Question about 2000 Jeep Grand Cherokee
My jeep keeps overheating the overflow will boil sometimes.......also some times the heater does not work..............has a new thermostat and stop leak fixed it for a while we thought.........now its overheating again when i start the car it sorta knocks or shakes then dies.....
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.

The head gasket is the obivious solution. You may want to try putting a water pump on it as if this were your problem it would be a heck of alot cheaper than head work..

I hate to be the barer of bad news but it sounds like you have a blown head gasket or worse. Check the oil, does it look like butter? Water in oil. Forget about trying to drive it, have it towed to a shop.

Overheating with knocking and shaking is a very good chance that you have water/Anti freeze in your oil and that would be a blown heat gasket or cracked head or water jacket.(check oil filler cap and dip stick for creamish white reside . That will also explain the constant over heating. In my opinion you need at least a head job or may need to rebuild or replace motor. Good Luck
