AERO-Classics Oil Coolers
FAA-PMA approved and now available at Aircraft Accessories of Oklahoma
AERO-Classics oil coolers are a direct replacement for Stewart-Warner (Meggitt) oil coolers and HE Series high-efficiency coolers. With a precision-designed internal oil flow and durability built-in, they offer equal or better performance than original oil coolers at an affordable price point.
Aircraft Accessories of Oklahoma is proud to be a new authorized distributor of AERO-Classics oil coolers, so you can be confident you’re getting the FAA-PMA approved parts you need to get back in the air sooner. All oil coolers come with 8130-3 documentation, and you can check current stock, availability, price, and options with just one call.
Why aircraft owners and operators choose AERO-Classics Oil Coolers
Oil cooler performance comes down to four factors: Heat rejection, pressure drop, air-side restriction, and durability.
In side-by-side comparative testing, AERO-Classic’s 7- and 9-plate oil coolers outclassed competitive models, offering better overall cooling and lower pressure drop. Plus, AERO-Classic’s in-house testing shows that their high-efficiency cooler with a greater fin area rejects heat faster than standard oil coolers.
AERO-Classics oil coolers are also corrosion-protected (per MIL-C-5541, Class 1A), pressure-tested to 400 psig, and come with a two-year warranty.
AERO-Classics Oil Coolers come in three mounting variations
Rear-mount
These oil coolers bolt directly to the engine and don’t require hoses. Many Continental engines use this type of oil cooler installation, though there are several bolt configurations and variations within this mounting type.
Front-mount
Like rear-mount oil coolers, front-mount oil coolers bolt directly to the engine and don’t require hoses. Many Continental engines use this type of oil cooler.
Remote-mount
This type of oil cooler mounts to the airframe or engine baffle and is connected to the engine by hoses. Most non-Continental engines and all Lycoming engines use this type of oil cooler.
Directly replace Stewart-Warner Oil Coolers with higher efficiency and performance
Stewart-Warner (Meggitt) oil coolers have long been the legacy standard oil cooler found on many certified and experimental aircraft. But AERO-Classics oil coolers offer similar or higher efficiency, better affordability, greater availability, and a lighter weight—all with FAA-PMA approval.
Note: Some aviation suppliers sell Stewart-Warner oil coolers as ‘fit’ replacements, but they’re not furnished with FAA-PMA approval for that application—even if they have the same part number and manufacturer as approved parts. AERO-Classics oil coolers are a bolt-in replacement with FAA-PMA approval and 8130-3 documentation, making installs simple.
