ACP OE-Style Type 259 Performance Aluminum 2-Row MaxCore Radiator for 1965-1966 V8 Mustangs.

Looking to replace the radiator in your classic 1965-1966 V8 Mustang for something that can keep it running cool a bit more efficiently? Then take a look at this ACP OE-Style Type 259 Performance Aluminum 2-Row MaxCore Radiator from CJ Pony Parts! This radiator is similar in size and design as the original radiator in your V8 Mustang, but the aluminum design allows it to cool your Mustangs engine more effectively.

ACP MaxCore Radiator FM-ER201 Features:
- Direct Fit OE Style
- Aluminum Construction
- Billet Filler Neck
- Integrated Transmission cooler for Automatic Transmissions
- OEM Style Brass Petcock for Easy Draining
- 2-Rows of 1-1/4” Tubes

This radiator was designed to be a direct fit OE style radiator that will mount into your Mustang using the factory mounting points without any fabrication or extra drilling needed. Aluminum construction and two rows of 1-1/4” tubes aids in better heat dissipation so that your classic Mustang can stay running nice and cool on the hottest of days. The top and bottom tanks are styled like the original tanks and feature an OEM style brass petcock that allows for easy draining of the coolant. This radiator also features an integrated transmission cooler for Mustangs with an automatic transmission.

The idea of creating a radiator from aluminum was based on using more tubes that were wider and lowering the height of the fins. This would eliminate dead space between the tubes. The standard aluminum radiator tube width is 1”, so a typical 2-row aluminum radiator has a 2” tube-to-fin contact area per row.  Compared to the typical 4-row copper radiators which had a 1.7” tube-to-fin contact area. So ACP decided to kick it up a notch by making the tubes in their 2-row MaxCore radiator 1-1/4” wide creating a 2-1/2” tube-to-fin contact area. Greatly exceeding the performance of a copper 4-row design.
