Diagnostic Solutions: Cylinder Head Repair
Cylinder head gasket failures are one of the most common mechanical issues facing today’s modern import technician. One reason head gasket failures are common is because the cylinder head gasket itself can become a wearing part. Since the aluminum cylinder head expands at a slightly higher rate than the cast-iron cylinder block, the cylinder head actually slides a few thousandths of an inch across the gasket surface as the engine warms up to operating temperature.
Diagnostic Solutions: Diagnosing Misfires
Although diagnosing misfires can be a tough assignment for any driveability technician, the diagnosis can be made much simpler if he understands the basics of misfire diagnosis. For example, when the first OBD II misfire monitor was first introduced in 1996, technicians were puzzled by problems with false misfire diagnostic trouble codes (DTCs). Case in point, vehicles being driven on washboard dirt roads began recording false misfires.
Diagnostic Solutions: Conducting Non-Intrusive Cooling System Inspections
Perhaps the best way to begin when we get a cooling system overheating complaint in our service bay is by using a series of quick, non-intrusive cooling system tests that establish the basics without removing major parts.
Tech Tip: Air Tools Save Technicians Time, but Require their Own Maintenance to Ensure they’ll Provide Support
Air tools are profitable timesavers for professional technicians because pneumatic muscle speeds up disassembly and reassembly. That allows most technicians to beat flat rate and get paid for more billable hours. Professional grade air tools can be very expensive and represent a sizable investment. But the tools can last many years with the proper care – and a clean air supply.
Diagnostic Solutions, Servicing Filters: Top-Notch Design Is Key When Selecting New Filters
Veteran auto mechanics well remember the days of oil-bath air filters, cartridge-type oil filters, and sediment-bowl fuel filters. While these early-design filters would work well under a narrow range of circumstances, most were woefully inefficient and inadequate in the long term. All were subject to careless installation and dirt contamination during servicing. As disposable “paper”
Diagnostic Solutions: Reading Spark Plugs Is As Much An Art As It Is A Science
Barring mechanical contact between the spark plug and piston, just about any randomly selected spark plug will ignite the gasoline and air compressed into an engine’s combustion chamber. Very few spark plugs, however, will continue to perform well under a wide range of engine temperatures, loads and speeds, not to mention lasting well beyond today’s
Diagnostic Solutions: Wheel Bearing Diagnosis
PROPER PROCEDURES AND CORRECT TOOLS PREVENT COMEBACKS Although wheel bearings are often the most neglected part of the vehicle, they nevertheless have a critical job to do, and in most cases, do it very well. Not only are wheel bearings designed to support the weight of the vehicle and allow it to travel over a
