On this episode of  Ron Ananian, The Car Doctor from July of 2015, there are a variety of car issues from callers seeking help.

1. Head Gasket or Cooling System Issue?
   A caller from Omaha, Nebraska, Scott, discusses a potential head gasket issue on his 2024 Ford. Initially concerned about black coolant and overheating, Scott ruled out a head gasket problem after further checks. Ron suggests checking the radiator cap, as a faulty cap can cause coolant to boil over by not maintaining the right pressure, which lowers the boiling point. He advises replacing the radiator after 140,000 miles due to possible inefficiency, especially in older vehicles.

2. Intermittent Engine Problem
   Dennis from Clermont, Florida, reports an occasional engine bucking problem with his 1997 Dodge Van. A mechanic suspects a crankcase sensor issue, though no fault codes have appeared. Ron recommends diagnosing further, especially checking if the check engine light works and scanning for any codes. He stresses the importance of troubleshooting using basic diagnostics and getting fault codes from the mechanic.

3. Fuel Leak Smell in 2002 Concord
   Don from Shelton, Connecticut, calls in about a fuel smell coming from his 2002 Concord. Ron notes the importance of inspecting the fuel system, especially since the vehicle is older, and recommends checking for fuel leaks or damp spots under the vehicle. He warns against driving it if a leak is found, as it could be hazardous.

Throughout the show, Ron provides practical advice, urging listeners to check various car components like pressure caps, sensors, and fuel systems for potential issues that could lead to bigger problems down the road.
