Dura-Lite® Tester Kit and Testing Procedures
The Dura-Lite® Charge Air Cooler Test Kit was designed to aid you in knowing what tests you should run every time a truck is in for servicing. These tests should be as automatic as checking the oil and will give you confidence in knowing that a truck is performing at the performance levels required.
