Thread: preparing a 03 TD5 Discovery for water crossings

Water in the ECU does that.

I stop at the edge of the water now.... and then drive in and as long as you dont stop it should be ok. If you go in too fast the fan will hit the radiator and thats a pain.

You may also want to check the seal on your airbox (Duckbill from under the guard) as it will probably leak despite the snorkel.

Use a blind for deep crossings, and do as Slunnie said, slow in not too slow, then create a bow wave, i use 2nd low range.

Baz.

There aren't that many sensors that will stop the engine.

Water inside the ecu will do this. There are a few drain holes in the base which it can fill up through. It does normally take a reasonable amount of water in it to actually stop the engine.

smaller amounts can cause other issues. no throttle response etc.

The crank position sensor has the ability to stop the engine dead, but is 100% waterproof.

The throttle pedal also seems to be completley submersible without issue.

Most of the other sensors, eg MAP and AFM, can be unplugged with the engine running and it will not stop.

Bad signalls to the injectors could also cause it to stop. I think this is part of the reason it stops the throttle if it thinks there is an issue, as the engine will keep running.

As has been said a sensible speed, and a tarp should be all you need. We saw a D2 TD5 up the cape just with a snorkle and mud tyres and he had driven through all the creeks without any prep work.

Hi,

well I had a couple of little swims recently in my TD5. The only prep was a snorkel (day before i went lol) and ALL breathers go up into the snorkel now. 3 of the 4 are already high up in the engine bay, but the rear axle just sits up in the rear wheel arch, that now joins the others at the bulkhead and goes up the snorkel to.

I don't know whether you guys would consider this a "deep" wade, but have a look anway...

If its touching the bonnet then I consider it deep.

This was a pic at Cape York near the start of the OTL. It was just before a hole put water up the windscreen. It was the deepest water I'd driven in.



ok, just uploaded the vid, sorry for the delay at the start.

The tide line is on the snorkel as I came out.

what about the ecu under the passengers seat if it is an auto ?




you wouldnt want to go much deeper than this without a snorkle

there was water in the airbox after this crossing but...luckily.... it kept going


cheers

lucky i missed that deep hole.....didnt realise it was same spot til after i posted

i'd like to know if anyone has drowned that ecu under the pasengers seat


cheers

Warning, Check that your snorkle is water tight. where it comes though the side to the air box those joints may leak. I have placed a clip on the drain under the air box as well.
