1999 Other Jeep Models Need help to replace the water pump

Ok luck has it for you that I own one and have replaced it. So first on the right side (passanger side) there is a drain for the radiator on the bottom start with draining it. Now you have to remove the fan shroud and then you need to get a fan clutch tool to remove the radiator fan and clutch (call to your local parts store to see if any of them rent it. Now you need to remove the lower radiator hose and there is a heater hose connected to it. Take of the fan and fan clutch then remove the serpentine belt (buy a new belt while you are there unless it is fairly new already). I also found it easier to remove the upper hose and the thermostat housing so replace the thermostat while you are there. Now you will need to remove the bolts that hold the water pump on and remove the pump. Clean the surface on the engine and put some sealent on it and on the water pump put the gasket on the pump and go in reverse order. I did not remove the radiator when I did mine but it make a lot more room if you do. Hope this helps if you get a repair manual it will show you pictures too I like haynes manuals and some like chiltons you might want to check with your local library so see if they have one you can check out. Hope this helps if you need anything more just ask. Thanks and Merry Christmas.

Oh yea you have a 4cylinder there is no engine fan other then electric so dismiss the fan removal. Now on the lower hose I usually disconnect it from the water pump only unless I am going to replace it. As for getting them loose I us a screw driver to break the seal (putting it between the hose and the pump) and twist and pull at the same time. The other two hoses if they are not in the way of getting the pump out then I would leave them alone. Hope this helps anything more just ask.

Ok there is a 2.5 ltr 4cyl option (in the standard cherokee) which you stated in your original question it says 99 jeep 4 cyl, now on the grand cherokee it was either a 4.0 ltr 6 cyl or a 4.7 ltr V8. Now a 4.0 ltr is a 6cyl. I have a 99 4.0 ltr 6cyl and yes it does have a engine fan as well as an electric for the a/c. So if you do not have an engine fan on the engine then just minus that part the rest is the same. Now answwer this is it a 4.0 ltr or the 4.7 V-8? So if there are any more question ask.

Only if you plan on removing the radiator, other wise no need to. Thanks and have a Happy New Year.
