This hour, Ron opens with a shop story that starts small and snowballs fast—one chewed vacuum hose on his ’72 Monte Carlo turns into a full dash teardown, heater core drama, brittle plastic parts, and the reality of sourcing quality components for classic cars.

Then it’s on to calls and straight talk: a 2025 Ford Maverick owner worried about oil consumption and a dealer that won’t document concerns, plus a Toyota Corolla owner questioning “universal” synthetic transmission fluid versus manufacturer-spec Type T-IV. Ron explains why documentation matters, how oil consumption can become a long-term emissions/catalyst problem, and why “one fluid fits all” can be a risky gamble.

Also: a listener asks about smartphone alignment tools, and Ron gives a reality check on why phones can’t replace professional alignment equipment—especially on modern vehicles with ADAS.

Cold weather exposes weak links in today’s vehicles, and this hour of Ron Ananian, The Car Doctor breaks them down. Ron explains why modern car batteries should be replaced every 4–5 years—even if they still test good—and why where you buy a battery matters as much as the warranty.

He also dives into start-stop systems and CVT transmissions, explaining how they work, why oil and fluid maintenance is more critical than ever, and what drivers should realistically expect for longevity.

Plus, real-world winter diagnostics, including a no-heat-at-idle problem, air-bound cooling systems, and how to diagnose issues step-by-step without guessing. Practical advice, shop-floor experience, and straight talk for anyone keeping a car past the warranty.
