Dura-Lite^™ estimates 40% of trucks 2 years or older have charge air coolers that are leaking outside of the engine manufacturers specifications.

A leaking charge air cooler (CAC) is one of the most common causes of reduced diesel truck performance. The problem is that the signs of a leaking CAC are not obvious to the operator or even to the maintenance technician, until the leak is so bad that an increased fuel consumption is noticed.

What happens to the performance of a modern turbo diesel truck engine when the charge air cooler begins to leak?

Unlike a radiator that uses liquid antifreeze (coolant) to cool the engine and will leave a puddle on the ground when it leaks, a CAC leak can only be detected if the CAC is pressure tested to find the air leak.

If you suspect your CAC is leaking, the only way to accurately confirm a leak is to do a pressure test. Testing is quick and easy and usually takes about 20 minutes using a Dura-Lite Tester-Kit^™.

The Dura-Lite Charge Air Cooler Tester-Kit comes complete with everything required to test most charge air coolers.
