40/41 Pickup-Heater Ducts/Vents

[bullrunmotor]

Did Ford equip 40/41 Pickups with heater/defrost ducts in the dash or were they part of heater kits installed by the dealership or others? Thanks

Yes, there are cutouts directly below the windshield garnish molding louvers to admit the warm air for defrosting. The defrost nozzles connect to those cutouts. The 1940 truck cabs have a smaller cutout than the 1941 cab. Correct defroster nozzles for these trucks are different from those used on the passenger cars. The truck nozzles are curved and difficult to find. Good luck.............40larry

Oval slots above instrument and glove box hole are where nozzles install. This is a NOS cowl for 1942-1947, 1941 is the same.

I noticed my 40 tonner panel has tiny little slots, not even 2 fingers wide and the 47 parts truck has much larger ones. When I have the windshield out I am going to enlarge them to the larger size. Good defrosters are pretty important where I live.

Here is a photo of a 1940 pickup cowl with the smaller version of defroster die cast ducts,(same as 1940 passenger cars) the one with X was removed from this cowl. The duct with masking tape is the tin or steel type used on the 1941 to 1947 Pickup/truck cabs. The NOS cowl shows larger defroster opening of 1941-1947 pickup and truck cab.

I removed this from the upper footwell, passenger side of my 41 3/4 ton. the hole in the firewall was drilled out to about 2" diameter, using multiple 1/4" drills in a circle. Clearly a hack job. No heater or ducts in the truck when I got it, just this. Any idea if it was part of a typical heater at that time?

The flex metal tube and outlet ducts were part of the heater kits.

411ton, that is the plenum for the hot air heater not the hot water heater. That being said I would think they used the same defroster nossel. If my grey matter is corect I think the hot air type used flexible steel for the defroster ducts. I liked the hot air style heater best but it wouldnt work with my fenton headers. Tim
