SOURCE: Coolant filling up overflow bottle

You may need to ask AAA to put a radiator pressure tester on the resevoir bottle and pump it up to operating pressure(Pressure cap rating) and see if it over pressurises while it is running at operating temp,rev engine up and down and watch what the testers pressure readings do,it should move up and down in sync with the water pump.If the pressure keeps building i would have to believe that combustion chamber gases are over pressurising your cooling system.Also test the pressure cap is functioning within factory specs.

SOURCE: 2001 Jeep Grand Cherokee 6 Losing Coolant

Pull your oil cap, check on the underside, if its white and thick you need a head gasket. that would explaine why the dealer telling you that you need a new headgasket. if it "looks normal" change your water pump.

First, DO NOT DRIVE YOUR VEHICLE OR RUN THE ENGINE AS LONG AS YOU HAVE THIS CONDITION!!! (exception:can be run 1-2 minutes... for short intervals while testing only). If you run/drive, you can cause severe damage to engine bearings.
1. If residue in radiator appears as semi-thick (like milk shake) light coffee colour, It indicates engine oil in cooling system. Major cause is a blown head gasket or cracked cylinder head. This condition usually is accompanied by an overly high oil level on dipstick and wet residue on inside of oil fill cap that is similar to what was found in radiator.
Testing includes pressure test of cooling system. Other symptoms are white smoke from exhaust pipe or coolant on one or more spark plugs (depending on severity or location of failure).
2. If residue is reddish in colour, it indicates a failure of transmission cooler coil within radiator. There is no safe test for this other than identification of contaminant and radiator replacement, including complete trans flush. This condition is far less common than head gasket problems.
3. There are two other coolant entry points to consider depending upon which engine you have: Coolant on any V8 or V6 engine can enter crankcase through intake manifold seals. Some engines use an intermediate housing between the water pump and engine which have passageways for coolant. Gasket failure can allow coolant entry into the engine at this point. (This is also rare but can happen if any bracket bolt that passes through the water pump and intermediate housing has been left loose during or after an alternator, or other accessory repair)
4. If no leak is found, if you just bought vehicle, find out if headgasket has just been changed It is possible that either residue from previous failure was not flushed from system, some type of block sealer was put into cooling system or if gasket was changed, perhaps condition was not corrected and still exists.(ie: gasket replaced but head was cracked or warped and not replaced).
In any case, this should not be ignored or dismissed!!!
Good luck!!!

SOURCE: Vehicle needs to purge all the air form the radiator. Jeep Grand

Run engine normally while filling radiator. Leave heater on high heat. When engine temp reads normal, shut it off, wait about three and complete filling.

2006 jeep grand Cherokee limited if the radiator overflow jug is empty will it cause the transmission temp light to come on

I would say it is possible an overheated engine which is not coolling the transmission can trigger a lot of lights. Many transmissons are heated and coolled by a line which goes to the radiator of the engine cooling system.

My 2006 jeep grand cherokee is leaking coolant and started to overheat it is leaking on the passenger side in the front outside of the car My coolant light is not on and my heat is not working

Sounds like the hose running to the radiator is cracked. You will need to replace it ASAP. As over heating can damage your engine and engine seals such as piston rings. Hopefully it is a hose, or it may be the actual Radiator, if it is the radiator you will be looking at a look more $$ to replace that. Some rust after a while, especially on 4WDS when you take them off road and into salty waters such as rivers, ocean beaches etc etc and never rinse it off with the hose after the 4WD is completed, salty water will rust out radiators and anything really like shocks too.

3 months ago i changed to a new radiator after going trough water bottle after water bottle.Things were fine.Now im over heating again with the problem being the pressure cap of the water bottle apparently...

There is no water bottle

All vehicles have a coolant recovery container

When the vehicle warms up ,some coolant goes
past the radiator cap into it

At night when cool, the radiator draws back what
it needs

Been that way for 50 years

That container isn't under pressure as you can see

You have to diagnose the engine overheating issue

You have a new radiator,I would assume new thermostat
& rad cap,so continue on

It is very old, so a head gasket wouldn't be a supprise

Changed radiator hoses and cap. changed coolant. still not getting flow with overflow into bottle. Thinking it may be bad thermostat. had coolant come out under cap. checked bottle and cap and no leak...

I had a leak on my top on hose on my jeep it was such a small hole I couldnt even recognize it. Almost mistaked it for the metal pipe corroding through. Now anytime your messing with the hoses it is best to just change the thermostat. They are cheap and easy. I would try that and go from there. Also how hot is it getting? 220 degrees is normal for jeeps. Should go a little past the middle line. Then the fans kick in and bring it back down. Also squeeze the hoses once it gets all the way hot and see that they have full pressure in them.

Engine smells like rubber burning and temperature gauge at normal temperature. Water/coolant leaking out of reservoir and needs to be filled ever 2 days. Oil level is normal, but when it's hot outside the...

Generally that smell is caused by an oil leak that is getting on either the exhaust pipe or manifold (doesn't take much to smell). As far as bottle getting low, I've got a 93 that never stays full but only needs coolant in the radiator about once every two months. Been like that for two or three years and has never overheated. I'm sure there is a small leak somewhere, but I'm not driving myself crazy looking for it. Check all hose connections, and look on the ground after being parked overnight...If it's leaking, something will show up. But if the radiator is staying full, just check it when checking oil level.

2000 grand cherokee i can hear water gushing from the heater core, i had to always top up my coolant in the rad. coolant reservor does not go low at all but, loosing coolant from the rad.

Replace the radiator cap. If it is working properly it will pull coolant from the bottle, if it isn't pulling coolant then it isn't holding pressure and leaking. The gushing water sound is a sign of low coolant.

1999 Gr Jeep Cherokee-antifreeze issue

how often does the warning comes on doing the week or in two weeks? if it was a one time thing or this takes place every 3-5 months i wouldn't worry about it. i will make sure that the radiator cap is on tight. you said that all hose seem to be in good condition i would check the radiator where the cooling fan covers the fins and the water pump because it has a warn hole at the base that will seep out antifreeze when the inside seals are going bad these will cause the smell also.

1989 cherokee xj major overheating issue

Fill up the cooling system and start the jeep. Let the jeep get at operating temp with the radiator cap off. If the coolant level goes down, add more. Keep your eye on the radiator level and see if any bubbles appear while the car is running. DON'T keep your head over the filler neck, if you do see alot of bubbles or air bubbles, you could have a bad headgasket.

Your cooling system is air locked it need need to bleed it. The easiest way is by a 5/8" heater hose T and install it on one of the heater hoses. It make bleeding really simple.
