Fifteen years ago, I bought my first home. Like most buyers, I relied on the professional home inspection, which included a radon test. It was summer, and the results came back at 2 pCi/L—well under the EPA action limit. I was told the house was safe, and for most people, that would have been the end of the story.
I decided to write this guide for two reasons. First, the level of misunderstanding regarding electrical safety is massive. This isn’t necessarily your fault; the word grounding itself is a historical misnomer. Most people misunderstand it, and surprisingly, many licensed electricians do too. Second, grounding is vital—do it right, and it saves lives; get it wrong, and it can kill.

In 2024, I decided to give my 2006 Volvo XC90 (currently pushing 262k miles!) a much-needed audio system upgrade. My goal was to install a modern Android head unit to gain features like Android Auto, Apple CarPlay, and dedicated inputs for a backup camera and dashcam.
This is a guide on fixing the notorious weak heating issue on the Volvo XC90/S8 V8 engine. I’ll walk you through the troubleshooting journey first, but if you’re just here for the solution, feel free to scroll down to "The Actual Fix"—but you will miss the context on why these pumps fail!
