What's this thing for?

On a US spec LR3 SE V8 there's a small (4 to 5 mm diameter) tube vertically just behind the left end of the radiator. The tube has a cap on it, and goes straight down, jogs over, then goes out of sight. It is near the radiator coolant overflow tank. Sorry I can't post a picture.

It is "near" the coolant overflow tank or attached to it???

Not knowing, but my guess is it could be the coolant overflow pipe which takes any overflow cleanly out to the bottom of the engine bay. Antifreeze in the coolant system is pretty corrosive to paintwork.

I am sure some of the more knowledgeable bods on here will give a definitive answer though. Life is what you make it.

It is near the coolant tank but not attached to it.
It does not appear to be an overflow. I'm guessing it could be a vent but for what? It has a cap I could turn but I didn't.
