Changed my water pump and front and rear crossover tubes on my 2013 5 litre. The small bleeder screw on the heater core pipe did not survive the operation; I can tell it was cracked and hanging by a thread. The only official fix is a new pipe. The screw is not available from Land Rover. There was even a retiree at the dealership (former tech?) who said, "Yeah I've replaced a whole bunch of those in my time. I don't know why they used a cheap plastic part." I have a feeling there is a bin in the back with about a gross of those little plugs, but I can't get one.
So here's my question: Back when I was working on the Disco 2, there were all kinds of tips and tricks, like "Oh, you need a window roller? I bought one at Home Depot that worked perfectly, part number...." Since I cannot get just a bleeder screw from Land Rover, does anyone know some genius hack that will work perfect, like, "Get a Dorman part number...." or "The bleeder screw from a 2008 Jaguar XJ is the same."
Help! Please!

 

I think these BMW parts fit.


For the price worth a try?

 

Mine arrived same day as your post. It does fit perfectly.
