Re: How to replace the water pump on a 1992 geo tracker...
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
spring.
-
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.

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.
-
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.
To install:
-
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).
-
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.
Hope helps (remember comment and rated this).
