The Vacuum Gauge

[Dakota]

Hey Eric, I saw the video of the Subaru and using a vacuum gauge to know if there’s an exhaust restriction. You said that the vacuum gauge was the scan tool before scan tools were a thing. Since they’re so useful even today, you should make a video about how they work and how to read them!

Honestly with modern vehicles and scan equipment, it’s virtually obsolete. Talking about engine vacuum as a diagnostic tool is a great idea though. Thanks for the suggestion.

I’m still working on the Fairmont in hopes to get it done soon. Once that project is complete and I have some time to catch my breath, I’ll look into making more videos like this. In the mean time, this will give you some useful information on the use of a vacuum gauge.
