Question about 2001 Jeep Cherokee

1 Answer

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

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.

I have a 1996 jeep cherokee 2wd 4.0L and it is leaking coolant quiet heavily from between where engine and trans meet. Top of the trans is dry. Coolant is coming from inside bell housing between engine and...

Yes, in back of your engine block, there two freeze plugs, these plugs hold water or coolant in the block, to replace these freeze plugs, transmission will have to be remove, if your going to get this done, I would also have the rear main seal replace at the same time, should not cost you much labor to do this, due to if it starts to leak oil from there in the future, transmission will have to come out again, this will save you money and time down the road, hope this was very helpful.

I have a 1993 jeep grand Cherokee. It overheated and wen I put water in it, it flushes straight out real fast near the transmission. Wen I looked at it, it looks like the engine block is cracked. How can I...

Cracked block? Eh... You can try to have it welded but thats not a promising fix. I think you may have signed your jeeps death certificate. On the bright side you can pick up a used motor from a salvage for around $450. Try welding it. Its worked for me before.

The car overheated today, and the mechanic said he found a large amount of mud in the radiator and hoses. What would cause this? Thanks!

That "mud" is actually rust. Back in the early eighties the EPA began mandating more and more MPG. Quickest and easiest way to begin doing that is to cut down on the vehicle weight. Engine block and cylinder head castings were made thinner and the use of nickel (which is heavier than steel or iron) in the alloy they are cast from was cut back. Nickel acts as a rust inhibitor and also helps as a "binding agent",
(without that nickel in there, blocks rust easily, reacting to the acid buildup as antifreeze deteriorates. Blocks and heads are also more prone to cracking as the nickel is very important, helping hold the iron together on a molecular level.
Flush the block really well, have the radiator flushed separately or it will plug up worse. I have seen some engines that were so badly rusted that the welch plugs needed to be removed to let the rust out. Or, replace it altogether.
Best thing you can do is change the antifreeze and do a simple water flush at least every two years.
If you don't you will be right back in the shop doing this same repair again!
OK, class dismissed!
Good luck!!

If you have water in the oil and the head gasket is ok, that leaves a cracked block or a warped head.

On my 2001 Jeep Cherokee Sport there is water leaking from the top of the engine next to the fire wall. Leak is below valve cover. Is this a Cracked maifoil?

there is a freeze plug back of the head that could be it.or leaking head gasket or the studs or bolts that hold the manifolds on may go into coolant passage. just remove stud or bolt and applie sealant to the threads and reinstall

On the top of the bellhousing. From the drivers point of view it is in the 11:00 o'clock position. The harness wraps around the back of the bellhousing and plugs in on the passenger side of the block near the oil sending unit.
