Ron Ananian, The Car Doctor - July 18, 2026
A simple check engine light on a high-mileage 2016 Chevy Silverado Duramax turns into a lesson in why experience matters. Ron shares the tense, hour-long battle to safely remove a seized glow plug without turning an $800 repair into an $18,000 engine replacement—and explains why the best technicians know when to slow down.
Also this week, Ron talks with a Honda owner wondering if a dealership's $3,300 repair recommendation is really necessary, helps diagnose a no-crank Cadillac CTS, discusses Harley-Davidson starting issues, and explains why sometimes the most valuable tool in the shop isn't a scan tool or a socket set—it's decades of experience.
It's another hour of Car Advice, Done Right.
