So can regular off roading affect this?

I don't have my manual in front of me to see the wording, but other people in this thread have said that 30" is the max water depth for our Jeeps. So it must have been the Jeep website that I read the other half of that - they say 30" at less than 5 mph, or 10" at greater than 5 mph. Presumably that would be due to the increased risk of water splashing into the air box at higher speeds.

If you look at AEV's faq on their snorkel they say something to the effect that while a snorkel does help eliminate the risk of water in the air box, there are still plenty of other things that can be affected by fording deep water so they still never recommend going deeper than what the owner's manual says.

Putting the two ideas together, I gather that means it's still never a good idea to go deeper than 30" without a lift but you could theoretically be a bit less cautious about your speed if you have a snorkel. Still, high speeds are probably a bad idea regardless.

But assuming one has addressed the breathers and air box issues, what else is there to worry about? Wiring, either under the hood or in the doors/seats? Anything else?

I was told not to go through water that is higher than the top of your rim. Regardless of what vehicle you are in. Keep your speed steady but don't go to fast. Keep a bow wave in front of the vehicle. The only other thing that has not been mentioned is to get out of your vehicle and walk through the water first. ( not always practicable, but if you can, do it ) Then you can find the washed out parts of the road which you need to avoid. Your jeep will die or float away just like any other vehicle. It may make you cold and wet, but at least you have a better chance of getting home.

The main point is to use common sense. Be sure of what you are doing. And when you get home, check your oils for water contamination. Cheap to drain and replace.

OK, I checked. The rear hose is 29" above the ground. The front one was in the left fender and was 34" above ground. I guess then if I kept it below that for now I will be good. I will def be modding that higher at a later date.

Shenanigans. Your dealership better be ready to absorb the hydro lock claims if they keep telling people that.

Manual states 30".

Trail Rated badge is about 40".

Simple concept. Simple solution. If you Gunna go swimming with your jeep. Design it to do so. Or your Gunna sink. If you think because your breathers or air intake or what ever is at x". So If the water is 2 inches shallower your safe. Well. Good luck with the rebuild. After you rescue your rig.

Build and prepare for worst case scenario, and you might just make it. You save yourself, and the people who would have to save your ass, alot of time, effort, and resources. If you plan ahead. Prepare. And use common sense.. At the end of the day, you'll be ok. Bottom line. Just don't be a retard. Lol

I thought the 2012 and earlier models had a 20" max water depth and the 2013 had a 30" max as the alternator was moved to the top of the engine compartment. Yes? No?

I think the '11 (3.8L) is what you're referring to with the alternator location. My 2012 (3.6L) has the alternator up high

Just did my very first mod Big thanks to Rooster76. I read his differential extention thread and just got done with mine. I have only done the rear at this time. The clearance went from 29" to 45". Cost me 15 dollars. Sweet!!!!

Doing the front next.

Stay out of mud unless you have to, stay out of water unless you have to. If you can't tell how deep it is don't go in. Common sense. If you want to play in water buy a boat. Nothing wrong with having a snorkel and breathers "incase shit happens" but Jeep builds a great 4x4 and a poor submarine. Most trails everyone knows the water crossings and time of year, if your in BFE by yourself or with friends in BFE think twice.

We actually have a law in Arizona called the stupid motorist law for idiots that drive through flooded areas and have to get rescued. A flood here during monsoon season can actually take your car downstream with only 6 inches of water. Its not worth it.

If a stupid motorist gets rescued they are charged for the rescue. Happens every year and people still die. Just boggles my mind.

Finished the front. I ran it up the drivers side and ended it next to what I believe is the ABS unit in front of the master cylinder. Cost an extra $7 dollars. So far in about $22. I am going to think about doing the transfer case. It is already 40" above ground. i feel more comfortable if i need to go through water.

Gotta say it was easier than expected and happy I did it myself...

Just remeasured. The transfer case breather is 37" high. Thats the lowest point now unless I missed something. 8" for $22 and about an hour a fiddlin around not bad.

Yep - go out a get a hose mender and extend those breathers. The front isn't much better, it's on the driver's side, just behind the top of the shock mount.

There may be a difference in placement, but not max depth. My 2009 manual states 30" max fording depth.

That measures about to the Wrangler decal on the fenders.
