np300 wading depth

nopper · Jun 10, 2016

What is the real wading depth of the np300?
My brochure says 600mm, but most forums say only 450 mm.

And it keeps raining all over europe.

I see a air intake just under the bonnet on top of the radiator, but that is way higher than 600mm.

Water depth is one thing, add a bow wave and that 600mm depths suddenly becomes 800mm :shock:

No need to tell me that. I ride a dirtbike in all sports of conditions. When water gets pushed up by the radiator it is like hitting a wall.

But,... What is the deepest water you would or could cross in a np300

P.s. Not a thing about it in the manual

Playing top trumps we do lose out big style to the ranger :cry

As nopper quoted above, factory-quoted wading depths mean little. Nissan Australia say 450mm for the NP300, which is easily the lowest in class (basically axle depth), however that figure has no asterisks, caveats or fine print. You could park an NP300 stationary in 450mm of water and go for a beer.

The Ranger, which I heavily researched before buying my Navara, quotes 800mm, but only at a constant forward speed of 6km/h in standing water. Unless you drive through a cattle dip, any natural body of water will have a current or motion of some sort and your chances of nailing precisely 6km/h are about zero.

With a water blind fitted and a competent driver experienced in wading, both of these vehicles are about equally capable. The bow wave effect SHOULD mean the Navara's ridiculous intake will stay dry but I have opted for a Safari snorkel, just in case.

I just realised nopper is the OP :facepalm

Anyway to answer your question, without a snorkel I'd be very cautious about anything above axle depth (basically the factory-specified 450mm), but I'd do it if I had to, taking care to keep moving with a smooth continuous speed. With a snorkel, even one that doesn't fully seal the air box (so just something that removes the intake above the radiator) I'd go to the top of the wheels (about 800mm).

A water blind and some careful prepping might convince me to nudge a bit deeper again, but only if I had to.

The limiting factors, once you're not in danger of ramming water into the air box, are the various electronic boxes and the fan, plus the possibility of the diffs sucking water through their vents.

I run a 2019 UK spec Navara tekna with no snorkel and have pushed it to my limits, unintentionally I might add, during a serious bout of flooding in Wales. I can confirm from. Experience, 450mm is absolutely fine, 600mm + with forward momentum is fine for the truck but you are getting wet feet. I did a kilometer push through water up to the top of the wheels and this resulted in about 80mm of water in the cab. In water 800mm+ with a bow wave, over 400m distance the Nissan survived but it resulted in water of about 150mm ish in the foot wells, bringing about un happy seat electrics and very unhappy speaker cones, the door pockets were full and the electric windows are now stiff as anything and the general feel of the running from diffs etc was just rough. Also it should be noted that in 800mm+ of moving water it is was very difficult to make forward moment without being in 4 wheel drive and it goes without saying, a low gear or you will stall in a heartbeat and then it's bye bye bow wave.

Welcome to the forum.

That's some serious wading. I am surprised that much water came into the cab, I wonder if there is a bing missing somewhere?
Worth checking the rear diff oil for water.

Thank you. The door seals were replaced under warranty at Chester Nissan so I cannot complain there but they admitted there is no way for them to test with anything other than a jet wash and thankfully I've never had to push it them depths again. Now I just find myself another route, just like yesterday
