The cooling system in my 2001 Jeep Cherokee 4.0 6cyl. is expelling a red clay like substance. I purchased this vehicle 2 months ago and flushed it with super flush because of this condition and it's doing it again. Help

    Can you explain a full reverse flush? I have a flush connection in the heater line that adapts a garden house. Is this sufficient?

    I have a Garden hose connection installed in the heater line. Is this sufficent to do the reverse flush?

  • Eric Vanderberry May 02, 2010

    I have a garden hose attachment that is made for flushing the cooling system, through the heater hose. Is it sufficient enough for the reverse flush you referred to?

Are you using dex cool orange coolant?? If so your condition is normal as the dexcool will get clay like when exposed to air. The problem is I dont believe your Jeep is designed to run on Dexcool (for aluminum heads) and it will possibly cause clogs and blockages. Check your radiator/fill cap and double check as I'm pretty sure your cherokee uses standard green 50/50 coolant. If it doesnt say Dex cool on the cap then flush the system and put the required green coolant back in and your problem should go away!

Have a full, REVERSE flush done on it and then add an antifreeze with a rust inhibitor in it. You should add enough to set the freezing point to 10° BELOW zero. This is also an anti boil solution.

    If you have the kit I'm thinking of, it is the right thing. The water will flush out and overflow out of the radiator filler hole.

It could be the fan clutch not engaging which will not pull air through the radiator, it may still appear to be spinning but it could not be at the correct RPM for adequate cooling. Hope that helps.

My 2002 jeep tranmission over temp comes on and off while on my way from work just had a oil change about 1 month ago and had tranmission flush in september what dose this mean

Having once owned a trans repair shop,
I would prefer you not flush the system

Due to the vehicles age ,and not knowing
if the fluid was changed every 30,000 miles

My Past Professional Opinion tells me your
trans is most likely slipping. ,thus over heating

You could check the fluid level but that won't do

Your most likely are close to a rebuild situation

Figure about $1700.00

What type of antifreeze is best for my 2001 Jeep Grand Cherokee? (I just bought it few months ago.) Thanks, Edward

Edward. the recommended antifreeze is the MOPAR antifreeze. I think the additives are the reason that you want that antifreeze.

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

Aircon not working 2001 Jeep Cherokee Sport

There is a pressure valve that keeps the compressor from turning on if it has a low freon charge. Get a self recharge kit that comes with a gauge with colored charge indicator. Hook it up and see where your charge is. It is very inexpensive compared to a pro A/C shop.

Jeep cherokee radiator replacement

single core, 2 core, and 3 core radiators will all cool your vehicle, but something to consider before going to a larger radiator, is whether it will provide too much cooling capacity. This could be problematic during the winter months depending on where you live. Automotive cooling systems are carefully balanced to provide good cooling during the hottest months of the year, but also keep enough heat in the system to warm your passenger cabin during winter months.

2 and 3 core radiators often are used on higher performance motors, that may be creating more heat, and therefore require more cooling capacity.

If you are indeed needing to replace your radiator, I encourage you to use one that is sized similarly to the factory unit, unless you live in an extremely hot climate. You may want to consider using a product like RedLine Water Wetter in your coolant mix with the factory radiator. You may be able to find this product in your local autoparts store. It is a surfactant, that improves the cooling systems ability to shed heat, often by as much as 30 degrees, if I recall correctly.

Had this problem and one thing that even Chilton manuals only show in fine print sorta say is that Jeep cherokee has a relay sensor for the coolant fan usualy right behind the passenger or driver side headlight you may have to remove the bumper also its rather easy.Its a liitle black box thats screwd down on the panel just unscrew it unplug it replace mine ran me around $60.00.Before I learned about this after replacing the thermostate and just about to rip out the water pump my buddy told me about the sensor after replacing over a year ago no problems.
