I have 2 questions..I'm about to change the water pump in my Olds 88..There are 2 bolts that go thru the engine mount into the water pump..but there is no clearance to fit a ratchet into the bottom bolt cause of the mount..Is there a special tool to use? Also do you have to jack the engine and remove the mount to take off the water pump?It is a 1994 olds 88 with a 3800 engine.Your help in this matter would be greatly appreciated..thx
I just did mine, and you do need to support the engine and remove the mount, or atleast remove the half attached to body of car, and slide the mount out of the bolts way. Slide a jack under the oil pan with wood covering jack so the oil pan does not get damaged.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Air pump/Smog pump and Compressor go on first, on the shaft.
Power steering goes on next
Altenator is the last one.
After market pulleys and the above mentioned parts may change this order..

yes you do. place a floor jack under engine with a block of wood on top of jack to protect the engine, put just enough pressure on jack to steady engine. remove motor mount, then jack up engine a bit to take belt off. replace the belt then lower jack and attach the mount. on the mount only the outside bolts need to come off to raise engine. do not remove from engine side unless you are changing it or its bad, be carefull when raising engine, pick it up from a sturdy place, not the oil pan. have a good day !!
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
Disconnect the negative battery cable.
Drain cooling system into a suitable container.
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
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
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
For 1992-95 vehicles, remove the torque axis mount, as follows:
Use a suitable engine support fixture and lifting bracket to raise the engine slightly to take the weight off of the engine mounts.
Remove the through-bolt from the torque axis (front) engine mount.
Lift the engine with the support fixture until the power steering reservoir touches the strut tower cross brace.
Loosen the bottom two bolts on the torque axis (front) engine mount.
Remove the A/C line clip and top two bolts on the torque axis engine mount, then remove the mount.
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.
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. 5: . . . then remove the water pump from the engine
Fig. 6: Use a gasket scraper to carefully clean the water pump's mating surface
Fig. 7: You can also use Scotchbrite® or equivalent non-abrasive scouring pad to clean the water pump gasket mating surface
Fig. 8: When using a scraper to clean the gasket mating surfaces, be careful not to gouge the engine and cause leaks

Apply a suitable sealant to the bolt threads.
Fig. 10: Coat the bolt threads with a suitable sealing compound
Position a new gasket, then install the water pump to the engine and tighten the retaining bolts, as follows:
Fig. 11: Place a new gasket on the water pump mounting surface
For 1987-94 vehicles, tighten the long bolts to 29 ft. lbs. (39 Nm) and the short bolts to 97 inch lbs. (11 Nm).
For 1995 vehicles, tighten the water pump-to-block bolts to 22 ft. lbs. (30 Nm) and the water pump-to-front cover bolts to 11 ft. lbs. (15 Nm), plus an additional 80°rotation.
For 1992-95 vehicles, install the torque axis mount, as follows:
Attach the torque axis engine mount bracket assembly to the front of the engine using the 2 bolts and nut.
Fig. 12: Install the torque axis engine mount bracket and secure with the 2 bolts and nut
Replace the 2 upper bolts previously removed from the torque axis engine mount, and attach the mount and plastic clip for the A/C lines.
Tighten the 2 lower bolts that were previously loosened on the torque axis engine mount.
Fig. 13: Exploded view of the torque axis engine mount and tightening specifications
Adjust the engine height to align the torque mount with the torque axis mount bracket.
Insert the through-bolt, attach the retaining nut and tighten to the specifications shown in the accompanying figure. Remove the engine support and lifting fixture.
Fig. 14: Insert the torque axis mount bracket through-bolt
Install the water pump pulley and secure with the retaining bolts.
Connect the radiator and heater hoses to the water pump.
Install the serpentine drive belt.
Connect the negative battery cable.
Fill cooling system and check for leaks. Start the engine and allow to come to normal operating temperature. Check for leaks and top-off the coolant.
Your starter location is shown below with arrows pointing to the 2 mounting bolts. Note the position of the wires on the solenoid and remove the wires first, then the starter bolts. If there are any shims as shown in second photo, please put them back with the new starter. If you have any questions, please let me know.
Removal 1. Support the vehicle on jack stands. 2. Disconnect the negative battery cable. 3. Drain the cooling system. 4. Remove water pump drive belt. 5. Disconnect the coolant hoses at the water pump. 6. Remove the water pump pulley bolts (long bolt removed through the access hole provided in the body side rail), then remove the pulley. 7. Remove the torque axis mount. See TORQUE AXIS ENGINE MOUNT . 8. Remove the water pump attaching bolts and pump. 9. Clean all gasket mating surfaces.
Installation 1. Using a new gasket, install the water pump on the engine. Tighten the bolts to specifications. See TORQUE SPECIFICATIONS . 2. Install the torque axis mount. See TORQUE AXIS ENGINE MOUNT . 3. Install the water pump pulley, then tighten the bolts to specifications. See TORQUE SPECIFICATIONS . 4. Connect the coolant hoses onto the pump. 5. Install the water pump drive belt. 6. Fill the cooling system. 7. Add coolant supplement tablets. 8. Connect the battery cable, then start the engine. 9. Inspect for coolant leaks.
First you must drain the coolant. Remove powersteering pump[keep hoses connected)this is just to make room for water pump removal so just sit it off to he side.Loosen the the water pump pulley mounting bolts, remove the drivebelt,remove the pump pulley. Remove the pump mounting bolts and pul the pump from engine.Install every thing in reverse ,but be sure to clean the mating surface of old sealer and gasket first, also be sure to use RTV gasket sealer on engine side of the new gasket.Be sure not to over/under tighten the bolts the torque specs. are 22 to 29 for the long bolts and 96 to132 for short bolts and 108 to 132 ft lb for the pulley bolts.
