Into 3rd hour. 2 lower Car Motor mount bolts just are not budging WD-40 is all I have to loosen the bolts, worked for the top 2, but I got to use the 1/2" drive on them, 3/8" driver is all that fits on the lower bolts (with the help of a large box end wrench for leverage!) if/when I do get them, will I need a breaker bar to get the engine mount bolts out?

- jack vehicle up and place axle stands under the frame (or where it states in your owners manual, to place axle stands under your vehicle)

- use a 2" x 4" board long enough to span a couple inches over the front to back (or side to side - depending on if your engine is side mount or front mount) of engine oil pan

- loosen engine mount bolts

- place the 2" x 4" on the hydraulic jack and jack it up slowly until it touches the oil pan and make sure the 2" x 4" doesn't get snagged on anything (such as the frame)

- remove engine mount bolts (making sure the jack (and 2" x 4" board) are holding the weight of the engine before removing eng. mount bolts

- jack it up until the engine raises enough for the water pump to clear

Replacing serpentine accessory belt. Is it necessary to remove motor mounting brace to remove and install new serpentine belt?
From my understanding I think you have to remove the motor mount and mount the engine to remove it because I have been asking different mechanics about the serpintine belt on my 1998 Buick Lasabre.

How hard is it to change the water pump on my 1991 Buick Regal 3.8 engine. It is not leaking but car keeps getting hot, I have changed the radiator
The pump is not that hard to change but if you haven't tried a new thermostat yet then i would suggest that you try that first,it is the most common cause of overheating problems,next being the rad fan it's self not coming on either because of a bad motor or a temperature sensor failure or a defective relay.Let me know what you have eliminated and we can go on from there.

How do i replace a water pump on a 1992 buick lesabre custom
GM Bonneville/Eighty Eight/LeSabre 1986-1999 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 of this repair guide.
On some engines, removing the alternator provides better clearance for removing the water pump. For alternator removal and installation procedures, please refer toin this repair guide.

  1. Unfasten the water pump pulley bolts, (long bolt removed through access hole provided in the body side rail), then remove the pulley.
  1. Disconnect the radiator and heater hoses from water pump.
  1. 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.

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.
  1. 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.
To install:
  1. Apply a suitable sealant to the bolt threads.
  1. Position a new gasket, then install the water pump to the engine and tighten the retaining bolts, as follows:
  1. For 1987-94 vehicles, tighten the long bolts to 29 ft. lbs. (17 Nm) and the short bolts to 97 inch lbs. (11 Nm).
  2. 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.

  1. For 1992-95 vehicles, install the torque axis mount, as follows:
    1. Attach the torque axis engine mount bracket assembly to the front of the engine using the 2 bolts and nut.
    2. 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.
    3. Tighten the 2 lower bolts that were previously loosened on the torque axis engine mount.
    4. Adjust the engine height to align the torque mount with the torque axis mount bracket.
    5. 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.
  2. Install the water pump pulley and secure with the retaining bolts.
  3. Connect the radiator and heater hoses to the water pump.
  4. Install the serpentine drive belt.
  5. Connect the negative battery cable.
  6. 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.

1992 Buick LeSabre - Water Pump Bolts Near Engine Mount.
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

Water pump, replacement directions
you will need to drop the motor mount at the top of the engine over the pump to get it off. other than that it is straight forward. when you remove the bolt from the mount be sure to chase it with a rod to hold the mount up or put a jack under the engine to support and aid in instalation.

Fan Belt replacement
Sort of, look at the belt closely before you remove it to make sure the belt is not looped through the motor mount. On some makes there is a motor mount that is attached to the sidewall of the vehicle and this mount must be removed to remove and reinstall the belt, otherwise, yes it is that simple. Make sure you know how the belt goes back on. There should be a diagram under the hood for the belt routing. Or you can grab a sheet of paper and draw it yourself. If you do attempt to change it and the motor mount must be removed, you have to support the engine weight with a jack before removing the mount. Be careful and please let me know if this was helpful.
