So my wife sunk the XJ in a river!!!! :oops: :brickwall

Ok so on monday me and the wifey went wheeling and we found a river and were driving through it and having fun for a couple of hours. Then I let her drive, and me being a dumb *** decided too let her drive with out me in the car. Well needless to say, she found the one hole in the river too deep for the Jeep. The front end was completly submerged, the entire inside of the jeep up to the windows was full of water, and all lights started coming on randomly. Well we pulled it out, jumped it and finally got it to start. I think it was only running on like 3 maybe 4 cylinders. All the lights slowly started going off and working normally, and the dash lights and gauges all started too work. Well on wed I took finally got under it too work on it. I replaced both the diff oils, the t-case, the engine oil, pulled and cleaned the spark plugs, and flushed the radiator. I havent flushed the trans yet due too not being able too find the right tranny fluid in Japan. So my questions for you guys is what else should do?? It still feels like it running on less than 6 cylinders, Maybe there is water in the gas tank???? Also how important is it too use the mopar tranny fluid???? The airbag and ABS lights stay on???? And I read somewhere that I need a special additive for the rear diff???? Thanks so much guys for the help in advance, I really dont know much about jeeps. Always have had old K5 Blazers and now Japanese cars due too being in Japan!!!!

Fill in your profile.

The aw4 can't take the mopar trans fluid. You need Dex/Merc III or equivalent.

If it is an automatic, then it's a AW4. If you have a manual, then you have a AX-15.

Yep Auto guess I should have listed that. How do I find out what my t case and axles are? Haven't done a search yet but thought I'd just ask real quick

Wikipedia has tonnes of info

How much gas is left in the tank? it is possible that some water may have gotten into the fuel.

If you pour some into your tank, it will be safe to burn off.

Theres over a half a tank. Very possible that water got in there. It sat in the water for about 2 hours. I was thinking about droping the tank and just cleaning it out????

If your transfer case has :
2WD
4PT
4FT
N
4Lo

You have a New Process 242 (NP242 or NV242)

If your transfer case has:
2WD
4HI
N
4LO

You have the New Process 231 (NP231 or NV231)

Axles are most likely Dana 30 (D30) in the front and Dana 35 (D35) in the rear. If you go to Official Jeep Site - 4x4 SUV, Sport Utility Vehicle you can request your build sheet on there. I can't seem to find the exact link right now, probably due to lack of sleep. I know I got mine for ZJ last year from there. A build sheet will tell you exactly what your Jeep came with down to the nitty gritty. Invaluable resource to know what all your Jeep has and what it's called from the factory.

It very unlikely that you got too much water in your gas tank. I completely submerged mine for over an hour and go no water in the gas. Its a pressurized and sealed system. You should change all you fluids and also your cap and rotor, check all your fuses and relays and if possible replace all of them. The moisture will cause them to corrode and not work properly. If you had it under water for very long it could mess stuff up dramatically unless you take the right precautions to fix and address all the potential problems. You got lucky if yours would start right up after ripping it out but you could also have caused some internal engine damage from water getting into the engine. What I did to make sure I got most of the water out was drained the oil 3 times. First O just drained it, 2nd time I filled the oil up and added a few cup fulls of diesel fuel because it will attract oil, then I drained it out and put in a new filter and oil.
It cost me around $650 to get my jeep back running right and that's at a very discounted price because I have the hook up with the parts suppliers for my work. I had to replace a lot of electrical and engine parts also tho.

Best of luck.

Yeah, I'd be running a compression check on all 6 cylinders. If the engine was running when it went under water there's about a 75% chance the engine hydrolocked. In which case you've got a piston (or two or three) that have a nice little hole in them.

Yeah it was running then it shut off. I did an engine flush when I changed the oil so I think it's probably good since the engine flush stuff is basically diesel fuel. I will for sure do a Compression check tomorrow didn't really think about that one. I think the engine did hydro lock, since when it did start up it basically looked like a river coming out of the exhaust. But the thing is that it runs totally fine when you rev it up, it just idles kinda bad. My jeep also has coil pack instead of cap and rotor luckly!!!! So I don't need the tranny fluid from jeep? Just mercon 3?

A Jeep running on 3 cylinders over 2,000-2,500 RPM will sound normal. If it swallowed water and then you started it back up without pulling the spark plugs, there's a 99% chance you need at minimum a rebuild of the engine if not a replacement. Turning the engine over with even a teaspoon of water in the cylinders will do MAJOR damage to the internals.

I don't want to be the bearer of bad news, but I think you're in for some expensive repairs here.

Ha Ha yeah maybe. I've never rebuilt an engine though and I don't speak Japanese so It'd be kinda hard too find a machine shop.
