Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about preventative maintenance and warning signs to keep in mind during the hot summer months. Also on this show:

• Identifying certain smells coming from your vehicle.
• Ways to prevent your car from overheating.
• Is your car safe to drive if it’s leaking coolant?
• Small repairs you shouldn’t avoid in order to prevent a larger repair bill.
• Ways you can tell your car may be overheating without relying solely on the gauge.
• 2009 Mitsubishi Eclipse: After replacing an air flow sensor, my car’s check engine is still coming on. What should I try next?
• 2004 Isuzu Rodeo: My check engine light has been coming on, but goes away each time I take my car to a shop. What should I do?
• 2008 Chevrolet Colorado: I’ve recently replaced the thermostat in this truck. Now that the temperature has gone up, the needle is halfway to hot, but never overheats. Is this something I should be concerned about?
• 2012 GMC Acadia: We’re preparing for a two week road trip, but I’ve noticed a surge in acceleration during the hotter months in stop and go traffic. Have you seen anything like this before?
• A dealership recently charged me $800 for my 40k mile service. I called the dealership I originally purchased the vehicle from and was quoted only $400 for the same services. Is it common to have the same service price vary between dealership?

Cars talked about on this show are the 2009 Mitsubishi Eclipse, 2004 Isuzu Rodeo, 2008 Chevrolet Colorado, and the 2012 GMC Acadia.
