    Radiator Coolant Hose Valve Broken - 2006 Range Rover Sport

    Good day all,

    A Valve of some sort has broken that connects two hose parts in the engine compartment. I have had coolant spraying all over the place. The truck is parked fine at home. I wanted to know if this part that i found broken is simply something i should replace or do i need to find an entire system component including hoses and so forth. Any info, diagrams will be greatly appreciated. Photos are attached.Radiator Coolant Hose Valve Broken - 2006 Range Rover Sport-photo-3.jpgRadiator Coolant Hose Valve Broken - 2006 Range Rover Sport-photo-2.jpgRadiator Coolant Hose Valve Broken - 2006 Range Rover Sport-photo-1.jpg Thanks for the help!

    There are indeed a couple of weak links in the coolant system, there is also a T-valve made out of plastic directly below the engine cover. I'd highly recommend replacing that as well. But other than that, the hoses themselves don't need to be replaced preventatively, they'll last quite a while.

    Just replace with a brass connector from a hardware store we never use that bleed point on the 4.4/4.2 at the dealer and it fails on every RRS/LR3. While you are checking your coolant system check your thermostat housing it there is any coolant residue go ahead and replace the whole assembly with the thermostat. That is another major failure point.

    Hope your doing well!

    Yeah, that bleed T-valve failed on my 2006 as well - made quite a mess in the engine compartment (plus it's under the stupid "vanity" engine cover, which gives you the willies as you cannot see what's leaking that bad until you get to a shop and the cover comes off.)

    It failed on mine too on a trip, but luckily we had a replacement in our group so was able to fix it on the trail...but not much fun trying to bleed a system while out in the middle of the desert!

    I need to check mine I guess. I'm curious why that part is failing like that--poorly cast Chinese crap? bouncing around and hitting something else? or getting cracked when someone tries to open it? clamps too tight?

    Just a piece of plastic, it really should be brass, not plastic as I think the heat from the liquid eats it away!

    Not sure about that picture, but the one I was referring to under the engine cover is plastic. Hard to tell on the one above...

    Just FYI, BPUtah sells the genuine article (plastic...) as well as most of the hoses: https://bputah.com/LR3parts/Land_Ran..._LR027661.html

    Thanks Umberto. Any of you blokes know what size the hose barbs are---so I don't have to take the cover off and find out? I think I'll just replace mine with brass.

    I'll answer my own question...its a 3/8" hose barb.

    So I was looking around for a brass 3/8" hose barb tee with a 1/8" female NPT connection for something like this...

    http://www.jegs.com/i/JEGS-Performan...51108/10002/-1

    and I've given up. So I'm just going to order the OE fitting and treat it as something I need to replace every few years.

    There's plenty of male NPT tee types but then I gotta get a reducer bushing, and it starts to look like a plumbing project gone mad.

    This fit the bill:

    3/8" ID is actually a touch larger than the stock bleeder tee, but the OD is the same.

    do you need to bleed the system when changing this out. 112K on the beast and in this 104 degree heat in Big-D, might be pro-active and change this out.
