I took my 2002 disco 2 out on some trails for the first time yesterday. Lots of the trails had water over them. I understand that that the disco 2 cannot cross water higher than 20". From my research a snorkel would not fix the issue of increasing the ability of the truck to cross water. My question is what else would be needed to increase the water crossing ability of the truck.

Thanks

 

Well all I can say is I certainly exceeded 20inches during Hurricane Harvey. I had water over my hood (3inch lift and 275/70R18's on it at the time) 6 times in a row at 3/4 of mile crossing if not more. I had to do what I had to do, but I was still smart about it. I tried my best to go when the water had calmed down, and I kept the bow wave out in front of me (unless an idiot decided it was still a 2 lane highway or a military truck or air boat decided to just disregard me and cause my say 3-4ft bow wave to suddenly turn into 4ft up to the wiper blades for a split second...). I was not running a snorkel, but I knew the intake was in the fender so if you kept a constant steady pace water is actually pulled away and down the side of your vehicle.

I pulled over and immediately inspected my air filter and made sure everything was good before I continued (other people never stopped to check a single thing....) Once I was done I immediately planned on draining the diffs, checking the engine oil, TC, and transmission. When I checked them I found them perfectly fine with zero contamination!!! I also didn't get any water inside my D2 which truly shocked me.

So with all that in mind 20inches is NOTHING to a LR. Just use proper judgement, and upkeep and you'll be fine. When I had 2 05 Jeep Wranglers they'd get water in the axles just after a tiny 1ft deep water crossing. I eventually installed 100.00 axle seals which solved the problem.

 

Where did you get the 20 inches from ? Nothing on your Disco is that low, even the air intake is high on the fender although it might be close stock. 20 inches is about 3/4 they way up my tires and I have been deeper.

 

The users manual says 20"

 

Why would a snorkel not fix this ?

can you copy and paste the statement 20 inches from your source ?

 

How deep do you want to go? Yes 20” is in the literature but my guess is that it’s the “safe” depth from LR to avoid liability. It also could be that critical electronics are just about at that height in the passenger foot well. You would need to raise the axle breathers and perhaps the transfer case and transmission breather was well. You will also want to make sure that the flexible air intake pipe is replaced. I am talking about the one from the fender to the air box. A snorkel will allow you to get over the fender as long as you extend the breathers. However it’s not a boat and be prepared for water ingress if momentum is not maintained.

 

@redwhitekat It is actually in the 04 users manual page 166 maximum recommended depth for wading, it then tells you what to do if wading deeper. It appears to assume the water will get in the cab and high enough to hit the computers and CD changer. Note it does indicate if you stay stationary or you open the doors.

I suspect it is a warranty issue re people who do not know how to do a water crossing. You keep a decent and constant speed and do not stop until clear of obstacle you will fine. Stall or stop in the middle and you may have a problem in deeper water

 

Axle breathers F/R, TC & Transmission breathers are right at intake height and they have curves in them to delay water from gushing directly down the breathers.

 

What Best said, the intake isn't the only thing to worry about. Also a snorkel is only effective if you have everything fully sealed which is not as simple as it sounds with our airboxes. The breather tubes also need to be replaces/extended (up the snorkel for instance) to truly increase wading depth.
