Make sure the thermostat is new and it opens up when hot, you can do that by submerging it into a pot of boiling water for a while and you will see it opening up, if it doesn't then is bad. Also, make sure that the coolant (or antifreeze, depending where you live of course) is not brownish or "muddy" like, this would mean that oil is mixing with your coolant which could mean that you have a blown head gasket and needs to be replaced. If you see the "muddy" looking like coolant, then it is very likely you have a blown head gasket. You can do it yourself, is a looooong job and it takes a lot of patience, but it can be done. If you don't feel comfortable doing it then get it done by someone that is going to really get ALL the gaskets replaced, not only the ones on top of the cylinder heads, and that they charge you fair. The whole gasket set can run between $150 and $500 depending on the car, but the head gaskets alone can run between $60 and $150, depending on the car of course. Read about your car before you go to a mechanic, it will save you a lot of headaches and extra expenses.

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.

    Antifreeze is not circulating through radiator. Radiator is new - 2 months old. Also, no heat and fast idle.


    Problem is not your radiator--unfortunate for you. It's more likely the water pump. The water pump pumps the water around through your radiator to be cooled and then through the engine block to cool your motor. Before you go tearing the water pump out though, you may want to check to see if your fan belt is in good condition and working properly because the water pump works off of the fan belt turning the pulley to pump the water around. If the fan belt is off that pulley, it may need to be put back on or re-routed correctly to start pumping the water.

    Then if that is not your problem, the water pump will probably need to be replaced. I believe it can be accessed from underneath the engine compartment, but first you will have to take the tension off the fan belt and remove the belt, then loosen the bolts around the front of the water pump. Put a catch pan under the car though because all your water/antifreeze will come gushing out. That water pump should be available at your local AutoZone or another auto parts store for around $100.

    My car is overheating and i need to know how to put in the water pump?


    Is the water pump leaking coolant? If not, then why do you think it's bad?

    If the engine is overheating, there are several other things to look at before you consider the replacing the water pump.

    Are the fans electric motor driven, or fan belt driven? If fan belt driven, replace the fan clutch. If electric motor driven, check the fan control module and/or fan motors to make sure all is good there. Fan control module tend to fail in weird ways, so if nothing is wrong with the motors, replace the module.

    Always, always, replace a thermostat that has overheated. Once overheated, they consistently fail. Make sure you properly refill the radiator with coolant after the stat is changed.

    Check that the bottom radiator hose does not collapse.

    Check the radiator for corrosion. Boil the radiator out, or have it done, or replace the radiator.

    Changing the water pump on 2000 Jeep Grand Cherokee V6


    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.
    Drain cooling system. Refer to Draining Cooling System in this group.
    Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

    The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using special tool spanner wrench 6958 with adapter pins 8346 and a suitable fan wrench loosen the fan drive Viscous Fan and Fan Drive Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
    WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094) SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

    CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter.

    If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
    Remove two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware Do not attempt to remove fan shroud at this time.
    Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
    After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
    Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic belt tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front) Automatic Belt Tensioner - When all belt tension has been relaxed, remove accessory drive belt.
    Remove lower radiator hose clamp and remove lower hose at water pump.
    Remove seven water pump mounting bolts and one stud bolt
    CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

    Remove water pump and gasket. Discard gasket.
    INSTALLATION
    Clean gasket mating surfaces.
    Using a new gasket, position water pump and install mounting bolts as shown. Water Pump Installation - Tighten water pump mounting bolts to 54 N·m (40 ft. lbs.) torque.
    Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
    Connect radiator lower hose to water pump.
    Relax tension from belt tensioner Automatic Belt Tensioner - Install drive belt
    CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Belt Routing for correct belt routing. Or, refer to the Belt Routing Label located in the engine compartment. The correct belt with correct length must be used.

    Position fan shroud and fan blade/viscous fan drive assembly to vehicle as a complete unit.
    Be sure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
    Install two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware
    Be sure of at least 25 mm (1.0 inches) between tips of fan blades and fan shroud.
    Install fan blade/viscous fan drive assembly to water pump shaft.
    Fill cooling system. Refer to Refilling the Cooling System in this group.
    Connect negative battery cable.
    Start and warm the engine. Check for leaks
