Ford never made a pressurized Model A radiator but our customers frequently request it. Sometimes they have overdrives, high compression heads, down draft carburetors or other modifications or they just drive faster than the average top speed of a Model A in its production year e.g. about 35mph.
Why use a pressurized system? Water at sea level boils at 223 degress Farenheit and for every pound of pressure, you raise the boiling point of water by 3 degrees. With our recommended 4psi cap and with a 50/50 mix of ethylene glycol it will boil at 235 degrees. Its unlikely that a Model A engine would ever see these temperatures but it is not uncommon for drivers to lose fluid at higher rpms. Even with the internal baffle fluid will find a way out and fluid levels become one more thing to manage on your Model A.
Using an elbow and keeping the neck and cap below the hood line your original Model A will look authentic from the outside and keep the engine cool inside. Whether in a slow moving parade, creeping up a long uphill grade or touring at higher speeds or racing in the regional hill climb or local time trial a pressurized system will provide you with peace of mind.
Features of the Pressurized 1928 and 1929 Model A radiators include:
- Modern efficient copper core design with 10 fins per inch
- 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
- Die stamped three piece brass top tanks with model correct die stampings
- Galvanized steel sidewalls to resist rust
- Cowl rod bracket for support rods to firewall
- Internal baffle in top tank to prevent coolant loss
- Correct angle on lower outlet to clear power house generators
- Electric wire tabs soldered to lower tank
- Hood mount tabs soldered to top tank
- Painted flat black to aid in heat exchange
- Radiator image seen with a fan shroud, fan, quail and overflow tank is available as separate items.
Our 1928 and 1929 Model A and Model AA truck reproductions are aftermarket products. The design is based upon original drawings provided by Ford and original radiators we have collected over the last 35 years. Each radiator is tested with an original Ford shell to assure general fit, appropriate neck placement and accurate mounting bracket placement. Each 1928-1929 radiator is also tested with an original fan shroud to assure fit. 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.
