Blower motor vent tube

[1978C10]

1978 c10 replacement blower motor has smaller vent tube hole. Should I just plug it. Can't find vent tube anyway.

I would not cover the hole if you use the blower motor alot, may cause the motor to overheat.

Pressurized air is supposed to be forced through that tube to cool the motor I'd improvise ,maybe some plastic tubing and 90 degree spark plug boot.

plastic wire loom wrapped with rubber tape to fabricate a replacement, use dumdum at both ends and done

Ya, like said - you need to make a ducting to push air into that hole or the blower will overheat.
