About this episode

Ron Ananian discusses the challenges of removing a seized glow plug and shares automotive advice on various vehicle issues.

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. 🌐Visit: CarDoctorShow.com 📸 Follow Ron on Instagram: @ronananian 🎥 Watch repair tips and shop videos on YouTube 📻 Join the conversation LIVE Saturdays 2–4 PM Eastern   See omnystudio.com/listener for privacy information.
