Heavy-Duty Transmission Oil Cooler WAF316195-Replaces OE Part #: F31-6195, F316195

Measuring 45 in long by 12 in wide, this cooler is sized for direct replacement on Peterbilt 320 and 520 chassis, restoring transmission fluid heat rejection without fabrication. These trucks run sustained low-speed, high-load vocational duty cycles — refuse collection and urban stop-and-go routes — where transmission temperatures climb fastest and cooler condition is critical to gear oil life. Cataloged in World American’s HD manual transmission cooling line.
