Charge Air Coolers

The charge air cooler, also known as a pre-cooler and/or after-cooler plays a vital part in your truck’s performance and fuel efficiency. Currently there are several standards used by the original equipment manufacturers that allow for imperfect or defective charge air coolers to be installed on your trucks. We have come to know this as the “Acceptable Leak Down Standard”. Such standards adversely affect your truck’s fuel mileage and performance by the constant loss of boost. Electronically controlled engines will attempt to adjust the fuel/air mixtures to compensate for this problem but the outcome is still lower fuel mileage and the loss of power.

Caterpiller 5 PSI over 15 seconds @ 30 PSI
Detroit Diesel 5 PSI over 15 seconds @ 25 PSI
Cummins 7 PSI over 15 seconds @ 30 PSI
Mack 5 PSI over 15 seconds @ 30 PSI

It is believed that this standard was implemented due to the failure rates from the manufacturers of these charge air coolers. As long as their products do not exceed these specifications, it is believed to be acceptable.

We understand your need to harness every once of power, efficiency and fuel economy from your truck. It is for this reason we have set our own standard for all new, remanufactured and repaired charged air coolers. Our acceptable standards for any and all units is 0 PSI over 45 seconds @ 35 PSI.

We set for ourselves this standard as a way to guarantee our customer a reliable and cost effective product. Each and every charge air cooler that leaves our facility, whether is it a repaired unit or a complete new unit will be tested to this standard that we set for ourselves giving you the satisfaction of a much greater potential for increased fuel economy, power, and efficiency from your truck.
