TRUCK 6 CYLINDER. WHATS THE COOLANT TUBE UNDER THE INTAKE MANIFOLD CALLED. IT GOES TO THE FIREWALL AND THEN THE HEATER COIL. IT'S METAL. I NEED TO REPLACE IT BUT DON'T KNOW WHAT IT'S CALLED.

I'm replacing a blown head gasket and notice a lot of corrosion around this pipe. It's metal. Thanks

If this coolant tube is connected to the intake manifold could be to cool it down and also used to actuate -TVSV to transfer vacuum to certain vacuum operated devices-
