On this episode of Classic Car Doctor podcast from July 18, 2015, Ron Ananian  discusses various car repair topics, answering listener questions:

1. Clifford’s 2003 Toyota Camry Issues:

   • Clifford has an exhaust leak likely caused by a flex pipe. Ron explains that repairing it requires welding and possibly replacing the catalytic converter, depending on the model. While replacing just the flex coupling may be an option, replacing the entire exhaust system could be more cost-effective long-term. Additionally, Clifford reports burning oil, and Ron suspects it’s due to worn valve seals, which is common for a car of this age. He advises staying with the recommended 5W-30 oil but suggests considering a valve seal replacement to manage oil consumption.

2. Charles’ Battery Acid Shelf Life:

   • Charles asks about the shelf life of battery acid, which can degrade over time. Ron explains that battery acid typically lasts 3-5 years and advises buying fresh acid to restore the battery. He also explains how older acid may cause performance issues and recommends checking the battery and acid for any deterioration.

3. Scott’s Jeep Cherokee Swap:

   • Scott wants to swap parts from a 1999 Jeep Cherokee into a 1997 model, including the engine and drivetrain. Ron advises checking the Vehicle Identification Numbers (VINs) and using an interchange guide to determine compatibility of parts. While the engines are similar, Ron cautions about potential differences in components like oil pans, sensors, and flywheels, and suggests some tweaking might be necessary for the swap.

4. Austin’s 1998 Mercury Grand Marquis Electrical Problem:

   • Austin faces intermittent electrical issues with his car, which dies unexpectedly despite a new alternator. Ron suspects a battery drain issue and suggests checking fuses, the lighting control module (which may have been recalled), or a potential fault with the keyless entry system. He advises performing a detailed diagnostic test to identify the exact cause of the drain before replacing more parts.

In this episode of Ron Ananian, The Car Doctor, Ron shares a story about a longtime customer, Larry, who recently decided to purchase a classic car. Initially, Larry was interested in a 1963 Corvette, but he ended up buying a 1967 Volkswagen Beetle instead. Although Ron was initially skeptical about Larry's choice, Larry was drawn to the Beetle after seeing its restoration. The car had some issues when it came to the shop, including needing an oil change and a broken horn.

Ron explains how fixing the horn was trickier than expected due to the car's outdated wiring system. He shares how the horn system works with just two wires and how the problem was ultimately traced back to loose spade terminals that needed cleaning and tightening. The simplicity of older cars is highlighted when Ron compares the Beetle’s two-page wiring diagram to the complexity of modern vehicles. Ron reflects on the nostalgia and joy that old cars like Larry’s bring, emphasizing how classic cars are more than just transportation—they hold sentimental value and remind people of simpler times.

Later in the show, Ron offers advice on a brake issue for a listener with a 2011 Ford Edge. Despite replacing the master cylinder and rear calipers, the listener still had a spongy brake pedal. Ron suggests that the issue might be with the ABS control unit, which often gets overlooked. He advises performing an ABS bleed and, if necessary, replacing the ABS unit. Ron concludes by discussing the importance of regular brake fluid maintenance to avoid similar problems in the future.

Lastly, Ron answers an email from a listener named Dave, whose friend is concerned about a coolant service being recommended by a Toyota dealer for a 2023 Toyota Highlander Hybrid. Ron clarifies that the coolant in the inverter cooling system is likely the same Toyota Super Long Life coolant used in the rest of the cooling system, and suggests waiting until the car reaches around 60,000 miles for this service.

In summary, the episode covers stories about classic car repairs, advice on brake maintenance, and clarification on coolant servicing for hybrid vehicles. Ron emphasizes the importance of regular maintenance and how older cars continue to evoke strong memories.
