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.

I own a 2003 Dodge Durango. The coolant fan stopped working. I found a plug loose near the fan. Is it possible it came unplugged? If yes, then is the plug inside the fan case? I have looked all over and...


I couldn't find the plug or wire on the diagram on my online resource, either. The fan must have a cable going to it to operate, somehow, though, I agree.
