Jeep Cherokee 2.5td overheating

It's probably air locked. This isn't uncommon when you do work on the cooling system. Simply leave the rad cap loose for a couple days while you drive. Keep the heater turned on as well. Check the rad for coolant level and keep it topped up and your temperature should settle down. Then tighten the rad cap. Hope this helps.

do you have a hose that is collasping on you, please check them.

not servicing when oil is due or using the wrong oil or sometimes water gets into the oil and turns it that greyish colour

How to diagnose an overheating 3.7
It might be the timing belt!

Check if water in oil, take of oil filler cap and check the oil colour, if brown milky colour, head gasket blown, could be a faulty thermostat. Thirdly, faulty water pump.

perform a pressure test on the cooling system,it will tell you if you have a engine overheating problem.
also look at your oil and see if you have water in your oil,test your exhaust pipe for signs of antifreez coming out of the engine.

i change the radator get a new one it fit the problem

If a car dies from overheating its not good. Quick check; pull the oil stick and see if the oil seems milky. Mess with it enough it will start. More than likely it has a blowed head gasket. You will see water out the exhaust while running. Good luck

First, start engine and attempt to re-fill with the heater on hot. Sometimes they can get airbound. There is little chance this is being caused by the water pump. Far better chance that the radiator is internally plugged. Jeep radiators are notoriously small for the application and have little room for "error" Partial flow will cause this problem... I've seen it as the major reason aside from a head gasket failure for overheating (assuming you put the stat in correctly) I use a swimming pool pumpfilled with household "lime away" rust & lime remover (which is usually what obstructs core tubes). to backflush these, but you may wish to have a shop do it in a more "normal" way.To do this correctly, the radiator must be removed or rust will remain in tank.

the reason it getting hot when stopped is the fan relay is out thus not turning the cooling fan on,this is a time consuming job,the relay is located on the passenger side tip of the frame behind the headlight,the grill,headlights,bumper,and tip of the front fender has to be loosened up to get to it.
The relay is about 70.00 or so,the engine cools down when you drive as you are forcing air through the radiator to cool it down,as for the heater issue probably caused by boiling the anti freeze out ,
To make sure the engine is ok do a compression check to verify the headgasket and heads are ok,as for smelling the sweet smell which is antifreeze probably due to overheating and pushing the fluid out of the cap or tank.
