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.

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 !!

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 89633p01.jpg

  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 89633p03.jpg

  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 89633p02.jpg

  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) . . . 89633p04.jpg
    Fig. 5: . . . then remove the water pump from the engine 89633p05.jpg
    Fig. 6: Use a gasket scraper to carefully clean the water pump's mating surface 89633p06.jpg
    Fig. 7: You can also use Scotchbrite® or equivalent non-abrasive scouring pad to clean the water pump gasket mating surface 89633p07.jpg
    Fig. 8: When using a scraper to clean the gasket mating surfaces, be careful not to gouge the engine and cause leaks 89633p10.jpg
    Fig. 9: Exploded view of the water pump mounting - 1994 vehicle shown, others similar 89633g37.gif
    To install:
  8. Apply a suitable sealant to the bolt threads. Fig. 10: Coat the bolt threads with a suitable sealing compound 89633p09.jpg

  9. 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 89633p08.jpg
    1. For 1987-94 vehicles, tighten the long bolts to 29 ft. lbs. (39 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.
  10. 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. Fig. 12: Install the torque axis engine mount bracket and secure with the 2 bolts and nut 89633g34.gif

    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. Fig. 13: Exploded view of the torque axis engine mount and tightening specifications 89633g35.gif

    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. Fig. 14: Insert the torque axis mount bracket through-bolt 89633g36.gif

  11. Install the water pump pulley and secure with the retaining bolts.
  12. Connect the radiator and heater hoses to the water pump.
  13. Install the serpentine drive belt.
  14. Connect the negative battery cable.
  15. 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.

How do I remove oil pump pulley to replace the water pump?

If you mean the power steering pump, it will have to be removed to access the bolt. It's just 2 bolts. You get them through the holes in the power steering pump. Just unbolt it and push it aside.
