Have a 97 jeep cherokee 6cyl. It started over heating and leaking so the water pump and thermostat were replaced and so it stopped leaking and over heating but there is this little knocking sound that gets louder the longer it runs and also when the wheel gets turned.. Any ideas what it could be?
First I was going to say the valves were damaged from the heat or lack of oil, but that would not make sense if the steering wheel is turned.
The power steering is about the only thing affected by the steering wheel.
I would take a piece of heater hose and use it as a stethoscope to listen around the pulleys for the noise with someone turning the wheel.

Hello Sir,
Here's a step by step proceedure to remove and replace the water pump on your Cherokee.
Be advised,all 4.0L engines, some 2.8L engines and some 4.2L engines have areverse rotating water pump. You can ID these from the word REVERSE orREV imprinted or cast on the housing and/or fan. There will also be an'R' stamped into the impellor.
Make sure your replacement pump is the correct type, If not, expect some major turmoil.
The procedure:
1. Remove negative battery cable
2. Open radiator valve - drain cooling system
3. Remove cooling fan and shroud
4. Remove belts (see my tip on serpentine belts if needed)
5. Remove water pump pulley from hub
6. Remove hoses from water pump
7. Remove accessory brackets from the water pump.
When removing the P/S pump and/or AC compressor, leave the hoses attached and move them out of the way.
8. Remove the remaining bolts and detach the water pump from the engine.The bolts are three different lengths. Make note of where they camefrom.
9. Compare the new and old pumps. Make sure they match.
10. Scrape off the old gasket material.
11. Apply a thin continuous line of RTV High Temp sealant to the water pump side of the gasket.
12. Put a couple bolts through the pump to hold the gasket in place and mount the gasket.
13. Apply Another coat to the other side of the gasket.
14. Attach the pump to the engine. Screw the bolts in finger tight.
15. Attach the remaining bolts.
16. Tighten them up in 1/4 turn increments.
17. Re-attach all the stuff you removed
18. Refill the coolant, adjust belt tension.
19. Run the engine and check for leaks.
Hope this is very helpful

Since your blower is working and it is a heat issue,thats where we'll
start,First thing is have you checked the coolant level in the radiator when
engine is cold,make sure it is filled to top,next verify you have coolant in
reserve ,Start your van and get it up to normal operation temperature,If your
heat gauge on the dash works correctly it should be 190 degrees,Now lift the
hood and locate the two heater hoses going into the heater assembly at the fire
wall,Both hoses should be hot to hold on to,if both are hot and no heat inside
your problem will be the blend air door in heater assembly.
if neither hose
is that hot you need to replace the thermostat in the engine to get it up to 195
degrees.
if one hose is hot and one is luke warm then the heater core is
blocked and to blame. hope this helps you.
Testimonial: "Thanks!!!"

I have 2000 jeep grad cherokee. I have noticed some radiator leak once a while, then was increasing and the light was going on every 3 days or so. So I added STOP LEAK and it did stop, but now the heater is blowing cold air...How can fix this problem? Thank you.
