98 jeep Cherokee keeps over heating

Several possibilities, including blockage in coolant tubes of radiator, damaged or slipping impeller on water pump, blockage of air flow through radiator, inoperative radiator fan(s), damaged head or head gasket...

Does the radiator fan come on? If not, problem could be bad temp sensor or fan motor or wiring.

Why after replacing my radiator due to a crackk, why now dose it overheaqt right away ? replacede thermostat and radiator and bled alot of air out??

possibilites 1, you still have air in system, 2, You put the thermostat in backwards.. 3. new thermostat is not functing properly.. remove it and check in a pot of boiling water.. you should be able to see it open just as the water boils. 4.Does it have electric fans? Are they running ? 5. Possibly a bad water pump. 6. possibilty a loose fan belt possiblty 7. Bad fan clutch if you have one. 8. A very obscure one.. The raditor hose collapses from the water pump suction.. that is why the hoses sometime have a "spring" in them.. Most likely.. Air in system or Thermostat problem..

My 2000 Jeep Grand Cherokee overheats in idle and when the A/C is being used, have replaced thermostat, relay switch, radiator and water pump what could be the problem.

Sounds like your radiator fan is not working.
Have your replaced the fan or fan motor?
Fan motor will cost $100 /diy
Also, check for recall on this fan and motor through Jeep

Just had the radiort and thermostat pulled from my 2002 jeep grand cherokee. after driving for 30 min or so...the water in the coolant resevoir is bubbling hot and the temp hand starts to overheat.

When the radiator and/thermostat is replaced in a Jeep, the system needs to be "burped" of any air let into the system. Park the vehicle on ramps or an incline with the front end pointed up. Remove the radiator cap and run the engine. If there is air in the engine, bubbles will escape from the radiator cap (which is now the highest point). Watch the temp carefully while doing this for overheating. If it still overheats, my best inclination is that the thermostat itself was installed backwards and there is no flow. This is easy to do if not paying close attention, it will fit either way. Could also be a bad thermostat. If the burping doesn't work, install a new thermostat paying close attention to flow direction.

Engine overheats when idling. Top of radiator exploded! Now I must replace radiator. Did bad thermostat cause this, or was the culprit a bad radiator fan relay?

It could be either.Replace the thermostat anyway for good measure (it's cheap).And have the fan and relay tested.I't a very easy quick test that any honest,capable machanic can do

2004 Jeep wrangler 4.0 - 6cyl overheating

I had the same overheating problem in my jeep ! My problem was finaly found out to be the clutch in my fan its a different kind of clutch system it work as this. When your jeep gets warmer the tighter your fan clutch gets .While cool your fan moves slowly. now to test your clutch just warm up your jeep and rev it up a bit if your fan dose not pick up speed then it is sliping.What will come out of this is that you fan will the seez and run full all the time. if you jeep dose not overheat wile moving then it is not your thermo stat period.
