Question about 2003 Jeep Grand Cherokee
This is s common fault after replacing thermostat, there is a system bleed screw located on radiator which will need bleeding? If you warm engine up"only warm not hot" then locate bleed screw and slacken off, not unscrew all the way? You will hear a hissing noise of the air in you system. Very similar to central heating radiator in a house! Once you have water coming through then tighten up bleed screw/bolt and give engine a bit of a run. Hope this helps

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.

Put front end on jack stands. DO NOT WORK UNDER CAR WITH ONLY JACK HOLDING IT UP! Your life is worth more than a 20 buck pair of jack stands. Disconnect battery, negative (black) lead first, then positive (red) lead. From under car, locate starter motor. Carefully disconnect electrical cables from built-in solenoid and motor. Remove mounting bolts. Pay attention if lengths are different. Put'em back where they came from. Rock starter back and forth to break it loose. Reverse procedure for installing new starter. BTW - don't waste your money on a rebuilt unless you enjoy changing them every 12 to 18 months. Make sure you return the old starter for your core allowance refund.

try the water pump - first - make sure the radiator is really full - take the cap off cold and fill - if it looks full - start and run 8 minutes or so - then fill it up - look at ur fan belt - is it tight - tight is about how much pressure u use to make a firm hand shake with little movement - any movement over about an inch is loose - when the jeep warms up the belt can slip and not even make a noise - - new materials don't always squeal. - then be sure ur water pump is ok - they go slowing - the fins wear down - one more thing is the radiator - u don't say how many miles or what maintenance schedules you have or not so that's it for now
