  Q: What Are the Key Inspection Points and Steps for Water Pump Replacement on Jeep Cherokee?

  A:

  While exchanging the water pump, check the Fan Blades and viscous fan drive closely, since vibration may have caused damage that should be fixed. Removing a water pump is safe on models with air conditioning and all engines use a reversed rotating pump which is easy to recognize by the letter R on the back of the impeller. The water pump impeller is attached to the rear of the pump shaft and bearing assembly and the pump is only opened for service as one fully assembled unit. Removing the water pump from a 2.5L engine requires first disconnecting the negative battery terminal, draining the refrigerant, removing the upper Radiator hose, loosening the four fan hub-to-water pump pulley nuts without removing them and finally removing the accessory Drive Belt. If your car has an electric cooling fan, remove its connector, unhook the fan shroud and take out the four nuts to get the fan and shroud out altogether. After you have removed the fan blade and viscous fan drive, be sure not to put the viscous fan drive horizontal when you store it. After that, unbolt the Power Steering Pump and bracket, purge the water pump pipe of radiator and heater hoses and unscrew the four mounting bolts, reminding yourself that one of the bolts is longer than the rest before you remove the pump from the vehicle. Should you have to replace the pump, first remove the heater hose fitting, making sure to remember how it was fitted. When replacing a pump, join the heater hose pipe to the pump with Mopar Thread Sealant With Teflon, make certain the gasket mating surfaces are clean and closely inspect them for any signs of damage or erosion. With the gasket's silicone bead pointing toward the water pump, place it so it is dry and bolt it in tight to 23 Nm (17 ft. lbs.) torque as you turn the shaft by hand to check that it turns easily. After installing the radiator and heater hoses on the water pump, install and bolt the power steering pump and bracket, place the water pump pulley on the hub and fit the shroud and fan together, making sure the nuts have 27 Nm (20 ft. lbs.) torque. Tighten both upper shroud nuts to 4 Nm (31 inch lbs.), attach the electric fan connector if your engine has one and direct the accessory drive belt correctly to the pump. After tensioning the belt, set the accessory drive back in place, put the upper radiator hose into its mount, refill the cooling system by checking for leaks, link the battery negative cable to the ground and finally start the engine to watch for any further leaks.

  Q: How to Maintain and Fix a Water Pump on Jeep Cherokee?

  A:

  For water pump maintenance, first cut off the negative Battery Cable and empty the cooling fluid. Remove the electric cooling fan from its harness and take out the electric cooling fan/shroud assembly if installed. Take out the two viscous fan shroud bolts and open the four water pump pulley bearings with the four nuts on the viscous fan. You should remove the accessory Drive Belt before you begin taking off the pump fan or fan pulley, if it's attached there. Be sure to pull out the accessory drive belt and then remove both nuts that connect the four viscous fan to idler pulley to extract the fan and shroud. And remember not to store the driver horizontally to protect it from dirt. Remove the pulley bolts underneath the water pump pulley and remove the pulley. Then, remove the Power Steering Pump and bracket. Unhook the lower hose, heater hose and water pump from the hoses and undo the four bolts holding the pump. After that, discard the old gasket. When installing a new pump, first take out the heater hose fitting and jot down its place. Take care to clean the gasket mating surface well so you do not damage anything. Examine the water pump system to find any cracks, leaking spots or problems with the bearings. For any pump replacement, make sure to secure the heater hose fitting using Mopar Thread Sealant With Teflon and follow the package's directions. If you are using the previous pump, take time to wipe the gasket mating zone and see if there is anything worn or broken on the gasket. With the water pump facing the silicone bead, fit the gasket on and tighten its bolts to 23 Nm (17 ft. lbs.) in a clockwise direction after turning the shaft by hand to see if it spins without problem. Bind the heater and Radiator hoses to the water pump, attach the water pump pulley to the water pump hub and screw all the bolts that hold the pulley with a torque of 27 Nm (20 ft. lbs.). After reinstalling the power steering pump, set the viscous fan and its shroud in place and tighten the four nuts joining them to 27 Nm (20 ft. lbs.). Guide the accessory drive belt through the right position so the water pump does not overheat from being rotated closing the wrong way and use the Belt Routing Label nearby if uncertain. Tighten the viscous fan shroud bolts to 3 Nm (31 inch lbs.), fit the accessory drive belt and insert and tension the electric cooling fan/shroud assembly. Tighten the electric fan shroud bolts to 3 Nm (31 inch lbs.) then attach the fan connector. Refill the coolant in the system, look closely for any leaks, set up the battery negative cable once more and start the engine so it heats up while you monitor for leaks.
