1928-1929 Radiator

1928 and 1929 Ford Model A Radiators

We make aftermarket radiators from Ford blueprints and originals we have collected. We do our best and want you to be satisfied with your radiator purchase but Ford did not make things easy on us.  Please read the section below about 1928-1929 Fords to help you understand why you may have a fit issue.

If you have any concerns about fit after reading this then send us your original radiator and we will build from your dimensions a radiator that fits your specific car.  We do this every day for Concours cars.  You will spend about 35-55 dollars in freight but buy piece of mind.

If you however trust us to build your radiator to Ford’s dimensions and want us to sell you an aftermarket radiator then order and inspect it upon receipt. If you are not satisfied for any reason, contact us to arrange a return for your money back or return it freight prepaid.  We only request that the radiator is in new and resalable condition e.g. clean of fluid and not damaged.

A few notes about “fit”


Henry Ford was a clever businessman and constructed a popular product in the Model A.  When his business took off, design changes were frequent.

Ford produced 1928 radiators in the Highland Park and then switched to the Green Island Plant in early 1929. Continued success required contracting with alternative manufacturers at the Long, Flintlock and McCord plants in mid 1929. Model A owners may be surprised to learn that there was specification “drift” in these factories to meet the sales demands in 1929.

Inlet Height: Ford made a series of frame changes in each production year and introduced longer bolts and shims which raise the radiator. While shim thickness was never detailed in the Ford releases, the recommended bolts lengthen by as much as 1/4″. Shims may be required to raise your radiator and frame to align the inlet and water neck.

Lower hose angle: Ford angled the lower hose connection toward the ground and tire to clear the power house generator. Fewer drivers today use the generator but the correct angle is necessary to align the water pipe. We angle lower hose connections as Ford did.



Lower hose length: To many a water pipe is a water pipe but not all water pipe connections are the same. The slight differences in the illustration may seem inconsequential but this may affect the angle of the rubber hose.

The front cross member on frames beginning late ’29 has shallower radiator mounting pads. When used with ’29 type bodies, Ford compensated for this with longer mounting bolts and steel shims, along with the usual rubber pads. Unfortunately, most owners do not know the year of their frame and Ford did not provide the dimensions of the shims. This could impact the upper inlet angle and height and potentially impact the visibility of the header in the shell’s core opening.

Compounding all of these issues, your Model A may have aftermarket products that are out-of-tolerance, have a mixing-and-matching of parts from different years or have frame twist or frame spread.

Any or all of these factors may result in a “fit” issue.

Headlight Conduit Identification




A - 1928-early '29 headlamp conduit made from brass. These were used with all Ford "H" headlamps. I believe this is an original which was chrome plated during a "restoration" 40-50 years ago.

B & C - These are both 1929 headlamp conduits made of brass and nickel plated. These were used with 1929 type Twolite Headlamps. I suspect one of the two was Ford's design and the other an alternate design from an outside supplier. If there were usage dates specified by Ford for either or both is unknown at this time.

D - The common rustless steel headlamp conduit used throughout 1930-31 on passenger cars and Deluxe commercial models.

E - 1930-31 rustless steel horn conduit. All horn conduits followed this pattern but were mad of nickel plated brass in 1928-29.

F - 1930-31 non-metallic conduit (composite image). These were used on standard "A" and "AA" commercial models which had black enameled headlamp cases. These were designed for use with the new 1930 style commercial bodies which were introduced in late June 1930. They MAY not have appeared in production until August 1930.

RANDOM FINDINGS:
- The extended length of the headlamp conduits varied all years. I have a fairly large sampling and all types ranged from 7" to a little over 8". The majority fall between 7-1/4" and 7-3/4" long. As an example of variation, I have a pair of each of the '29 type conduits shown which came on a single vehicle in each case. The length from one side to the other differed by approximately 1/2". The longer of the two has just over two additional spiral wraps

- I don't have a suitable sampling of horn conduits to provide a range on the lengths.

- The outside diameter measures .485"-.490" on the 1928 type headlamp conduits and all horn conduits. The larger Twolite headlamp conduits average .545".

- Of approximately 20 samples of the "rustless steel" conduits, all are magnetic stainless except for one lamp conduit and one horn conduit which are non-magnetic.

- It's important to note that the telltale sign of original conduits the shape of the end bushings on each type. I've never seen any replacements or reproductions that match up although I believe A&L makes the latest type good enough to fool the casual observer.

Finally, the photo below shows a few NOS non-metallic headlamp conduits. Note the difference in the design of the bushing at the headlamp end. I suspect these were made in the mid-late 1930's as service replacements. The few used originals I've seen as well as archive photos that show the conduits all show the design above.
