It is a bit easier to remove the fan clutch nuts with the belt on but if you have it off already it still is the same procedure. Once you remove the upper shroud half (I think there are 5 small bolts) you will have more room to work with. Start draining the coolant out of the pitcock in the bottom of the radiator and remove the radiator cap. There are 4 nuts holding the fan clutch on to the 4 pulley studs. Take along flat head screwdriver and place it so you are able to pry against 2 of the nuts so you can lock the pulley in place while you loosen the nuts with a closed end (boxed end) wrench. Use the screwdriver to spin the pulley when you are ready to loosen another nut. Be careful to keep your hand on the fan when it is ready to be removed or it may damage the radiator. Do the same thing in reverse when you are ready to install it.

Water Pump leaks from the front end of the Wagon.


follow this steps and fix it. God bless you
  1. Determine the Reason for Water Pump Failure
    • 1 Repair a water pump by checking your car for a failure in the bearings. You can test for bearing failure by seeing if there is any play in the shaft that is connected to the electrical fan blades, as well as the drive pulley to the pump itself.
    • 2 If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.


    • 3 Determine if the water pump failure is due to a leak in the casing. Examine the water pump housing for leaking or water stains in the drainage hole next to the pulley.
    • 4 If water is dripping from this hole, then the seals inside the pump need to replaced in order to repair the pump.
    Remove the Water Pump for Repair
    • 5 Allow the engine to cool completely before removing any part of the cooling system. Never open a radiator cap or plug while the engine is still warm.
    • 6 Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
    • 7 Drain the radiator of all fluid and disconnect the radiator hoses. Collect the fluid with a plastic container and keep it in a safe place until you are ready to put it back into the radiator.
    • 8 Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
    • 9 Remove the pulley for the fan belt as well in order to have access to the water pump.
    • 10 Use a socket set to remove the water pump from its engine mount.
    • 11 Open the housing for the water pump and replace the seals or bearing as necessary. Some auto parts stores carry repair kits that have both the seals and bearings for specific types of water pumps.
    • 12 Reassemble the cooling system by replacing the water pump, pulley, fan belt, fan assembly and radiator hoses. Refill the radiator with the fluid.
    • 13 Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.

Replacing water pump


To replace water pump on Chevrolet s-10. You need take of the top half of the fan shroud, pop off the hoses to the water pump and the take out the bolts to the water pump.To get the fan off, you need a special tool called a half h tool, The half H tool holds the bolts in place so you have leverage to then twist the fan off.Before removing parts to replace water pump first drain the antifreeze.Place the drain pan under the radiator, open the drain on the bottom of the radiator and allow the antifreeze to drain into the pan.Remove the upper fan shroud using a 10-mm socket. Remove the four 13-mm nuts securing the radiator fan to the water pump pulley, using a wrench.Pull the water pump pulley off the water pump. Remove all hoses from the water pump, including the lower radiator hose and upper heater hoses. Remove the four bolts securing the water pump to the block, using a 15-mm socket and ratchet with the 3-inch extension. lift the water pump off the block. Clean all the remaining gasket material off the block passages using the gasket scraper. Lay the new water pump face down with the outlet ports up.And complete the procedure of fitting the new water pump in reverse of how you removed the old one.---------------- Thank you.

WATER PUMP
The water pump is bolted directly to the engine timing chain case/cover.

A gasket is used as a seal between the water pump and timing chain case/cover.

If water pump is replaced because of bearing/shaft damage, or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

The water pump can be removed without discharging the air conditioning system (if equipped)

REMOVAL
Disconnect negative battery cable from battery.
