Question about 2001 Jeep Cherokee

Jeep cherokee 2001 box shape

Water keeps coming out top of block. Mechanic says it is a welch plug which costs almost nothing, but the head will need to come off(which will cost a fortune). Can I do this myself and if so where can I find some info on how to do it.I have tried radiator seal which helped for a few days, but then blew again.

    I read somewhere on the internet about a guy on a trip in africa. He sealed his welsh plug from the outside with Pratley's steel putty.It held for years. I am going to attempt it.(As the finances to remove the head or block are not currently available)  What do you think ?


  • vaughan247 Jan 03, 2009

    Thank-you all for your help.




    It seems very risky, will get a quote to do all the plugs. Jeep say at 120 000km the timing chain should be done. Is this necessary as if I need to pull the engine I might as well do other necessaries ?

    you can try to patch it but remeber it may cost you more in the long run if you cook the motor



    ok this is the way i would do a temp fix on it get a tube of stikaflex ,a thin metal plate big enough to cover the plug and some of the head and a spray can of carby cleaner



    now drain water clean back of head and plug with carby must be perfectly clean apply sealant to plug fill the hole riright up and then apply to plate and fix it to the rear of the head to cover the old plug



    leave at least 24 hours to cure but remeber check water daily and watch temp gauge good luck

Check your coolant to see how low a temp it's good for. What u are describing is the failure of a freeze out plug. They are there to protect your block and head from cracking in cold weather, if you don't have sufficient anit-freeze protection (old anti-freeze, or not enough anti-freeze). If the water in the engine freezes, the freeze out plugs are designed to be a weak point, popping out to relieve the pressure of the freezing water, hopefully saving the head and block from cracking. The other reason for failure is corrosion due to, again, insufficient or old anti-freeze. To remove, u just need an old screwdriver and hammer, knock a hole in the plug w/ the screwdriver, pry it out. Clean up opening, install new one w/ block of wood and hammer. Of course, the location of the freeze out plug is what determines how much room u have to do this, so u have to decide if it's easier to pull the engine, or remove the head. It would be wise to pull the engine, and change all the plugs as angelo63 suggest, when done flush the system, adding a 50/50 mix of anti-freeze/water.

    Hey, it's worth a shot to try to stop the leak. A friend of mine had a radiator leak, and he plugged it up w/ his sons chewing gum, finished driving 500 miles home w/out any trouble, so go for what will hopefully work for u too. Good Luck!

    I had an 88 Cherokee 4.0L I-6, ran it to 260k + miles, never changed the timing chain, (still ran well) but they didn't recommend changing it at that time that I remember, of course, they probably are somewhat different as yours is 13 years newer. If they recommend it be changed, yes I would go ahead and do it. I miss my Cherokee, it was a great vehicle, lot of fun to drive.

If it's the 4.8 it's probably a head problem. The alluiminan the heads are made out of is like a powder that's molded together. Depending on how hot it has run it's probably ruined it. Sorry for the bad news

96 Firebird, Replaced water pump, fuel pump - Now blows head gasket.


Get yourself another mechanic. This guy is not doing his job. It shouldn't cost $1600 to change a water pump and fuel pump. No proper mechanic would remove a thermostat to replace the O-ring and put the old thermstat back in. It wouldn't be uncommon for the coolant level to drop after changing the thermostat. It probably only needs to be topped up. No, the motor doesn't have to come out to replace the head gasket and I don't see it costing $2500. Before you spend any more money there, take the car somewhere else and get another opinion. I bet that if you fill up the coolant bottle for 2 0r 3 days it will stop losing coolant. Hope this helps.

1999 jeep grand cherokee leaking antifreeze


Could be any of above but would start with exaust, if crack in the head gasket on the port side they will be moisture coming out the exaust pipe, First thing u do if find where the water is coming out if no puddles are found it's more likely the head itself. good luck. Personaly i would take that shop to small claims court.

White stuff under oil filler lid


Head gasket between engine block and valve header is leaking coolant into engine oil crank case. Expect a major costly repair because mechanic has to remove many parts to replace head gasket. If you have not overheat the engine, it may cost less. Because overheat engine will damage other components such as radiator,water pump, main seal, oil seal, timing belt.

Blow head gasket


Hi, the head gasket is located between the engine block and the head, which is the part that covers the pistons and usually holds the spark plugs. depending on where the gasket blew you will be leaking oil and or radiator fluid out of or into the engine. repair cost would depend on make, model, and mechanic doing the work. the gasket itself will be the cheapest part of the total repair.
The gasket itself is cheap , the expensive part is the labor.

For a mechanic to replace it will cost at least $500 because there is a lot of work involved and a lot of other parts and gaskets are removed to get the cylinder off. It is made of various materials and depending on what materials it is made out of determines the cost.

Where do I find the freeze plugs on 1998 jeep cherokee sport


On most any engine there usually located under the heads in the block.There should be 2 to 3 plugs on each side.To get to them you might have to remove some accessories such as the manifolds.The plugs should be about 1 7/16 in diameter and made of galvanized steel shaped like a cup.Be sure to look behind any accessory mounted to the block.

The coolant has turned into a thick grayish fluid. was advised that it might be a blown head gasket. how is this going to be fixed and what is a ballpark figure for the cost to fix it.


Well, yes, it does sound like it might be a blown head gasket.

If, in fact that is the problem, the head(s) will have to be removed from the engine and the gasket mating surfaces cleaned prior to re-assembly.

At this point it would be incumbent on a good mechanic to make sure there isn't any warpage in the head or unevenness on the block deck surface that would prevent getting a good sealing with the new gasket(s).

As to the cost, shop rates vary widely, so your best bet is talk with friends, neighbors, relatives for a consensus on a reputable local mechanic.

If you have a Pep Boys in your area, they will be happy to provide a estimate based on what the issue appears to be, which will give insight into parts and labor costs.
