MACS Show: Technical Session Coverage
Once a year, the Mobile Air Conditioning Society (MACS) hosts a trade show for A/C shop owners and technicians. This year’s event in Orlando, FL, provided a wealth of service information to those who attended the technical sessions. For those who couldn’t be there, we pass along some of the highlights from the technical sessions.
Chrysler Neon 2.0L
When Chrysler introduced their new Neon models back in 1995 under the Dodge and Plymouth nameplates, they said they were launching a new generation of “fun-to-drive” entry-level cars that would appeal to a wide range of people. Everything was new about the Neon: a brand new body, a brand new chassis and two new engines,
Nissan Brake/ABS Service Essentials
If you’re an import specialist technician reading this magazine, you’re very familiar with brake repair and service. Although the nuts and bolts have changed little over the years, it’s never a bad idea to look at even the most routine job, since ABS has certainly redefined the problems we encounter as well as the changed
Selling Multi-Coil Ignition Parts
Time has indeed passed you by if you still believe in the traditional import engine tuneup. Many years ago, much of the import service market revolved around the annual spark plug, ignition cable, distributor cap and rotor replacement needed to maintain an import engine at peak efficiency. During the past decade, however, multi-coil waste-spark and
OBD II Diagnostics:Tips And Tricks to Make the Process Easier
The Malfunction Indicator Lamp (MIL) can be a golden light of opportunity for your shop. If the light comes on, it means the Onboard Diagnostics II system (OBD II) has detected an emissions-related problem. OBD II is designed to turn on the MIL if a problem occurs that may cause emissions to exceed federal limits
Diagnosing and Fixing Compressor Failures
The compressor is the heart of the refrigeration circuit. It pumps and pressurizes the refrigerant to move it through the A/C system. Compressors work hard and run hot, up to several hundred degrees and several hundred pounds per square inch of internal pressure, yet they rely on only a few ounces of lubricant to keep
Mass Air Flow Operation Strategy
When diagnosing hot-wire air flow meters (A/F meters) on Subarus and similarly equipped Asian vehicles, technicians may find that, while the meter passes all recommended test procedures, the engine exhibits driveability conditions associated with lean air/fuel mixture ratios. In these cases, it’s best to form a diagnostic strategy based on the relatively simple operating principles
Muscling in on Restoration & Performance Work: Part 1
As automotive technology continues to become more complex with each new model year, you may be longing for the “good ol’ days” when engines had carburetors and distributors but no sensors, fuel injectors or computers. Most driveability problems were fairly simple to diagnose and only required a trained ear and a few basic tools. Alas,
Understanding Operating Strategies
As driveability technicians, we’ve been taught to solve diagnostic problems by gathering and analyzing data. Data usually comes in three basic forms, the first of which is sensory data that we can see, hear, smell or feel. The second form is measured values gathered by using test equipment like lab scopes and multimeters. The third
Your Business is a ‘People’ Business
