Ron Ananian, The Car Doctor, opens the hour with Cherokee Heart from Mahwah Ford, discussing how tariffs are beginning to impact car prices—particularly for the Mach-E, Maverick, and Bronco Sport. While Ford is absorbing some of the cost increases, buyers may still see higher prices. Financing remains accessible even for those with fair credit, and although leasing has become more expensive, Ford is offering attractive incentives. Cherokee advises acting now before tariff-affected inventory hits the lots.

In the second half, Ron speaks with Isaac Nielsen of MAHLE Aftermarket about the industry’s shift to R-1234yf refrigerant, now standard in most vehicles since 2013. Unlike older A/C systems, modern machines include refrigerant identifiers and oxygen sensors to ensure at least 98% purity. DIY recharge kits can pose risks due to impure blends or excessive dye and oil. Isaac stresses the need for regular maintenance, including filter checks, hose flushing, and line cleaning. Oxygen sensors naturally degrade with air exposure and must be stored correctly. Neglecting care can result in costly equipment damage.

Ron Ananian, The Car Doctor shares a story about a first-time customer who brought in a 2008 Volvo with a salvage title. Shop policy required a full inspection, which the customer agreed to, but his wife was upset about the cost and disclosure. Ron stresses the importance of honesty, comparing it to telling a doctor your full medical history. The inspection revealed past rear damage, but the car was safe if properly maintained.

Later, a caller named Jim sought advice on fixing a persistent oil leak in his Cadillac Escalade. Ron suggested checking for a warped housing and cautioned against sealant on the face of the shim gasket

Another caller, Mike, recommended using a stylus for touchscreens in cold weather, which Ron agreed was practical but noted that some issues are mechanical, not just usability-related. Overall, the episode highlighted the value of transparency and careful diagnostics in car repair.
