Diagnostic Solutions: Steering Gears

Keeping Your Customers’ Vehicles on The Straight & Narrow Modern automotive steering gears evolved from the quaint tiller-controlled steering systems used in the first automobiles to the hydraulically controlled systems now used in most import vehicles. Unfortunately, steering tillers that attached to axles with little or no steering geometry didn’t provide much steering feedback from

Pumping Oil

For me, sourcing automotive chemicals and motor oils goes all the way back to 1957 when I worked at my corner service station. Since we were a small town without a local parts jobber, we bought our oil additives and chemicals from an out-of-town distributor. Our gasoline and motor oil came from our local-branded petroleum

Diagnostic Dilemmas: The Misfire Code As a Symptom

Without question, the 1996 and newer OBD II systems have greatly simplified the diagnostic process. Veteran mechanics well remember the technical loopholes that riddled the old proprietary OBD I systems. All too often, the complex diagnostic charts supplied by the auto manufacturers were time-consuming, erroneous and often concluded with the infamous “replace with component of

Power Options: Restoring a Vehicle to Like-New Performance

Replacing a worn or broken engine on a customer’s vehicle can be a very sensitive subject for many independent shop owners because it’s a time-intensive and possibly high-liability service. After a replacement is done, a shop’s greatest fear is that a minor ticking noise or oil leak may ruin the profitability of the engine replacement.

What is your strategy for exhaust service?

Diagnostic Solutions: Oxygen Sensor Diagnostics

Once considered leading-edge technology, today’s oxygen sensor has become a commonplace service item on modern vehicles. Popularly introduced in the 1970s, the Lambda or, as it’s more popularly known, the oxygen sensor, rapidly became standard equipment as it’s a vital component of closed-loop or feedback fuel control technology. By using a voltage input from the

Component Connection: The Circle of (Engine) Life

Amazingly, up to a third of the heat energy produced inside an engine’s combustion chambers ends up as waste heat that goes into the block. This heat must be eliminated, otherwise the engine will overheat and self-destruct. The water pump keeps coolant circulating between the engine and radiator to get rid of the heat. The

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”

Selling Services: Providing Manual Transmission Clutch Replacement Service

Because a good “stick shift” driver can always squeeze a few more miles per gallon out of a manual transmission or otherwise out-perform their automatic transmission counterparts, it’s no wonder that clutch replacements continue to be a good business for repair shops. In most cases, a routine clutch replacement requires very little in special tooling

Diagnostic Dilemmas: The Pressures of Intake Manifold Vacuum Tests

Several years ago, a retired school teacher brought in a 1994 Chevrolet S-10 Blazer that had developed an intermittent rough idle condition. Although a rebuilt engine had been installed a year before, and all of the wiring and vacuum hoses looked as if they were in factory condition, I took nothing for granted. An ignition

Master Cylinder Inspection

Although the mechanics of modern master cylinders seem deceptively simple, today’s dual-piston or tandem master cylinders still require the utmost in care and attention to maintain safe, reliable operation. The tandem master cylinder contains two piston assemblies; one for each axle set or diagonally located pair of brakes. Each piston assembly has two lip seals

Diagnostic Solutions: Throttle Position Sensors

Although conventional throttle position sensors attached to the throttle shaft are considered basic technology on modern engine management systems, the conventional throttle sensor plays an important role in its relationship with other sensors. The voltage inputs of most throttle position (TP) sensors may, for example, be coordinated with the barometric pressure (BARO), manifold absolute pressure
