More from Ron Ananian The Car Doctor

Ron Ananian, The Car Doctor - Classic Car Doctor - October 10, 2015 - Hour 2 - You Love Your Car More Than You ThinkFrom the Car Doctor archives — originally aired October 2015. In this classic episode of Ron Ananian, The Car Doctor, Ron opens the hour with a thoughtful discussion about the emotional connection we develop with our vehicles—often without realizing just how attached we've become. Whether it's the family car that's been through years of memories or the vehicle that always seems to get us home, cars become more than machines. Ron then helps a caller diagnose cooling system problems on a 2007 Mercury Mountaineer and takes a call from a 2013 Toyota Highlander owner whose wheels were nearly left loose after a routine oil change, leading to an important conversation about trust, quality workmanship, and paying attention after service. Also featured is an interview with Derek Miller from ALLDATA, discussing vehicle repair information, diagnostic resources, and the growing complexity of modern automobiles. Ron rounds out the hour by answering listener emails about choosing the right OBD-II scan tool and diagnosing hesitation and rough idle concerns on a Toyota. A great mix of automotive advice, consumer awareness, and a reminder that our relationship with our cars is often more personal than we think.
