what i did was use some printer ink "yellow" and put it in my radiator. its water soluble and then ran it for a day and i found the leak at the water pump bearing im not shure where yours might be but this will help you locate it. hope this helps. take care.
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.
If you notice any free play in the shaft or the pulley, you will need to take the pump apart and replace the bearings.
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.
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
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.
Disconnect the car battery. This will prevent the electrical fan from turning on while you are under the hood.
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.
Remove the fan assembly. This will include the shroud, the fan and the fan belt. Disconnect the electrical leads for the fan.
Remove the pulley for the fan belt as well in order to have access to the water pump.
Use a socket set to remove the water pump from its engine mount.
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.
Reassemble the cooling system by replacing the water pump,
pulley, fan belt, fan assembly and radiator hoses. Refill the radiator
with the fluid.
Start the engine to see if the water pump repair was successful. Check for leaks before you take the car out on the road.
3.3 AND3.8 ENGINES TAKE OFF SERPENTINE BELT 15MM ON BELT TENSIONER . REMOVE 2 HOSES OFF PUMP. 5 ?BOLTS AROUND WATER PUMP. IT WILL COME OFF WITH ANTIFREEZE LEAKING OUT. HAVE DRAIN PAN UNDER . ALSO IT IS GOOD TIME TO CHANGE THE LOWER HOSES. REINSTALL WITH NEW GASKET, FILL SYSTEM, PUT HEAT ON HOT AND RUN UNTIL THERMOSTATE OPENS, AND CHECK FOR LEAKS, TORQUE IF NESSESARY ( ENGINE OFF)!!REFILL AT SIDE TANK
The water pump can be removed and installed without discharging the air conditioning system (if equipped).
Disconnect battery negative cable.
Drain cooling system. Refer to Draining and Filling found under Cooling System, Service and Repair.
Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse. 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.
Remove upper radiator hose clamp and hose at radiator.
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. A Snap-On 36 MM Fan Wrench (number SP346 from Snap-On Cummins Diesel Tool Set number 2017DSP) can be used. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating. Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
6. If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
Remove fan shroud attaching hardware (two bolts at bottom-two clips at top).
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.
Do not remove water pump pulley bolts at this time.
Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front). When all belt tension has been relaxed, remove accessory drive belt.
12. Remove four water pump pulley-to-water pump hub bolts and remove pulley from vehicle.
Remove lower radiator hose clamp and remove lower hose at water pump.
Remove heater hose clamp and heater hose from heater hose coolant return tube.
Loosen heater hose coolant return tube mounting bolt and remove tube from water pump. Discard the old tube O-ring.
Remove seven water pump mounting bolts.
Loosen clamp at water pump end of bypass hose. Slip bypass hose from water pump while removing pump from vehicle. Discard old gasket. CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.
Clean gasket mating surfaces.
Using a new gasket, install water pump to engine as follows: Guide water pump nipple into bypass hose as pump is being installed. Install water pump bolts. Tighten water pump mounting bolts to 40 Nm (30 ft. lbs.) torque.
Position bypass hose clamp to bypass hose.
Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
Install a new O-ring to the heater hose coolant return tube. Coat the new O-ring with antifreeze before installation.
Install coolant return tube and its mounting bolt to engine. Be sure the slot in tube bracket is bottomed to mounting bolt. This will properly position return tube.
Connect radiator lower hose to water pump.
Connect heater hose and hose clamp to coolant return tube.
Install water pump pulley. Tighten bolts to 27 Nm (20 ft. lbs.) torque. Place a bar or screwdriver between water pump pulley bolts to prevent pulley from rotating.
Relax tension from belt tensioner. Install accessory drive belt.
CAUTION: When installing the serpentine accessory drive belt, the belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Illustration above for correct belt routing. 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.
Install fan shroud.
Install fan blade/viscous fan drive assembly to water pump shaft.
Standing on the passenger side of the car with the hood open looking down into the engine bay you will see the serpentine belt. If you have air conditioning, look directly below the air compressor pulley, the next one down is the water pump. Another easy way to find it is to find the lower radiator hose (again on the passenger side of the engine) and follow it to the engine block, the pulley where the hose meets the block is the water pump (not the pulley, but what the pulley spins is the pump).
It is not complicated, depending on what hands-on level of DIY on car. Here are what need to do, so you can estimate how easy or hard when you look through your engine.
Drain all the coolant, remove the thermostat housing, remove the fan, belt. Remove the water pump pulley. There are 4 bolts to hold the water pump in place.If you think you can take them out and put them in without removing the AC compressor then you can do it. I did it twice without removing the AC. The pump was fine for the second time, but for leaking seal. At dealer, it is easier to access from the bottom since they have a lifter. But it is doable at home. Have fun if you decide to do it.
so i just replaced my water pump today on the same car, mine is a 5.9 magnum. I drained the whole system before i started working on it, next you have to take off the fan, if you look on the inner side of the fan there is a big nut there, in order to loosen that i put to bolts into the holes on the water pump pulley and used a thin screwdriver for leverage, while putting pressure on that, i loosened the nut, be careful not to slip cuz those fan blades are dangerous. but once you have removed that nut from the pulley take out the four bolts holding on the housing, pull the fan and the housing out at the same time. next remove the belt, after that is done, disconnect the hoses from the water pump, there are three, one on each side and one on top. there are a total of eight bolts holding the pump on, keep track of them because they are different sizes. But that is how i removed mine. It was all farely simple i am a girl and i managed to do it so i think you should be fine. Hope it works for you becuase it didnt work for me, i now think that it is my head leaking, if you know anything about that let me know.
