Did you check rad 4 leaks and make sure all aluminum mesh is intaced beetween cores i had a jeep do same thing or could possibly have air pocket let run with cap off while circulating through block check fluid level add if nessisary also they sell a very good product called water wetter its a synthetic helps fluid flow freer good luck

Watch the gage, if it opens every now and again, and then sometimes sticks, you have an air bubble that gets trapped by the thermostat. what you need to do is run it a little, and finally when it releases, crack the rad. cap. it might take a couple of times, but it worked for me

Overheated. Why won't it start?


I'm not really familiar with JEEP mechanics but if you've replaced your water pump and it's still overheating with full water/coolant level, you should check the thermostat; when it fails, it's a common cause or overheating in all kind of cars

Overheating 98 jeep grand chero kee laredo have


You need to either go buy a new thermostat, (because as always 3 out of 5 are bad off the shelf) so try a different one.
Also you can try bypassing your heater core see if it happens again. if it doesn't it's your heater core...other wise your radiator may be bad too... Try the thermostat first though. Good luck,.

Overheating blowing cold air


Check for proper fluid level, water pump drive belt may be defective or need adjustment, faulty thermostat, radiator cap defective, radiator or core blocked or clogged, dirty grille. Hope that Helps

I have replaced the thermostat and water pump and sensor and rad cap. it os still overheating, why?


90% of the time it is a blocked radiator.If it has not been serviced properly over the years.They block up.Jeep radiators don't have a good record.Other than that,head gaskets do play up.Turn the heater on full and also the interior blower. The loss of engine heat through the heater can also be a good indictator.Hope this helps

2004 jeep grand cherokee overheating. changed water pump, thermostat. no heat from heater. and still overheats


Are you losing coolant. If you are I would check your heater core which is located under the glove compartment.

I replaced the water pump and thermostat in my sons 1998 Jeep. It has a 4.0L and the water pump out let hose back into the radiator sits several inches higher than the radiator. This is causing a air lock....


4.0 engines aren't really prone to air locks. Keep the heater on high while re-filling. If you have an overheating problem and you can't get the radiator to fill fast enough, likely the radiator core is internally blocked. When that happens it seems that the upper hose can't be purged of air. Jeep radiators are in my opinion too small for the engine and if partially blocked, have no "leeway" or forgiveness. They just will not fill correctly.
