I have an LR3 and the small radiator return hose that goes over the engine with a plastic T-valve with a metal cap is broken? Does anyone know what this part is called and where does this line go? The part has norma and r 1/4" labeled on it...

 

Can you snap a picture? It would probably help identify it better.

 

Thanks for the help... It was the cooling system bleeder valve.

 

the dealer sells the tee now instead of the whole damn line.

if the cap is still good you can remove the oring and use sealant to seal it up and you will be fine. just bled the system of air by opening the plastic screw on the bottle and waiting till the air stops coming out. just remember to install the regular cap.
