This is the stand alone interview from the June 7, 2025 Hour 1 Show.

Ron Ananian ("The Car Doctor") and Isaac Nielsen of Mahle Aftermarket discuss modern automotive A/C systems, focusing on R-1234yf refrigerant and the importance of proper service equipment.


R-1234yf replaced R-134a and requires stricter handling due to contamination risks.


All A/C machines now include oxygen sensors and refrigerant identifiers to ensure refrigerant purity (≥98%) and prevent system damage.


DIY charge kits and low-quality refrigerants (especially imports) can harm vehicles and equipment.


Maintenance tips: Check filters for discoloration, clean internal lines with isopropyl alcohol, and flush hoses weekly.


Oxygen sensors degrade over time, even in storage—only buy replacements when needed, as early shelf life affects performance.

🔧 Bottom line: Use quality refrigerant, maintain your machine, and monitor sensors to avoid costly failures.

It’s the last live show of the year on Ron Ananian, The Car Doctor—and Ron explains what’s coming next: a Best-Of show next weekend, then back live New Year’s weekend. Ron also reminds listeners the broadcast becomes a podcast (search Ron Ananian, The Car Doctor on iHeart, Apple, Amazon, Google, and more).

Plus, a caller with a 2023 Ford F-150 faces a persistent check engine light tied to a catalytic converter concern—Ron walks through why this should fall under federal emissions warranty coverage, why the dealer’s diagnostic fee may not ultimately come out of the caller’s pocket, and what to do to get the repair properly documented.

Then the show rolls on with used-car shopping advice, EVAP and purge-valve talk, and a holiday closer you’ve got to hear.

Ron Ananian, The Car Doctor - December 20, 2025 - Hour 2 - The Night Before Christmas  (855)560-9900

Ron Ananian, The Car Doctor opens with a Christmas-season story that stops him cold at a red light in Ramsey, NJ—when he realizes a young couple in the car next to him is listening to his show on the podcast. From there, Ron dives into the real-world chaos of modern repairs: a 2012 Mazda 3 owner spends $1,800 at a dealership with no clear diagnostic paperwork… only to be told the next step is an “obsolete” engine computer. Ron explains why probability, parts availability, and honest research matter before taking a customer down an expensive road. Plus, calls on a Chrysler 300C oil pressure sensor code, Honda CVT fluid service intervals (and the confusion around filters and fluid types), and a hard-start condition that may point to fuel delivery or pressure-regulator issues.

Do You Really Need to Warm Up Your Car?

On this episode of Mendte in the Morning on WOR Radio 710, Ron Ananian, The Car Doctor, clears up one of winter’s most debated questions—should you warm up your car before driving?

Ron explains what modern vehicles really need, why safety and visibility matter more than internet myths, and when a short warm-up actually makes sense—especially in cold Northeast mornings. Plus, why using hot water on an icy windshield is a very bad idea, how idling laws factor in, and what older vehicles still demand in freezing temps.

The conversation wraps up with advice on buying a car as a gift—why the big bow looks great in commercials, but real-world car buying should be an experience, not a surprise.
