Thread: deep water crossings

I was wondering the same. I assume that you cannot cover the front quarter panel vents and likewise, you cannot allow water in these vents????

well i dont own the d4 ,,,but experience tells me ,,covering front/grill with tarp /canvas creates a barrier effective enough to produce the classic bow wave ,,which in turn lowers water level ,,vehicle confronts as it sails along thru the h2o ... in theory stopping most ingress in eng bay ,,, and pulling you along to a small degree,,,, etc etc a good practice regardless of snorkel fitted ,drive in hard enough ,,on a bad day and you can be unlucky to bend something ,,like fan into rad/cooler etc etc...... this theory all turn to crap when you manage to get stuck in the drink,,,,,,,

I like the idea of keeping a bow wave and its resultant air cavity in the engine bay. The thought if dry bearings, electrics and such is appealing to me.
In a working week our fleet of Defenders can do up to 12 reasonably deep crossings each, by that I mean over the top of the wheels. We rarely replace tensioner idler bearings or have any other water related problems.

The D3/4 will produce a nice bow wave about a metre off the front for crossings up to the 700mm limit. At this point, the low point of the wave is conveniently directly below the air intake vent. The bonnet seals work very well and will trap air in the top half of the engine bay as long as your moving.

I used to fit a polycarb screen (that I made up for the purpose) to the front of the D3 when in comps, but that was more to keep mud off the intercooler than to stop electrics etc getting wet.

RAI for the D4 also has a kit available to seal the ducting.
D3 has proven capable of very deep wading even with the old RAI.
Weakness in D3 is the transmission module behind the main battery, it was moved to the second battery box.

What is this sealing kit of which you speak? Got a part number?

LRO13711 is the hose and PHD000714.

Thanks CaverD3.

So from the Disco3 site I can see that the elbow and hose are now waterproof, but can't seem to find a conclusion as to if the whole system is waterproof? Any thoughts?
