I am not sure what my problem is. for awhile now my jeep has been running loud. It sounds like it is running higher rpm than it really is. Recently during a hard rain and flood I drove through some high water, 2.5 feet high. soon my jeep went quiet and I thought it stalled. Turns out it was running the way it did before it started running loud. I guess water plugged up something on my jeep.

Unfortunately this only happened till I left the water. once it went back to running loud the fan belts made lots of noise. This makes me think some kind of emmisions thing is messed up. causing the fan belts to run faster. I don't know whats wrong I am at a complete loss. Maybe someone can put me on the right track.

Thanks

Don't worry, my Jeep sounds like a tank without a muffler.

Still runs doesn't it? and you can still hear the tunes? let the guy next to you at the traffic lights deal with it.

Do you think insurance will cover the carb if it some how "teleports" behind the tires of a 350 with dualies?

The problem is when it runs quiet I gain 30 horsepower. I am much slower the way it runs now.

Do you have a fan clutch? It sounds like a fan clutch that's always engaged. The loud roar you hear is from the fan and the water probably cooled the clutch enough to disengage it. Once it dried out, it re-engaged. Just a guess but it's somewhere to start looking.

would my fan clutch always be hot and run loud even when I start my Jeep?

I I have a couple of holes in my exhaust, about the size of 2-3 mm. The thing that really made me wonder what the problem was is when It switched from quiet and more hoarsepower to loud and less hp my fan belts squelled like they were changing speed but my engine rpm stayed the same.

No your fan clutch shouldn't be loud and engaged when you first start your Jeep. That's what I'm trying to say. You need to check it out and see if it's working properly. Sounds like it's not. Before you start it in the morning pop the hood and see if the fan will spin easily. If not you need a new fan clutch.

I went to a goodyear auto repair shop and he said my fan clutch was bad. Now I get home and see you response snowtow.
My fan won't turn easy. Also just today while driving home it sounded fine. Just that one of the bearings on the fan broke. As I was driving home I would notice little sounds like gravel hitting my undercariage. It was the small ball bearings.

Now I am either thinking of an electric fan. But I think if I can't find one at a junk yard I will install a new fan clutch. It doesn't look that hard, just four bolts and the fan pops off? I will look at it tommorow morning. Hopefully I can take my jeep to lefthand canyon this weekend.

Stick with replacing the fan clutch. It will work much better than an electric fan and you're right, it's very easy. Loosen the belt (or belts) and pull four bolts.
