Offroading

see that snorkel looking thing on the front of the car? Some cars come equipped with this and it lets the engine run if it is completely submerged in water. That driver does have some cajones, though.

I used to do alot of 4wheeling and came across alot of snorkle rigs, but there is more to it to do it right (and I saw alot of fails).

The Engine fan becomes a propeller in water and can actually pull itself into the radiator, it needs to be disengaged or turned off if electric.
The battery and ignition system needs to be sealed and protected against water intrusion.
The differentials and transmissions are vented and if water gets in them the fluids need to be changed ASAP, vents should be relocated higher like the snorkle.
Wheel bearings need to be repacked soon because the water mixes with the grease.
And modern vehicles with electronic ECUs need to be sealed.

If you just add a snorkle and think you can now go anywhere there is a good chance you'll break down a few hundred feet after the water crossing.

Land cruisers are shitty to begin with...

Ah NSW.. feral is as feral does... LOL

L.M.F.A.O. Who ever wrote "Passenger: Don’t drive through the water! You don’t know how deep it is!
Driver: This is a Land Cruiser -we’ll drive right through along the bottom, mate.
Passenger: But what if it floats instead?
Driver: No worries, the engine will just shift into jet mode."
clearly has an understanding of Australians.
