> [@Bakhtyarsp15](#): > > could you guide me about air vent of the radiator; where it is located? There’s no air vent in the radiator, otherwise it would leak. There’s a tube between the radiator’s neck (where the radiator cap attaches) and the overflow tank, do you mean that? I think you are referring to my post above. That’s the small air vent in the plastic overflow tank, usually in its lid. ---

Sorry! The expansion tank is only marked with “full” and “low” mark, maybe they are the cold and hot. [Previous page](https://community.cartalk.com/t/coolant-leaking-from-exapnsion-tank-weep-hole/190245.md?page=1)
