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.

You need the 3 essentials for proper engine operation.Fuel,spark,and compression.You said the fuel pump is working but the question remains;is fuel reaching the fuel rail.Try starting the car and then take one spark plug out and check it for fuel odor.
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 During these procedures, identify all components removed from the
engine so that they may be reinstalled in their original positions. If
discarding the old components so that new components can be installed,
identifying the old items is not necessary.
1.3L and 1.6L Engines
Remove the timing belt cover, timing belt, tensioner, plate and
Remove the water pump mounting bolts.
Remove the one (1.6L MFI engines) or two (1.3L and 1.6L TFI
engines) small rubber seals from between the water pump and the oil
pump, and the water pump and the cylinder head.
If necessary for clearance, remove the oil level dipstick tube
retaining bolt from the engine block and the alternator adjusting brace.

Do NOT use a prybar between the water pump housing and the engine
block to separate the two components; this can cause scratches and/or
gouges, which can prevent proper sealing.
Pull the water pump off of the engine block. If the water pump is
difficult to remove from the engine block, use a soft-faced mallet to
tap the water pump housing until it loosens.
Do not disassemble the water pump; if the water pump is damaged or
defective, the entire unit is replaced.
Thoroughly clean the water pump gasket mating surfaces of old
gasket material and corrosion.
Along with a new gasket, install the water pump on the engine
block. Tighten the water pump mounting bolts to 88-115 inch lbs. (10-13
On 1.3L and TFI 1.6L engines, install two new rubber seals: one
between the water pump and oil pump, and the other between the water
pump and the cylinder head. The MFI 1.6L engines only use one rubber
seal, located between the water and oil pumps.
If removed, install the alternator adjusting brace and the oil
level dipstick retaining bolt.
Install the timing belt, tensioner, plate, spring and cover.
there is a hole in the pulley for the power steering unit. That hole accesses the bolts to drop this unit down and then you can change the water pump. The trick is getting these two bolts lined back up to reinstall it
Your local library will have a service manual, check it out or make copies of the pages if it's reference only. This is one of the the easiest water pumps to replace. A good technician can do the job in 20 minutes or so. The basics are:
Remove belt Remove 4pulley bolts and pulley remove 4 larger water pump bolts. (coolant will run out of these holes, so, have a drain pan to catch it.) remove the remaining smaller perimeter bolts pop pump off engine with screw driver carefully remove old gasket from engine surface with razor blade, do not gouge the aluminum surface! install new pump and gasket use pipe sealant on the 4 longer blots reinstall belt add coolant to radiator test drive/check for 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.
