump mounting bolts (see arrows for locations of top bolts) . . .

Hope this help (remember comment and rated this).

I'm not sure what motor you have in that Buick, but my wife's 92 Old's water pump went out and I had a heck of a time with the bottom two bolts. I talked to a mechanic and he told me to put a piece of wood on top of a floor jack, slide it under the oil pan and lift the motor off it's mounts to gain easier access ,and after I did, with a lot of patience I got the job done.(About 2 hours, a 1/4 turn a a time) I hope this helps

alfred11s: No, you don't have to lift the motor. You do have to remove the right hand engine mounting insulator.
I will give you the procedure for the removal to access the pump:.
1.Drain engine coolant
2. remove right hand engine mounting insulator
3. Remove #2 and # 3 timing belt covers
4. Remove front engine mounting insulator as follows
a. remove hole cover
b. remove the 2 bolts from the mounting
c. remove the nut, the through-bolt and front engine mounting insulator
5. Remove the electric cooling fan
6.Disconnect engine wire remove the bolt and 2 nuts and disconnect the engine wire.
Water pump removal instructions:
1. Disconnect the crank sensor connector from the dipstick tube
2, Remove the dipstick tube and dipstick (only 1 bolt holds it)
3. Disconnect the water temp sensor from harness
4, Remove the two nuts and the # 2 water inlet from the hose.
5.Remove the three bolts which retain the water pump!
CAUTION! try to keep antifreeze off the timing belt. Put rags down and pack them where the coolant would normally spill.
WELL alfred11s: My answer should be a pleasant surprise.
Print it out and carry it out to the car.
If I've done well, maybe you can comment on what you think

JUST COMPLETED THIS JOB TODAY. MAKE SURE THE ENGINE HAS COOLED DOWN . IT TOOK APPROX 2 1/2 HRS. DISCONNECT THE NEGATIVE POST ON THE BATTERY. JACK UP PASSENGER SIDE FRONT AND SUPPORT ON JACK STANDS. REMOVE PASS. FROUNT TIRE. DRAIN RADIATOR INTO CONTAINER FOR PROPER DISPOSAL OR REUSE. USING FLOOR JACK PROVIDE SLIGHT TENSION ON OIL PAN WITH A SHORT 2 X 4 WOOD PIECE TO PROTECT OIL PAN. LOOSEN 3 ENGINE MOUNT BOLTS ON PASS. SIDE OF ENGINE COMPARTMENT. ALLOW APPROX 1" BETWEEN SHOULDER OF BOLTS AND MOUNT. LOWER ENGINE UNTILL BOLTS ARE SET ONTO MOUNT. REMOVE ENGINE SPLASH SHIELD INSIDE WHEEL WELL OF REMOVED TIRE. LOCATE WATER PUMP AND LOOSEN 3 PULLEY MOUNTING BOLTS (THIS IS WHILE BELT IS ON PULLEY) REMOVE SURPENTINE BELT AND CONTINUE TO FULLY REMOVE THE PUMP PULLEY. IT WONT COME OUT AS THE PUMP & PULLEY HAVE TO COME OUT TOGEATHER. REMOVE 5 WATER PUMP BOLTS AND CAREFULLY WORK WATER PUMP OUT BETWEEN THE ENGINE AND VEHICLE FRAME. CLEAN ALL MATING/GASKET SURFACES AND BOLTS. USING A SMALL AMOUNT OF TACKY SEALENT TO INSURE THE NEW WATER PUMP SEAL STAYS IN PLACE, THE INSTALL IS PRITTY MUCH THE REVERSAL OF REMOVAL.

GOOD LUCK, REMEMBER TO TIGHTEN ALL BOLTS TO MFR SPECS AND BLEED THE AIR OUT OF THE COOLANT AS REQUIRED.
