MONTHLY TECH TIPS
Tech Tip of the Month: Boost Leaks Cause Big Problems
This month's tip focuses on one of the most common-and most overlooked—issues on
Class 8 trucks: charge-air cooler (CAC) leaks.
Symptom:
Low power, slow acceleration, poor fuel economy - and no fault codes.
The Hidden Issue:
A small crack in a CAC boot or a loose clamp can bleed off boost pressure long before the
ECM detects anything wrong. Even a minor leak can drop usable power by 30-50%.
Quick Diagnostic Steps:
• Perform a smoke test on the charge-air system
• Check boots for hairne cracks, rubbing
- spots, or oil saturation
- Confirm clamps are tight and not bottomed-out
- Pressure test system to manufacturer spec (typically around 30 psi)
Why It Matters:
Boost leaks force the turbo to work harder, increase EGTs, reduce fuel efficiency, and eventually create bigger problems like premature turbo failure.
Pro Tip:
If a truck has low power with no codes, always start with the boost system. It's quick to test and often the root cause.
