CHARGE AIR COOLERS
WHY CHARGE AIR COOLERS?
Charge air coolers are used to cool engine air after it passes through a turbocharger and before it enters the engine. This returns the air to a lower temperature for optimum power in the combustion process. CACs are most often misdiagnosed, undiagnosed and neglected. Often injectors and turbos are replaced when the CAC is the real problem. A leaking charge air cooler impacts the entire engine and can cause:
• Turbocharger failure • Premature injector piston, ring and valve failure • Increased particulate levels in emissions
• Exhaust manifold failure • Increased fuel consumption • Premature DPF failure
Cooled pressurized air from Charge Air Cooler to Engine, temperature out: ±150°F
