Ah somebody with a proper diagram! Yes that appears to be the part. All the diagrams I found were so coarse in their fidelity I couldn't discern this part name.

Any idea where I would find a part number for said item?

Thank you,
Tim

LAND ROVER THERMOSTAT HOSE KIT RANGE LR4 RR SPORT 5.0L LR049989 LR045238 OEM | Miami British Corp.

Always call to verify, but I think that is what you are looking for.

That looks like the ticket. Thanks!

Not the ticket.

It turns out that the upper half of the diagram is the part number mentioned, and the part in the lower half which is what I need.

This is a very confusing diagram. I'll attempt to return the parts and get the other pieces ordered.

Sadly, the only part I need is the plastic piece that fits the small hose into a 3mm hole in the front of the water pump. I would have robbed that off said part but $122 for a small bit of plastic, just couldn't do that.

Not impressed with LR parts manuals!

For future reference, what part number did you get, and which of the hoses in the diagram did you get?

I have no idea.

Unfortunately trying to communicate with JP at Miami British proved to be too difficult. I even sent a print out of the attached diagram from their site when I returned the part indicating what I need to replace. So I don't know the actual part I need. All I really needed was the plastic backflow valve anyhow.

My LR4 has the lower green parts (two smaller hoses) and not the larger ones on top. JP was adamant they were the correct parts and is sending the same part to me again.

I guess I just paid about $130 for a $5 part.

Once running it is off to the dealer for trade in for something less problematic. I just don't have time for this. Had enough plastic parts on motors and replacing other parts with 'who cares' level of dealer support even on TSBs that are black and white.

Such a great vehicle design but the gremlins are just winning on this owner over the past 3 years.

I'm half-way through this job on my 2011 LR4. Disassembly is complete, tomorrow I will re-assemble.

First, thanks for this thread! It really helped fill-in the missing info from the shop manual.

Here's what I can add:
- the bottom left side of the radiator has a quick-release connector for the transmission cooler line. This is the easiest drainage spot. You do need to remove the small plastic protector near the wheel-well to access.
- the fan can be removed with a universal fan kit. You don't need the Land Rover tool. I used this one:

Where did you find the shop manual? I haven't been able to locate one.

Here:
Discovery 4 Workshop Manual - Land Rover Forum in Africa

The shop manual is over 5000 pages long. I cut out the "Engine Cooling - V8 5.0L Petrol" section and saved to my tablet. It's only about 45 pages long and I think it starts around page 1294?

Atleastbehandy thank you so much, I've been looking all over for one of those, obviously not in the right places. Thanks again.
