Go to your local auto parts store and tell them what you need and they can give you a belt so you can bypass your ac pump.

Since you added coolant, now it is time to check the fans. If the fans do come on, than your thermostat needs to be replaced, Should be done every 4 years anyways.

Check the coolant level, sounds like you may be slightly low....Be sure heater is on high when filling the system....Look for any air bleeds...

Check your radiator for external and internal obstructions (leaves, bugs etc on the a/c condenser or leaves between the condenser and radiator, rust or calcium deposits inside the radiator core all cause loss of heat transfer)
Also make sure that the system is full and that the electric fan and the clutch fan are operating properly. (electric fan should come on just above normal operating temp and clutch fan should not be "freewheeling" above temp either)
Note: If you need to have the radiator flushed, do it separately from the engine. especially the inline 6 and 4 engines rust up inside and if the system is flushed with the radiator connected, the debris will pack up inside it and actually can worsen the condition.

SOURCE: Hello my 2003 Jeep Grand Cherokee is running hot

If it's equipped with an electric fan, the fan should be on when the a/c is on. If it has a fluid clutch make sure it locks up when it's hot. If fans are OK likely you have a partially obstructed radiator (internal or external).
If it is only a few degrees hotter, that is normal, providing you have a 50/50 antifreeze mix and that the temp increase is not excessive. It gets hotter because the engine is working harder...a/c compressor draws from 5-10 hp to operate.

2003 jeep grand cherokee heater problem


Jeep Grand Cherokee is notorious for broken blend-air doors. This is the door inside the A/C-heater housing that switches the air from hot to cold. You must remove the dash to repair it.

2003 jeep grand cherokee radiator fan doesn't turn on


Disconnect the fan plug and hot wire it to the battery if the fan dosen't run, replace it. Otherwise, check the relay. The system operates by the temp sender sending a signal to the computer that activates the relay that turns the fan on. Fan should also come on with A/C.
