I suspect the water pump needs replacement, since there is liquid like fluid below engine. what are the steps one must take, to replace the water pump. Why is it not simple to do? Looks like alot of...


1.3L & 1.6L Engines
  1. Remove the timing belt cover, timing belt, tensioner, plate and spring.
  2. Remove the water pump mounting bolts.
  3. 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.
  4. If necessary for clearance, remove the oil level dipstick tube retaining bolt from the engine block and the alternator adjusting brace.

WARNING

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.


  1. 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.

  1. Thoroughly clean the water pump gasket mating surfaces of old gasket material and corrosion.

The drive belt can be used to hold the fan stable while loosening the mounting fasteners
90883pg2.jpg

Loosen the fan bolts, then either remove the drive belt before the fan and shroud ...
90883pg4.jpg

... or wait to remove the belt, along with the water pump pulley
90883pg5.jpg

Once the cooling fan and shroud are removed, access can be gained to many of the engine components, including the water pump

To install:

  1. 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 Nm).
  2. 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.
90883g43.gif

Be sure to install the two rubber seals between the water pump, oil pump and cylinder head before installing the timing belt cover-1.3L and 1.6L TFI engines
90883g42.gif

The 1.6L MFI engine uses only one rubber seal between the oil pump and water pump

  1. If removed, install the alternator adjusting brace and the oil level dipstick retaining

Water pump removal


Water Pump REMOVAL & INSTALLATION CAUTION
Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old. 1.8L Engine
  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the timing belt.
  4. Raise and safely support the vehicle.
  5. Remove the engine oil dipstick tube bracket bolt(s) from the water pump.
  6. Remove the two bolts and the gasket from the water inlet pipe.
  7. Remove all but the uppermost water pump mounting bolt.
  8. Lower the vehicle.
  9. Remove the remaining bolts and the water pump assembly.
  10. If the water pump is being reused, remove all gasket material from the water pump.
  11. Remove all gasket material from the engine block. Fig. 1: Exploded view of a water pump mounting - 1.8L engine 86753048.gif
    To install:

  16. Install a new gasket onto the water inlet pipe.
  17. Install the two bolts from the water inlet pipe to the water pump and tighten to 14-19 ft. lbs. (19-25 Nm).
  18. Install the bolt to the engine oil dipstick tube bracket.
  19. Lower the vehicle.
  20. Install the timing belt.
  21. Fill the cooling system.
  22. Connect the negative battery cable.

    Fig. 7: Use a scraper to clean the mating surfaces of the cylinder block and water pump 90983p50.jpg
    To install:
  13. Make sure the mating surfaces of the cylinder block and water pump are clean and free of gasket material.
  14. If the water pump is to be replaced, transfer the timing belt tensioner components to the new water pump.

How to replace the water pump on a 1992 geo tracker 1.6 liter engine


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

  1. Remove the timing belt cover, timing belt, tensioner, plate and spring.
  2. Remove the water pump mounting bolts.
  3. 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.
  4. If necessary for clearance, remove the oil level dipstick tube retaining bolt from the engine block and the alternator adjusting brace.

Fig. 1: Exploded view of the water pump mounting

WARNING 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.
  1. 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.
  1. Thoroughly clean the water pump gasket mating surfaces of old gasket material and corrosion.
To install:
  1. 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 Nm).
  2. 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.
