I usually will flush a cooling system when I change radiator fluid every 3-4 years. There are many ways to do this, I frequently will just open the draincock on bottom of radiator, run engine, and allow to drain out with a hose in the radiator to replace. This works better if you pull the thermostat, and it's always nice if you actually drop a hose from bottom of radiator to drain.

Oh, and while running engine and flushing, make sure heater is on full hot to flush the heater core.

Coolant leaking out of reservoir and radiator. I have to fill tank once a week. The radiator seems to be full when checked cold.


replace the faulty reservoir or radiator
what is happening is that the radiator cap is not raising the pressure in the cooling system because of a leak in the system
the excess water from heating is being pushed out probably onto the ground through the leak
when the cooling system cools down , water is being drawn back into the radiator
probably find a crack in the radiator tank that opens under pressure but seal off as the pressure is lost

HOW TO LET THE AIR OUT THE COOLING SYSTEM ON A 2002 JEEP GRAND CHEROKEE


You should have a vacuum puller, but alternatively, you can purge it by letting in freon on the low side and opening the high side for about 4 seconds, that should purge all the air in the system.

It could be the water pump, the air switches from hot to cold because the heater core is the highest point in the cooling system so as you run low on water you lose heat, if the water pump has siezed you are in danger of losing the serpentine belt, so don't wait to get it fixed.

You have a leak in your air conditioning compressor Your system works on the reheat principle All air passing through the system is cooled and reheated before it enters the cabin this sould be dehumidified air but it passes through the heater core and sence the air is not dehumidified you are getting condansation as the air flows the heater core that is heated by the engine heat and the water is from condencation because of the leak in the ac compressor The unit is a press fit in the center of it and fials unfortinatly a lot with this disgien of compressor

If you put the thermostat in correctly (spring towards the engine) that should be OK. Likely if the water pump wasn't leaking or had a bad bearing, you wasted your $ on that.
If you re-filled it and did not have the heater on high heat, you may have some trapped air in there. But, still overheating says another thing. If you have a blown head gasket, it can pump compression into the cooling system and drive the coolant from the core. It will also overheat. You can have that tested at most any decent shop that will do a hydrocarbon test to find that.I think someone makes a chemical test kit for that but not sure if it's very expensive or not. White smoke from tailpipe will also be an indicator as will be any coolant in the engine oil or coolant on one or more spark plugs. If it turns out that it has a head gasket problem don't stop looking for problems as often a faulty fan or obstructed radiator can cause the initial overheat that caused the gasket to fail.

The heater is my Jeep is not blowing very warm air. It puts out mild heat at best. I have a 2001 Jeep Grand Cherokee Laredo.


I would recommend flushing the cooling system and replacing the thermostat.....easy to do and only about $14 for a new thermostat.If that does not work then you either have a coolant leak somewhere or a bad heater core. I would also pressure test your cooling system before you flush the system to look for leaks in the system

Cooling system


All the parts that you mentioned are the correct parts that you need to check if there's a problem with the cooling system in your jeep. It's just that you missed to check two (2) things:

1. Freon
2. Leak

If there's a leak in the copper tube, your car will run out of freon. If the freon is low, then the jeep will not get cool.

Contact an A/C tech to check if there's a leak, fix it and recharge your jeep with freon.

Have a great day!

My 1996 jeep grad cherokee larado is over heating


You have air trapped in the cooling system. This is a 4.0 right? pull the heater hoses to the rear and let the air out. Run the heater, jack up the front end, rev the eng a few times, this should purge the air
