Hello. I'm not sure what this hose is for or whether it should be connected to something. Hose is pictured to left of the expansion tank and sitting on top of radiator. Much appreciated. Rob
It looks like the vent hose from the carbon canister which is not connected to anything but, on mine, it sits between the radiator and the body, pointing downwards.
That's exactly where mine was when I noticed it. Thanks both for the replies.
