title says it all. how deep of water/mud should one go in with a stock JK before the vehicle gets flooded or messed up!?

 

Hit it at the right angle/speed and this can happen.

After it sat for a second i was able to start it right up... no water in the intake so i'm not sure why it stalled.

Wierd. How deep was that? It is hard to tell because of the splash but I guess it looks like it was up to the bumper at one point. Did you use 4WD the whole time?

 

4wd lo the whole way... 2nd gear.

The deepest part in the line i took was about level with the bottom of the door. If i were to sit in it, it might run into the floor boards.

It's like the engine was starved for air (as if i sucked in a little water) but when we pulled the air box, both the bottom of the box and the filter were bone dry.

Not bad for stock street tires and no lift. A few of the bigger Jeeps got stuck in the same spot.

 

So I guess my question is would the jeep be fine if that creek was longer? For example, if you are driving in water up to your doors for a longer period of time?

I am not a car-mechanic kind of guy so I dont know where the engine starts to suck up water.

 

If you take it slow enough and keep behind the wake you create, you can be as deep as the headlights probably. But that is cutting it close and the smallest wave could send water into your intake.

I only went that fast because 2 in front of me got stuck... and they had some big wheels.

If you want to take a close up look where your intake is, pop the hood and look where the intake sits (front passenger side by the fuse box). If you get the water level up to that hole in it, it will start sucking up water and possibly ruin your engine.

 

Thanks! I will check this out tomorrow. So what about the exhaust pipe? I have heard different opinions about it possibly sucking up water and NOT sucking up water. This question mainly arises when you kill the engine or start the engine in the water. I never know which to believe.

 

Well... someone took a deeper line and got stuck (up to the rear tail light). He was sitting at idle and his exhaust was bubblin away like there was nothing wrong.

Now if he shut the engine off and left it that way for a while i could see that possibly happening. But to stall the engine in deep water and have it fill the entire exhaust system by the time you start it again i have a hard time seeing.

 

Get A Snorkel and you can go all the WAY

I think the owner's manual says fording water to 19" deep on a stock JK. If you figure in an average 2.5" lift and 35's, that increases that to about 23~24". The main concern for water is your air intake (which is located where Seiran described), and any air breather lines connected to the axles. I am not clear on how Jeep calculates the 19" since it is obvious that the air intake is much higher...but suspect it is 19" to keep the inside from getting wet.

Sieran's video's are great. I was there that day and like him, several of the Jeeps stalled out for some reason right at the end. The air boxes were dry, and they started up after a minute.

I was really impressed that Sieran got thru with his stock setup. Many of lifted/modded Jeeps had more trouble than him. Something about his line just got lucky.
