Works for Land Rover
This fits the bleed valves on LR4 and probably loads of other Land Rover vehicles. As far as I can tell, LR will not sell just the bleed screw so buying from Land Rover means buying the entire hose assembly. If you have to bleed your coolant system you will need to use these bleed valves and after several years the plastic screws become brittle and fail. These are ideal replacements. After experiencing a nice fountain of hot coolant, I now keep a couple of these as spares in the car.

DIRECT REPLACEMENT FOR OEM PART ON 2012 MINI R56-S.
Order this to replace the snapped part on my R56-S. Had to heat a phillips screwdriver with a torch and press it into the center of the remaining part of the old screw until I could create something to grab. Took a few times but finally was able to turn it out with screwdriver without damaging anything else or taking a ton of stuff apart. Once out, this new unit went right in with no issues. Sealed up great! I have an extra now but hopefully wont need it soon.

Did not fit
This was to small for a 2011 chevy cruze with ECO motor, need to order the white gm one for perfect fit, nothing wrong with the quality of the item or the service, was a good part if it had fit..hope this saves someone else the trouble of finding one that works

I replaced my thermostat in my 2013 Jeep Grand Cherokee and damaged the bleeder screw and o-ring. I thought I would have to replace the complete OEM thermostat. These saved me. Fit just like the OEM. These come with the orings. And one spare bleeder assembly for the glove box!

I don’t think that the amazon vehicle match is accurate. I bought this and it fits my 2005 bmw 320i. It was a very convenient and easy fix instead of replacing the whole hose.

They fit great in my 2000 bmw 528i and I have had them for a couple months now and they have had no issues.

Doorman is a good product but unfortunately these will not work for the bleed screw on the coolant expansion tank on a lr3
