1930-31 Model AA Commercial Truck Radiator w/ Flat Tube Core Price $725.00 Prev Next Product Description Similar to the Model A car and car based pick-up radiators in design, the commercial Model AA truck radiators of March 1930 - 1931 have a thicker core. The radiator's neck and the thicker core necessitated advancing the radiator forward in the shell. The car radiators and car-based pick up radiator will not fit the shell brackets and neck location in the commercial shell. Placing a AA Commercial Truck radiator in a car or car based pick-up will interfere with the fan. Features of the 1930 and 1931 Model AA Truck Radiator with Flat Tube Modern Efficent Core include: Tellurium copper core design with 10 fins per inch fin density Louvers embossed between each fin to disrupt air flow and facilitate heat transfer 3/4" seamless weld tubes in a staggered array to disrupt airflow laterally Deep drawn one piece brass die stamped top tank with correct die stampings Galvanized steel sidewalls to resist rust Cast cowl rod bracket for support rods to firewall (re-designed Fall 2015) Internal baffle in top tank to prevent coolant loss Correct angle on top hose inlet Correct depth bottom tank to clear crank Electric wire tabs soldered to lower tank Hood mount tabs Clean solder lines - not gobbed on Painted flat black to aid in heat exchange Our 1930 and 1931 Model A and Model AA Commercial truck reproductions are aftermarket products. The design is based upon original drawings provided by Ford and original radiators we have collected over the last 25 years. Each radiator is tested with an original Ford shell to assure general fit, appropriate neck placement and accurate mounting bracket placement. If for any reason you are not satisfied with the fit, finish, design or craftmanship the radiator may be returned to us postage pre-paid in new and re-saleable condition for a refund. A note about "fit" Commercial trucks have a deeper shell than car-based pickups which will impacts neck location and core thickness. Our necks are made to fit with original caps. Necks have a tang to guide on the cap and stop it at the lock position. It is likely to be steeper and tighter than the 80-90 years old necks found on an original radiator. Quails and motometers have always been an aftermarket product. Today they are made in Taiwan or China and they may not fit our neck. Some customers have reported that they die grind the cap's casting with a dremmel or file to guide the tab as it climbs the neck tang. Not all waterpipes are the same which may affect the rubber hose connection. Please review the photo illustrating lower hose connections, contact us if you have an incorrect lower hose connection for your production year.
