Regards.
I have always wondered, what is the limitation of a DEFENDER to have a wading capacity from just 500mm. Compared to a Range Rover for example, being much more technological and a wading capacity of almost double. 900mm. thanks.! |

I suspect it's the breathers for axles, engine and gearbox. With very little extra preparation the defender can go a lot deeper than 500mm.

Air intake on the wing, hence snorkels are so popular.

And for the td5 you have to consider the location of the ecu in the seat box. Fairly easy to relocate to a higher position I believe. Presumably the same for the puma.

Td5.
 Click image to enlarge Just drive it properly. Get a bow wave, and don’t hang about. Never caused an issue with any of my electrics. |

The ECU on the TDCi is on the bulkhead behind the engine at cylinder head level and is actually quite well protected.
I have had my Puma in a ford deep enough to have water over the front wings and up to the door handles on the upstream (driver's) side. The only ill-effect was that the carpets got very wet, however it would have been different without an RAI since the original wing-side air intake was underwater. As landy andy says, if you know what you are doing you are unlikely to have any issues unless you are a complete nutter. I did one manage to fill my wellies whilst driving my S1 80" through a flood, the water inside the cab was just over the level of the seatbox. Even though it was completely standard and has a petrol engine with spark ignition and a mechanical fan, it caused no problems whatsoever (except to my socks) because the vehicle was properly set up. The distributor on the 1600 and 1997cc engine is right at the top, and the fan belt slips when wet if properly adjusted. The bow wave keeps the level in the engine bay about 18" lower than the level ahead of the vehicle. |

I thought I’d bump this thread as it’s a bit topical at the moment.
I was all set to take my 2.4 TDCi thogh our local ford flooded to 3’’ / 900mm, and was wondering what the limit was. In the end it was blocked by a stalled car and van, so no chance to find out. |

Nothing like a salt water bath to accelerate the corrosion of a chassis and everything else! The on line MOT history for the 90 looks interesting

Three feet of water shouldn't be a problem in a standard Defender as long as you know what you are doing, but equally it is deep enough to do serious harm if you don't, or if it is fast-flowing. |

Also remember that your alternator is mounted quite low in the engine bay. If you do any deep water fording, please remember to dry out the alternator by keeping the engine running a bit before shutting the vehicle off. Otherwise, you may damage or seize the bearing and screw up the IC
