Air leaks can be a major frustration for drivers and mechanics, causing delays and unnecessary wear on your truck’s air system. In this video, Team Run Smart Pro Bob Caffee walks through how to identify air leaks, whether they’re audible or hidden, the best way to use a soap solution to detect leaks, and simple fixes for common air fitting leaks.

💡A quick tip: If you spot a leak, trimming 1/4 inch off the airline before reinserting it can sometimes fix the issue without needing to replace the fitting.
