The Range Rover L322 2010 TDV8 4.4 is known for this water leak fault.
I was out this evening and a radiator hose four way branch coupling on top of the engine inexplicably broke and water was everywhere.
The dashboard lit up like a Christmas Tree, not charging, restricted performance, coolant low, etc.
On opening the bonnet the culprit was easily visible right on top.
It took frequent stops and 9 litres of water to get the 10 miles home.
Of course you can’t buy the coupling on its own. It comes with the surrounding hoses only and costs about £80 (part number LR029140 seems to be it).
I’m not liking the idea of £80 to replace a tiny bit of snapped plastic. I think I’ll repair it. here’s how I did that.
As I have a couple of stents I reckon a stent would work. The joint doesn’t seem under a great deal of pressure, so I’m hopeful it will last.
