66Conv200

I have a 66 Conv 200 cid engine question...

There is a coolant hose that provides hot coolant water to my heater core that goes through the base of the carb plate spacer. The hose connections are becoming corroded at each end and I'm considering just running the heater core hose around it altogether.

What is the purpose of the coolant flow through the carb. I looked it up in the service manual and could find no mention of it's purpose.

Do I need it?

I believe that heater hose is a type of heat riser, but im not sure.

From the Ford Service manua "To prevent carburetor icing at the base plate, a spacer, heated by engine coolant, is located between the carburetor and the intake manifold. The coolant flows from the front of the engine through the spacer inlet hose into the coolant spacer and into the heater hose to the heater core"
I would just replace the hose and clean the connections. The corrosion is normal on cars that the hoses/coolant hasn't been changed in as often as they should.
