Heavy Duty Charge Air Coolers

Although charge air coolers (cac’s) are now being used in high performance cars such as BMW’s and Audis, they have been used in over-the-road heavy-duty trucks since the 1970’s.

Considering that temperatures in an in-service cac reach 500 F and the harsh impaction and vibration which they endure, it’s no wonder they need servicing, re-coring or replacement. The most common problems with cac’s are cracks in the tubes or in the tube/header joints. As the truck moves over the road the cracks get bigger and pressure and performance are lost and fuel efficiency decreases. Heavy duty truck operators should have their cac’s regularly tested and inspected.

Problems with heavy duty truck cac’s can be addressed by repair, re-coring or replacement with a new unit.
