Can the TDV6 handle a hose down (wash)?

[twr7cx]

Any issues with hosing off my TDV6 with the top plastic cover removed to clean the last 6 years of dust off? Anything particularly worth covering or avoiding?

It would be really sad if it couldn’t.

My understanding is you need to be careful of pressure washing around the ECUs that are on the bulkhead behind the main battery, I have not had any issues washing mine but I just use a hose and not a lot of pressure .

NO dont do it - wipe down only. The ECUs are designed to deflect water from under but not from the top.

If you wash/pressure wash your engine as a minimum you will have major transfer case issues as the ECU behind the battery is not water proof.

You have been warned - all LR forums had threads about neebies (including from me a few years back) washing their engines and suffering the consequenses. It took me a week for my ECU to dry out and it is a pain driving home with your tfr case stuck in low range - the wet ECU not me put it there.

Plenty of posts on the facebook page with tales of woe from people pressure washing the engine bay, normal hose should be fine.

Might be better to spray degreaser on the dirty bits (avoiding the ECU) and then hand wash it with warm water.

I clean the engine bay as follows;

Pop out headlights and grill for a mega job

1:10 or weaker CT18 mix sprayed by pump bottle lightly over all surfaces in nooks and crannies.

Engine cover left on as with all covers.

Leave to dissolve red dirt for 15 minutes.

With the hose crimped, lightly wash (splash) off CT18 - no pressure whatsoever especially to the back edge of the battery box

Chamois off excess from airbox and engine cover around oil cap.

Engine bay will be spotless. The CT18 wash does the work.

I don’t try and remove dust or wash under engine cover.

A D4's transfer case ecu is somewhat protected inside the RH box but a D3's TC ecu is unprotected over the back of the battery box.

I don't do it anymore, no need to ask me why...🤬😯😯

Ok, glad I asked. It’s only a tad dusty under the cover so a brush off and wipe with a dry cloth will be good enough.
