CRD, river crossing

Any one could advise on what size of river and how deep a stock CRD can go through ?. I found info for the Wrangler but nothing for the KJ.

Not much further than to the middle of the front grill but by that stage water should be coming in at the doors. Check the height of the airfilter box in the engine bay and you'll see a plastic kind of airdam leading towards the front grill, that's about your limit i guess.

Manufacturer recommends no deeper than 20". I believe it's written in the Owner's Manual.

I went through a flooded road in Gary recently and the water was about to he bottom of the doors. I believe that it would of been fine except a lifted Dodge Ram coming the other way had to be a smart stupid and created a wave that came up over the hood of the jeep and soaked the air filter. the filter got sucked up into the inlet tube and caused alot of black smoke. I was lucky that the MAF sensor didn't get taken out and none of the filter broke off and took out the turbo. :evil:

I think a bridge is the best option for crossing a river but there are some with an 2002 airbox that might be able to go deeper than us with the stock airbox.

If you guys have to cross rivers frequently i would recommend fitting the snorkel and then you can take her in pretty far.

As long as you also extend the vent tubes on the gearbox, tranny and rear diff

Here I am in a water crossing; ignore the stammering attempt at humor at the end. http://www.flickr.com/photos/wlirio/2582993202/in/set-72157605637603477/

I always carry a plastic tarp sheet in the back - in case I take a grubby load(compost from the garden centre or stuff to the dump). You can stick one side under the bonnet (hood) to secure it, and the bottom edge lash down under the bumper with cord/elastics. Covers the grille and intake, and provided you keep up a steady speed and a sensible bow wave you should be ok. If you keep going, you probably won't even get much through the door seals. Check diff & transmission etc oils as soon as poss afterwards.
If you're going to be fording regularly, then snorkel, and extend the breather tubes, and have your door seals checked. You might also want to think about fitting a screw - in drain plug under the mats/carpet - just in case:))

The rear diff breathers are about level with the top of the wheel

I followed a Wrangler with water over his 33" tires and made it with no trouble. I kept it slow so not to build up a wall of water in front and it was only about 3 car (KJ) lengths long. I think I was lucky and should have taken it in reverse instead.

Please, PLEASE, tell me that's not sea water!

I'd say that is a healthy dose of OCEAN in and around that Aussie KJ.

On a stock '05+ you don't want the water to come higher then halfway your front bumper. If you create a wake it may enter your air intake and then your engine goes 'boom'. First thing I would do is fit the bottom half of the '02 airbox with the mini-snorkel.

Please bear in mind that if you drive a manual into deep water that will also come into the belhousing flooding the clutch. Your clutch will not like you for that..Make sure to drive it for a while so it can dry of. If not everything will start to rust and clutch failure may arise...

Sorry, can't do that. Unless you want me to lie.

Fraser Island, Queensland. The beach is called Seventy Mile Beach and is 4wd heaven. Until you make an error of judgement, of course.

I mean can anymone with as little mechanic knowledge like me could extend these vents ?

Cheers

Hi Tony!
You mean that the 02 airbox is safer than the 05? In this case, with extended vents and an 02 airbox, i should extend significantly my diving ability, no? ...(not sure the on-board computer will indicate the decompression steps while surfacing... ;-)
