If I understand the 49-52 truck service book correctly the fresh air heater wasn't available until 51. On my 49 F4 cab there is a rectangular knockout and three knockout holes (not punched out) on the passenger side of the cowl under the fender. The fresh air heater used these holes for the fan mount and fresh air duct that went to the front of the truck. I guess my question is, was these holes used also for another type heater in 49 or was Ford planning the fresh air heater earlier than 51 and had the knockouts already in the cab for it? I have the original three door heater restored and installed in my truck so I'm not looking to change, the knockouts on the side of the cowl just has me curious. By the way, the switch and defrost cable for my truck heater are the same as the late 46 car, tan-grey with red lettering, but the dash bracket has the switch and cable reversed from the car. The heater looks like a car heater but it is rotated 90 degrees from the car heater and the three doors are orientated differently. Thanks, Mark Poley

Heaters for Ford and others were made by a variety of manufacturers, and generally installed at the dealer level. My '47 Ford had a heater in it that resembled those in the Chevy trucks. Now it has the more typical three door type, of course. A good many vehicles used the Southwind heaters because they provided instant heat well before the hot water heaters could begin to defrost your feet and the glass.

Here is a photo of the side of the cowl showing the knockout for the fresh air heater. I'm curious as to why these are on a 1949 cab if the fresh air heater wasn't available until 1951 Thanks, Mark This message was edited by 49fordv8f4 on 8-12-13 @ 6:55 AM

Most of the shop manuals out there were printed in 1951 with a suppliment for 52. The pics in there were of 51 model trucks. The Magic Aire heater came out in 1948. They used that version from 48-50. In 1951 a different version came out with a slightly different version for 52. My 1950 has a Magic Aire and it uses all the factory knockouts. It has a 1948 mcab on it. I've attached a schematic from the Parts Catalog. Barry 50 F-1

As Supereal says, there were alot of aftermarket heater sold back then. THe dealers sold them because the profit margin was greater than a Ford dealer installed kit. I did Ford parts for 30+ years starting in the 70's and we had alot of non Ford accessories and sold a ton. Especially radios. Sears, Montomery Ward, Firestone, Goodyear, JC Whitney, western auto and others all sold heater kits. I've run across quite a few of these in all the 48-52 trucks I've torn apart. Never saw one with a Magic Aire. It was a truck and you did not spend alot on extras back then. Today, it's all different. Barry 50 F-1

supereal and Barry thanks for the replies. As you both mentioned, I too have had a number of 46-51 Ford trucks and I don't recall ever seeing two of them with the same heater, most were also aftermarket. Barry, after reading your reply I went back and looked at the service manual again and realized that I wasn't reading it correctly. As you said the fresh air and recirculating heaters were both available 48-52 but, changes had been made in 1951 with the elimination of the in cab water control valve. I guess when I read that I took it to mean that the fresh air heater was only available after 1951. Thanks for the correction. Here is a photo of the heater in my truck. Thanks again, Mark

THat heater was offered as a dealer installed accessory. They were originally from earlier year model Fords and was brought back in 48 as an accessory. Barry 50 F-1

My three door heater looks like the three door heaters in the earlier cars and trucks with the exception the early heaters were mounted horizontal (they were wider than they were tall) and mine is mounted vertical. My heater has the two top doors both hinged on the right side of the door and the early ones the top doors hinge in the middle so the doors open from opposite sides. The bottom doors open the same mine is just shorter. Thanks, Mark
