[FC] <VV> Carburetor Heat System

[Ken Hand]

 The baffles are only needed in cooler weather to keep the 40 degree air of a cool night from flowing across? the carbs and cooling them down just to keep carb ice from happening. They do decrease the air flow in the compartment slightly. Don't they block about30% of the opening? But, they are both right beside the carbs.

They are NOT for vapor lock only carb ice. Yes, they do control the air flow in the compartment, they keep the cold air off the carbs!

I am familiar with the engine compartment baffles, #3797594, same part 
fits both sides on both FC's and wagons; however, I fail to see how it 
affects cooling air flow in this manner, nor have I ever seen any oem 
instructions as to it's function.  I am of the opinion that we have 
simply considered that this must be it's purpose, without any supporting 
documentation.

I would certainly appreciate any reference to authoritative material 
concerning the purpose of this "baffle".  I think it is more to control 
the direction of the air flow, thus the name "baffle", but wonder 
"Why?"  Noise issues do come to mind, but the baffles do come fitted to 
the pick-ups, don't they?  Maybe they are an attempt to get cooler air 
to circulate throughout the upper engine compartment  and to the fuel 
pump area to help with vapor lock issues.  I just don't know.

Wondering,

Bill Strickland
