you're biggest worry would be water getting into the cab, and getting into the vents for the diffs. I know for the FDII they are up higher, above 19" to give it the 19" fording, for a FDI, they have not done that, I am not sure where the vents are for the diffs, a crawl under the car would be worth a check, but it also doesn't have the extra sealing around the doors, so I would see which is higher, the doors or the vents, and i would stop before I go to the lower one.

I looked online, and couldn't find anything specific about how deep it can ford.

 

I believe about 16" is the safe range for FDI

 

anyone personally know about how deep we can go?

 

I've been almost to top of my front bumper(middle section) for a 10 foot stretch.

 

your FDI or FDII?

 

I haven't gone through super deep water, but usually the deepest I try to go through is just to where it starts at my doors, which is probably around 14-15" since I've measure nearly 12" of ground clearance. The nice thing about our diffs is that the diffs themselves are tuck up nice and high so if they are submerged as AIC said the breathers are up higher (on FDII) I would imagine the breather's for FDI's wouldn't be super close to the diff themselves, but I can't confirm this.

Forgot to have my camera on for the first leg of this flooded road, it was just to the black rocker panel on my jeep. The video is the 2nd part which wasn't as deep.

You're doing it wrong. You need to go faster to have a proper bow wave which helps prevent water from entering the engine.

 

FDI I crawled into it slow although once I did realize how deep it was I tried to get outta there fast cuz I didn't want to see what that water was gonna get into

 

I have gone through about a foot or more when the roads by me flood with my FDI no problems with seals or anything.

 

nice, i wonder if you can move all the breathers up on the FDI

 

Thats what I was wondering if you did that and some work on the seals you could get deeper.

 

ya if you bring the vents up to the level of the of the intake and do some sealing work you could sink her up to the headlights lol

 

I went through some real deep stuff before. It was over my front bumper since the wave I was creating was over the front hood. The jeep started to float some and I lost traction on the bottom the pond/lake/river but managed to use my momentum to get across. It didn't stall somehow and my transmission hasn't had any problems with the breather or whatever it is called.
I definitely don't recommend doing this.

Personally I don't think there are any differences between the water fording depths of fd1 and fd2 for the manual transmission.

 

Oh i don't doubt I may have been doing it wrong but as I said before this water wasn't very deep. Based on my lift and larger tires what I went though wasn't even close to doing any damage

 

I went in water like that yellow jeep. And my insurance had to pay 6500 for a new motor and heads.

 

I did hydrolock the motor this year (not in that video). My first thought was "YAY HEMI!!!!" But actually after changing the oil and cleaning the mud off the MAF sensor (yes it truly had a chunk of mud on it) it runs better today then it has in a long time. Just needed a bath I guess.

 

I ran through about 1.5-2" of water at about 30mph and managed to get the air filter a little damp..

FDI
Deeper than 16". No issues except maybe little water in horn. No major issues. However, not suggested lol

 

looks similar to something I did
