If you fit a snorkel, what then is the limit to how deep you could drive through water? Accepting the safety issues about not knowing how deep it is and not going through deep flowing water, what becomes the limiting issue for the depth of the water?

Depends what truck you've got.
On a TD5 the main ECU is under the driver's seat and the battery is under the passenger seat so fitting a snorkel raised air intake achieves little in terms of wading,
Then again, they're intended for keeping out dust, not water.
Other issues regardless of engine/year etc are axle/gearbox breathers and electrics.

Technically, it DOES NOT change the wading depth. Granted, a well sealed RAISED AIR INTAKE (They're called raised air intakes, not snorkels) will prevent water from getting sucked into the engine but that isn't the be all & end all.

The other considerations:
  • Breathers
  • Ail seals
  • Electronics
  • Buoyancy
  • Flow

Thanks for the replies - point taken about the correct name!

The vehicles are a Discovery 4 and a Freelander 2. Both are unmodified!

My question was raised because some of the replies I sort thought I knew, but you still see pictures of what look like standard cars doing passable impressions of a submarine! IF you have a reasonable idea of the terrain (roads you drive down / cycle down regularly that are now flooded but you know how deep the water is) how do you know what is going to be OK and what is going to get you looking like a prat as a tractor has to pull you out? The wading depth quoted seems to bear little resemblance to what you see them being driven through. So how do you guys who really know what you are doing in a Landy know when to allow discretion to gain the upper hand on valour when faced with a load of water?

Sorry if I'm not making myself clear.

By the way - could someone enlighten me about "breathers"?

Thanks again

What those pictures don't show you are the repair bills afterwards!!! All it takes is for one wrong move and you have instant & catastrophic failure, together with a bill for a replacement engine.

450mm & 700mm don't sound like much but it is deep enough. Try & stick to those limits. wink

I have no experience of Freelanders but do not take the Discovery any deeper than the top of the wheel rim. The alternator amongst other things is surprisingly low down.

Also unless wading in clear water, get the car up on a lift and wash off the underneath thoroughly afterwards.

We took our Disco 3 to a days off road course at Land Rover's own facility at Eastnor Castle a couple of years ago which included some wading. Having recently had some unrelated major work done on the car the technicians showed us the error of our ways whilst the car was up in the air.

Just for a frame of reference - a complete replacement TDV6 for a Disco 3 is £4500 + VAT plus approximately 24 hours labour plus vat to fit (it's a body off job).

Don't ask me how I know. Happy Christmas. cry

How do you know?

(you asked for it, you said to not ask. This means it HAS to be asked)
I'm guessing the g4 disco in the air on a 4 poster ramp is related then.

So, 08 plate engine, crankshaft failure? Belt related?

4 year old car, 53K miles. A week after a 60k mile main dealer service and 11 days out of warranty, catastrophic engine failure, starting at no5 cylinder con rod big end bearing. LR customer services believe 53K miles is perfectly acceptable lifetime of an engine, we disagree, it's with the lawyers.

There's been a few reported issues with bearings and crankshafts on 07+ engines on disco3.
Best of luck with getting it sorted out.
