Ron Ananian, The Car Doctor - March 29, 2025 Hour 1 - Why Does A 4 Cylinder Engine Have 8 Spark Plugs? (855)560-9900 24/7 Hotline

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 Ron explains how fixing the horn was trickier than expected due to the car's outdated wiring system.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.
