yea, I've seen it

It's too bad the JK intake design is pretty wimpy, but they've taken the DUMB design and mellowed it some with the better design of the airbox, but

Evidentally this guy didn't know about the "splash" effect, or didn't care !!

Good lesson for newbies !!

The stock JK could idle thru 3' of water, with just a mess to cleanup, but

SPEED --NOPE

Thanx MS-good show-

You can see in his second splash, water spraying right into the crack on the passenger side of the hood where the air intake is. I've been thinking of fabricating something to put right there to avoid water splashes from getting easily getting in there (at least until I get my snorkel), because I've seen pictures/videos and heard of JK's getting hydrolocked in much shallower water with much less spashing, and even on the road in the rain!

i like the idea of a snorkel, i just personally hate the way they look.
i'd love to fab one that draws air from the cabin behind the dash and is sealed to the firewall

But did you read the jeep haters comment about owning for 7 years and it is like a chinese piece of crap? Uhhh so why did you not get rid if it. Has to replace ball joints after 10000 miles. Maybe user error? People kill me. Some people think it should wear like a tank. Even tanks need maintenance!

I did read the comments. I also read the "Do not buy a 2010 Wrangler" article. Sorry Jalopnik, I just don't care for the new interior. The only reason my 2010 has power windows and locks is because I had to have them with the Automatic and A/C.

Yah, and the one I'm looking at getting looks the dorkiest, but because I wheel in a lot of dusty areas it's probably the best thing for me.

Ummmm - How about Duct Tape - may have to watch the temp gauge though...

it kinda looks like one of those lanterns you see at the end of people's driveways.
they are definitely useful, i just wish they could make them look better.

Still pretty new at most of this stuff, but I don't understand how a snorkel would help.

Wouldn't driving in the rain have the same effect?

I realize it doesn't, I just don't know why.

I understand water crossing if you gotta do it to get where you're going, but finding a mudhole and driving back and forth through it just ain't my thing. The only reason for doing it is to see how much your rig will take before something breaks....looks like that guy found out within the first 30 days of owning his. That was the pass that did him in but he'd been out there for awhile before he broke. Tough break, but if you're gonna play you gotta pay.

I looked at the video. 10 inches of water? Except for the intial rut, it did not look like it was that deep. Speed of approach was the factor here. Sucks though.

it looks to me like he is going some what fast and that's 6sec of a lot of water splashing. just look at the radiator there is a wave of water coming on the top from the engine area inside the hood right before it die( that a lot of water inside the engine compartment ) that to me is more than 13in of water for a split moment at 0:24sec on the video and that were the wave starts to happen at probably 10mph.
For the new guys out there:
If you crossing water GO SLOW really SLOW and you will be fine if the water is below the bumper

agreed on taking it slower. i've never blasted through water like that, never felt the need to either. if for nothing else than to not tear up the creek bed or whatever.

Yah, when I first saw that pre-filter on someone's Jeep, I joked that it's a Jeep-mounted camping lantern fueled by gasoline.

I'd like to try and answer your question, but honestly I'm not clear on what part of the snorkel's implementation you don't understand. Maybe AEV's website can help.

It seems it would be very easy to keep out splashes. Now for crossing 4 feet of water that's different. Is the tj susceptible like this?

Seems like a simple box that would require the water to go through a up down up route would work.

Poor guy....

First time I went off road I went through a rather large water hole and water engulfed the whole front end of my Jeep.....it didn't stutter one bit....and I did it twice.

My Jeep had WAY more water hit the engine than that guy's Jeep

Did I get lucky??

This is actually just a little misleading if you don't watch the video.

The entry into the water was a bit deeper that 10" combine this with the speed that he was traveling actually made the water have the same effect as if it were 4'-5' deep because of the way it was pushing the water.

With the force of the water probably shooting up the air intake to the filter it didn't take long for the filter become saturated. Also it may have actually pushed the top of the air box enough to let a significant amount of water in.

Either way his speed along with the water conditions were the biggest contributing factors. To try and blame this on Chrysler or the Jeep is just not realistic.

Sure a different intake design may help but this was operator error more than anything else.

There is no excuse for a Jeep Wrangler to get Hydrolocked like that. It is piss poor design and Jeep should pony up and replace the engine.

He submerged his bumper 2 times before it died. His front diff alone should be 11 inches from the ground. Drive fast enough you could probably flood the engine in 6 inches of standing water.

What is it about the design of the intake that is so poor? What could jeep do to improve on it (aside from a factory snorkel). Would it be as simple as some kind of "shield" to prevent a splash from reaching the intake?

By the way- I'm not directing this question at anyone specifically...I'm genuinely curious to hear ideas on how it can be improved.

I don't think it's designed, or should be designed to ford a water crossing at that speed. I think common sense would dictate that there could be only a bad outcome. I don't see why anyone would want to cross a water obstacle like that. It's not a landing craft. If I have to go through standing water it's going to be at "crawl" speed. I don't think up to 24" should be unrealistic if done properly.

Anyone ever use a pre-filter over the inlet? I know most pre-filter are only water resistant but it seems like it would help deflect a lot of the water away before it could get into the box. I am only talking about using it when you know you will go through water. Even wonder if there was a way to install a one way valve in the bottom of the box to let water out if it got in.

I did like the video that popped up after this video played



or this one



These make a good case for a snorkel

I agree, but I also agree with some of the comments in the original article. Jeep does state this in the manual, but they sure don't do a good job of illustrating this if you check out the water fording vid on their site:

You're right. The first one is really unrealistic unless you want to increase your chance of hydro locking the engine. The second one is more realistic but I still wouldn't take a water obstacle that fast. What's the point. I think the goal is to make it across not how fast you can do it risking your engine. If they drove it my speed no one would be interested and watch.

My '09 manual says that the Wrangler can ford 30" water crossings at no more than 5 MPH. It also says to use 4L.

Extreme care should be taken crossing any type of water.
Water crossings should be avoided, if possible, and only
be attempted when necessary in a safe, responsible
manner. You should only drive through areas which are
designated and approved. You should tread lightly and
avoid damage to the environment. You should know
your vehicle’s abilities and be able to recover it if
something goes wrong. You should never stop or shut a
vehicle off when crossing deep water unless you ingested
water into the engine air intake. If the engine stalls, do
not attempt to restart it. Determine if it has ingested
water first. The key to any crossing is low and slow. Shift
into 1st gear (manual transmission), or DRIVE (automatic
transmission), with the transfer case in the 4L (Low)
position and proceed very slowly with a constant slow
speed {3 to 5 mph (5 to 8 km/h) maximum} and light
throttle. Keep the vehicle moving; do not try to accelerate
through the crossing. After crossing any water higher
than the bottom of the axle differentials, you should
inspect all of the vehicle fluids for signs of water ingestion.

There isn't anything wrong with the design when those instructions are followed. The issue comes from a combination of things. There has been speculation that the air damn along with the fan, tends to throw water in the direction of the air box.

Quite often in these stories it's not the first pass that does someone in. They always say that they went though 5 or 6 times with no problem and then it died. The engine and the air box can handle some water. The filter soaks some up and there are drain holes. Once that filter is saturated, the engine is sucking air through a wet filter and pulling any moisture into the intake.
