GIWrangler You need to seal your fusebox one way or the other, its not water tight and you dont want any water in that baby!

WorkingMan Does anyone remember the oil company commercial way back ( B/W TV time). It showed a jeep driving underwater with a scuba driver at the wheel, it looked to be in 20ft or so of water. The ad was supposed to show that the oil company was going to extremes looking for oil. Obviously an older vehicle with no electronics (diesel even better) can drive underwater as long as the engine can get air and keep water out. I thought that was an awesome commercial for Jeeps though.

Jared66 It's actually only half way up behind the engine for the transfer . Dunno about an auto trann breather since I have a Manuel.

NFRs2000NYC I extended my breathers for $10 bucks with solid brass connectors. Front diff to the engine bay, and rear diff to the tail-light. Tranny and tcase are high enough (top of the motor) so I'm not worried about those.

Here is a write up for breathers. http://www.wranglerforum.com/f33/ext...se-185089.html

I don't believe fresh water instantly fries electronics. There was an electrician that said he cleaned electronics in a dishwasher. (it was on a "mud in the alternator" thread") I think it corroding is a bigger issue later. Putting a thick coating of dielectric grease in your harnesses and fuse box is something to consider. It is an insulator that will keep water out and prevent a charge from shorting due to water. I haven't done it myself, but I will do the light harnesses soon with my new bumper install. Saltwater being more conductive is something to be more concerned about than fresh water.

I just put in a wire harness for a trailer hitch and found a new breather. It's behind the driver break light. You unscrew the 2 inside break light screws and wiggle to get to it. I believe it is a fuel line breather. It's rather low. About at the top of the license plate, or just a bit below the top of the fender. I'll try to post a picture later.
That's a good write-up on the breathers.

I actually purchased the River Raider kit.

I did want to comment again though, about the "wave" since we've all kind of glossed over it but mentioned it.

If you have to drive in the water, like in that cool video of the flooded road, other than not going in rushing water, you have to get that wave going and not outrun it or lose it (where possible, sometimes you have to stop).

(My old rule was don't go in water deeper than your front bumper, but I've had to do it before.)

The wave works to your advantage in many ways, although it's not exactly what the OP was talking about. (I don't equate "water crossing when wheeling" with "driving through long streches of water with a bow wave" but I suppose in some cases they are one and the same.)

DFW6ER read up on this....it's a one way valve that lets air in when the purge valve allows vacuum to suck stored fuel vapors to the IM to be burned. This doesn't happen under low speed driving like you'd encounter when submerged so there should be no need to install a breather extension to this valve.

That's probably the evap canister. It contains charcoal...a tube should go from the fuel tank or fuel filler hose to the canister, then a line from the canister to a purge valve (unless the purge valve is integrated into the canister), and then a line to the intake manifold to burn the fuel vapor under high engine load conditions (I'm not sure if it's only under WOT or just when the TB is opened beyond a certain amount)

Yeah, that's my understanding as well. EPA mandates to reduce air pollution from fuel fumes. Any fuel vapor is contained in the evap canister and then burned when the jeeps driving at highway speeds I believe.
Also there'd be the danger of a spark-induced explosion if fuel vapors were freely venting into/around the body of the jeep.

Fuel Breather?

- snorkels are also good for dusty areas, if properly set up for that and they look cool all the damn time (so I want one)

- breather relocation should probably be done on every jeep

- gear oil changes are your friend

As a side note, I don't like the idea of a fan chopping water. If you get a good wave and have a front air dam or skid, ok. I've always wanted to get one of those mid height stinger bumpers and make a tarp the same size as the stinger, complete with gromets for bungie cording it in place. I don't know if it would work any better than eye-balling a wake, but I like to imagine it would work :P

Now here's a video of a JK in water that I happen to like

It's peaceful and all,, like one of them sleepy noise making things or one of them fancy zen fountains.

This X1000.

I ran through a few streams in Colorado last summer and that was cool as they were part of the trail network. But crossing 3' of water just to see if I can make it doesn't make much sense to me. I have a Sea Doo for that.

Yeah, I did that in my '72 Super Beetle driving down a flooded street and I stalled out. I got water in my cylinders. I was lucky I did not bend a rod.

Of course, do this with some heavy duty rubber gloves or a wooden stick attached to the fan lol!

OP-If you have a 3" lift and 35s, then you can ford 35 inches of water (stock fording is 30, plus the 3 inch lift, plus half of the diameter increase from 31 inch stock tires). And you can do that at 5mph. As you get heavy stuff up front, it will probably drop the nose a bit, so you may want to get a leveling kit, which will add about an inch, so there's 36 inches of fording, that's 3 feet of water!

I'm pretty sure that fording rating has a lot more to do with the electronics than the air intake, so you're pretty much screwed after that. Yep a snorkel will help with waves/spray etc, so it's probably worth getting, other than that though, you're going to have to pioneer some shit. There may be someone out there who has waterproofed the shit out of a JK, but I haven't heard of it yet, so maybe you can figure it out and start a business doing it lol!

staticattic Yes, please post pics. All of the vehicles I have seen on YouTube that are windshield deep (or higher) are either professionally built machines for such a task or people that have accidentally driven too deep.

If the OP wants to drive through really deep water, picking up a used H1 might be the way to go
You do know that if you keep moving, even with water that deep you will not get anywhere near that much water inside right?

07-17-2013 07:57 AM
hooper You can intall an off/on switch to your electric fan. Just make sure to turn it on after you cross deep water. Deep water to Jeep is over 30" in a stock JK. You should always check the depth of the water/path you plan on taking. Most people have 30" or taller tires so you can use them as a guage. I hope some of the insurance companies deny claims on people who drive the Jeep in deep (30" at less than 5mph in a JK). They are the reason rates are high.

Rabuck You might run into something like this if not well prepared for water crossings...

Depending on how deep you'll be venturing, I'd personally think about how to keep the electric fan from spinning. (Don't have the answer to that one.)
I am just throwing a random thought out, but unplugging would turn fan off.

And to comment on the boat, I haven't seen to many of them drive themselves to the ramp.
