[Farmall] 1944 Farmall B Question

[Mike Sloane]

Make sure you get a non-pressurized cap - the thermosyphon system on the 
B is not supposed to be under pressure, and using a pressurized cap will 
cause it to boil over. Also make sure that your radiator fins aren't 
clogged up with leaves/trash. Another thing that can cause overheating 
is a loose fan belt.
