21504562 is a Mack intercooler core for 2009 Mack CHN models. It measures 12 in. x 12 in. x 12 in., is sold individually, and appears in our parts manual as a chassis mounting intercooler core in the cooling system parts and diagrams. The core cools the hot compressed air coming from the turbocharger before it reaches the intake, which makes the charge denser. A leaking or restricted cooler tends to show up as lost power on grades, poorer fuel economy and a hiss or whistle under load, and left in service a leak makes the turbocharger work harder to make up the difference. Sold by Pro Gear and Transmission.
