Was driving in to town today and one of the roads was severely flooded, everyone was turning round because they were in normal cars... It is a fairly long stretch of flooded, flat road about 1/4 of a mile.

The initial marker said 2.5 feet deep, no problems I thought, I drive this route every day to work and back so I know the road, I know from experience that the RR can easily cope with 2.5 foot of water.

Get to the second marker and it's at 2 3/4, starting to worry now as I can see logs stuck in the hedge and I didn't realise the road dipped down, I assumed the first marker was the depth of water along the whole road!

Get to the third marker, the water is at the 3 foot level. At this point I'm beginning to run through my mind how I cant afford to replace the engine and all the interior! But slow and steady with a nice bow wave in front of the car, the water was level with the top of the bonnet but was a good 1.5 foot lower behind the wave so I'm sure the water wasn't in danger of getting into the air intake.

By the fourth marker we're back to 2.5 feet, massively relieved and carry on like it was no big deal. My passenger was in awe, as well as the people who were at the other end turning round.

Another good day to be a Range Rover owner `)

I drove home a different way! It could have been bad, if I'd had to stop for any reason ie a log in the water, or under the water and I'd lost my bow wave I would have been screwed. I also think that if the water had been much higher the car would have thought about floating at the rear and I could tell it was hard work to push that much water out of the way.

So the manual says 0.5M, yet 0.91M is possible!

Nice story;i wouldnot try myself really.
We hit a rock last year since we couldnot see what was under the water,we were in the woods.
Help was miles away.
After being stuck there a while we were able to get out.

Cool !! mines been up over the bonnet. Cut out and towed out of deep water too... I have the silt left in the spare wheel well to prove it heh... just keeps on running.

I would be sure to inspect your differential at least... if you took in water either through the breather or just being forced through the seals by pressure, you could cause damage by driving it very far afterward. It might not even be a bad idea to check the transmission/engine oil too although those are less likely to have taken in water. Some people modify their breathers to move them up higher, but that still doesn't necessarily prevent the issue entirely.

I can't see where the breathers terminate and it's not mentioned in Rave as far as I can see. On the P38 they terminated on the top of the bulk head so were well out of the way of water, they were also looped at the top so that water would have to go upwards first, as far as I can see in the manual the gearbox breather runs along the top of the box and up the bell housing to the back of the engine.

I'm sure all will be fine, the bow wave would have meant the water level in the engine bay never got above LR's recommended 500mm. Unless someone comes back and tells me they terminate somewhere really low down I'm not going to panic!

One side effect has been that all my lights are steamed up - I'll make sure I drive too and from work with all lights on over the next week. The trouble with HID is they don't that hot (don't even melt the snow) so will take a while to evaporate all the moisture out. Should be OK with the fogs though as they use a proper bulb. I might take all the lamps apart next weekend and check for any water corrosion and lube them up with some WD40 in the sockets...

Yeah, I don't know what the risk is with this specific vehicle, but I know some people who do serious 4x4 and they usually check/change the differential oil after any serious water crossings. I guess they figure its better safe than sorry. Another factor is that most of these guys drive old beat up 4x4 and perhaps the seals aren't in great condition either? I'm not sure what sort of pressure it would take for water to breach the seals.

Dan,

Out of interest, did you select low range first? Just wondering, the only time we encounter that much water on the road over here its solid!

No, I should have and then locked it into 2nd. One doesnt want a gear change when trying to maintain a bow wave as it can disrupt it or loose it completely. I find in low range it hunts between 2nd and 3rd at wading speed.

I did raise the suspension though!

Actually, I just realized why water could get in regardless of extending the breather... if you have a hot diff or transmission, etc from driving... and then you plunge into cold water, it will cause a rapid reduction in air pressure inside (maybe faster than the breather can allow air in, and most definately if the breather is submerged) possibly causing water to be sucked in though the seals and/or breather. Like those middle school science experiments we all probably did, heating an empty soda can and then dropping it in water causing it to implode.

Good precaution to let the vehicle cool off while walking the water crossing and inspecting for hidden obstacles, etc.

Never had a problem in the past with this..... and wtf is the point in having a Range Rover if you have to get out and walk through the river first!

Standard procedure actually.
It's why I took a drysuit to Iceland with me. You never know what is under the
water, although if driving a flooded road, one could safely assume that there are
no hidden obstacles.
But you know what they say about assumption. :wink:

Unfortunately I don't keep waders in the car, or a dry suit.

I believed all that was nesasery was a visual inspection from my heated seat, knowing full well that there was tarmac at the bottom, with the exception of the log I drove over.

Yeah, I'm with you! If you go far enough off road it can be slow going and a lot of work if you do it carefully and take every precaution. I don't quite understand the draw of doing off road trails so difficult that you could probably walk/jog the trail faster (when you consider all the spotting and planning it can take to avoid damage/injury/getting stuck). I tend to enjoy enjoy trails where there may be a few difficult obstacles but you can mostly drive at a reasonable speed (at least 10 mph), otherwise I tend to get frustrated and/or tempted to get sloppy and make a mistake.

Your lucky to have so many great and varied trails in the US, over here we are banned from driving on nearly every green lane that exists!

Yup and if it rains or snows the police tell us to stay at home..... Because everyone stays at home they never get any practice with driving in snow,wet,icey conditions and when they have to drive somewhere they immediately hit a tree!

Dan, I saw you wading that flooded road with a bow wave for protection the other day and took a pic:



Look at the vastly reduced depth behind the wave its barely over the side steps...

Go deeper next time and use the right gears!

Dan last year the road in front of my shop flooded, it was under an overpass, cop stopped traffic... 5 min later he waved a land cruiser and myself up to pass through the puddle... Land cruiser out front, I followed a few seconds after... The land cruiser water logged right in front of me, and became stranded, water started cresting at my windshield... I thought for sure I was all done, but I kept going, must have been 4'. I made it!

Both front headlights shorted, it screwed up my AC compressor, and it did something to my alignment... but I made it `)

I'd be bricking it at 4 foot! The deepest I'd been in the L322 until this time was 0.5M http://www.youtube.com/watch?v=is4NWB81QOU
