No. All '40 Fords were equipped with a dual core radiator with the fill off center. You have a later, (service) replacement radiator.
All radiators for the 1940 model year were of the split core design. A metal reinforcement was placed between the cores providing protection to the tubes and fins should the engine crank extension be utilized. All cores were brass, oval tube design. The number and pattern of tubes and fins varied among the various manufacturers. Radiators were produced solely by the Ford Motor Co. until approximately March 1, 1940. Radiators were painted M-1706-A Flat Radiator Black.
The filler cap was on the left side. The overflow tube was soldered to a cap at the center of the top tank. This tube was routed along the left side of the tank, and then downwards, soldered in multiple spots to the left baffle. A “U” shaped channel was soldered to the rear of the radiator below the upper hose nipples. The headlight wiring was subsequently routed within this channel.
Radiators (91A-8005) installed with the 85 HP and 95 HP engines had “91A” stamped in raised letters in the top tank near the left or right hose nipple. Beneath the “91A” was a stamped line and just below that the manufacturers identification. Ford radiators had either a “D” for radiators produced at the Dearborn, MI. plant or “G” for radiators produced at the Green Island plant. These radiators were 3” thick, had four rows of staggered tubes and a total of 38 tubes per row.
On March 1, 1940 Ford began to supply the McCord Radiator & Manufacturing Co. and the
Modine Manufacturing Co. with the upper and lower tanks as well as the baffles. These companies in turn installed these pieces on cores of their own design. On occasion the suffix of the core design was identified. An example would be “B1” for Ford, “B2 for Modine or “B3” for McCord.

Hi Sid, It sounds like you may have a 41 pickup radiator as you have described the one in my pickup perfectly. Tim

It appears as if you too, have an incorrect radiator in your '41 PU.

Sid, I'd strongly suggest you source a Ford radiator and have it rebuilt. Drake's? Not me, not even at half the asking price.

I bought a Drake radiator for my very original 40 but it simply will not cool on a hot day. Almost pegs the temp gauge after a ten mile drive. I even built another engine because I was beginning to think that maybe the block had a crack somewhere putting exhaust gases into the water jacket. New engine did the same thing. I removed the radiator from one of my other 40s and no more heating issues. Drake could care less that I spent that kind of money on that junk. After a couple calls and promises that we’ll call you back that never happened I decided to take it to the radiator shop and he removed the top tank but found no blockage anywhere.

It’s funny that they aren’t aware of any cooling issues. I made several calls to them explaining my situation and they always said “ we’ll need to call you back”. That never happened.
