Default Re: Coolant port on intake manifold

You are picturing the flow backwards. There is no overflow in this system.

Coolant is constantly flowing through that hose when the engine is running. Flow is from the engine near the intake into the tank on the fender. It de-aerates the coolant (system is self purging) from air bubbles that constantly form from cavitation. If you disconnect that hose and dump the coolant, the system will empty in a minute or two as you will be dumping all the coolant.
