Amarok on Gibb River Road

Regardless of vehicle, the biggest influence is tyre pressures and speed. Stick with highway pressures, and you will shake your car to pieces.stick to around 20 psi and keep your speed right down.

As for the Pentecost, if it is that deep, I would not enter, as it is a wide crossing and the last thing you would want to happen is get into trouble half way across….there are lots of big crocs in the water there.

The Pentecost is usually a relatively shallow crossing. It is influenced by both runoff and tide. Assuming you are crossing well after the wet season it is unlikely to be much above wheel height although it can be pretty bumpy. It looks daunting as you approach as you can't see the bottom and it appears to be flowing quickly. It is also very wide.

The first time I crossed it was very soon after the road was opened for the season and there was a lot of water around. The Pentecost was easy but we struggled across the Durack later that day. It was bonnet deep and that was early June.

Best advice I can offer is to watch others, take it slow and stay towards the centre. Tyre pressure and speed on the GRR are the secret to a successful trip. Be prepared to stop regularly, check tyre and suspension temps, and make sure everything is hanging together.

Safe travels.

When we crossed the Pentecost, it wasn’t deep, a bit long, and we waited for someone else to show us the way. It certainly was less than wheel height, well below doors.
Excellent for washing off some mud and dust. Didn’t have any worries with water along the GRR, just dust and corrugations.

I have a 2016 model and this is my experience.
The 500mm wading limitation is because your rear diff breathers are located in the chassis brace above the rear axle. It's an open ended hollow tube ideal for water ingress. I have relocated mine under the bonnet.

I also attached a breather hose to the duckbill that sits on top of your transfer case and seal it with silicone. In theory that duckbill should not allow water in, but I'd rather be safe than sorry.

Unless you go bonnet deep in water I wouldn't worry about a snorkel because your air intake is under the bonnet behind the grille. Its location also ensures clean air; there's no benefit from fitting a snorkel for dust reasons.

Remember that your air filter box has a duckbill drain. Consider sealing that if you do fit a snorkel.

I run Cooper STmaxx and maintain 26 psi all around on corrugated roads like the GRR.

Hi Bjay,

Firstly, regardless as to whether your air intake is located in front behind the grill or under a wheel arch, when following or being passed by another vehicle on dusty roads, there is always the possibility of getting dust into your air intake. A good quality snorkel raises the air intake as high as possible and gives you the best chance of limiting this dust ingress. Also, making sure the air box is properly sealed.

Secondly, tyre pressures are relevant to your particular situation, what suits one person and their vehicle, may not suit you and your vehicle. It is better to load your vehicle up for travel, and putting it over a segmented weigh bridge so that you know the different axle weights. Then with this information, and the tyre size and construction, go on line to some of the various tyre pressure calculators (G & S Chassis is a good one) to work out the ideal pressure for your individual situation for the various road conditions.

As an example, I run 48 psi in the rear, and 44 psi in the front for highway, and drop to 38 psi and 36 psi respectively when on gravel, and adjust from there depending on corrugations. My vehicle when touring is heavy with a GVM of just under 3,800 Kgs. when towing.

Macca.

You could drive a mini across the Pentecost these days without any trouble as the road has been smooth out and built up somewhat over the years But.. I wouldn't be attempting it when the water is like the second picture LOL :))

I didn’t think the Gibb R Rd was opened until the Pentecost was low enough for “safe” crossing.
