Having problems with your 1991 Suzuki Sidekick ?

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 parts have to be removed first, just to get to the water pump. Tony

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. \015\012Pull 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. \015\012Thoroughly 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

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

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

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. \015\012Along 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. \015\012
  3. \015\012On 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.

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

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


  1. \015\012If removed, install the alternator adjusting brace and the oil level dipstick retaining
Its about a 3 hour job at a professional shop. and it is a do it right or damage the engine kind of job. you will be replacing the timing belt also .so if you are going to tackle it i would recommend you buy a manual to guide you through it.
