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 talks about car leaks, air conditioning, and what flashing check engine lights mean.

Also on this show:

• Leaks are not always found on your garage floor.
• If your power steering fluid gets low, it must be a leak because your car does not consume it like oil.
• 2000 GMC Yukon. Trouble codes showing knock sensor problem. Replaced them and code comes back.
• Ford 5150. Temperature gauge spiked up and low oil gauge came on. Oil and coolent were empty.
• 2000 Chevrolet Impala. Radiator leak. Can I order a part and have a shop install it?
• Low price shops are not always a better deal. How paying more for a repair can get you more.
• 2008 Dodge Challenger. Air conditioning won't go in recycle mode.
• 2006 Mustang GT with 60,000 mile. Sound coming out of the rear in sync with tire rotation.
• Is putting break fluid in your transmission a good idea to stop a leak?
• 2001 Saturn. Sputtering and stalling while driving. Check engine light is flashing.
• 2005 Ford Freestyle. Replace front and rear air conditioning compressors, but front blowers are still not working.
• 2001 Dodge Truck. Air conditioner only blows cold air when in neutral.
