significantly reduce diagnsotic time for air leaks (including the intake, exhaust, and aftertreatment systems) leading to regen,
power and/or exhaust odor concerns.

To prevent personal injury or death, read all safety instructions in the "Safety
Information" section of the Engine Diagnostic Manual or Engine Service manual.
IMPORTANT NOTES:
• Due to the size of some engine components (as well as wide temperature ranges encountered during normal operation),
"pinhole" leaks can occur at some sealing surfaces. Generally, pinhole leaks do not result in odors or performance issues-focus on large leaks.
• Do not exceed 5 psi pressure, with the tool. Higher smoke pressures can obscure test results as teh fast-moving smoke
can be difficult to see. At lower pressures, smoke trails "curl" out smoothly and remain visible much longer.
• Smoke from the Leak Locator cannot pass through a properly operating Diesel Particualte Filter (DPF). To properly test
the Aftertreatment System, test areas before and after the DPF, seperately.
• Some components (for example the High Pressure Charge Air Cooler-HPCAC) have slight air leaks, by design. For these
components, it is necessary to perform a leak decay test (outlined in the Diagnostic Manual) to deem the part non
conforming.
DIAGNOSTIC PROCEDURE
The diagnostics are split into three sections; Intake, Exhaust and Aftertreatment, and are hyperlinked accordingly. Perform the necessary diagnostics
relative to the customer/performance concern.
INTAKE TESTING:
1. Remove intake piping
2. Install intake adapter into air intake piping
3. Using air intake piping clamp, tighten clamp around adapter
4. Connect Navistar Leak Locator line to intake adapter
