Under Pressure
According to the U.S Department of Transportation, cooling system failures are the number one cause of vehicle breakdowns on the highway. Many of these breakdowns are attributed to coolant leaks (hoses, radiators, bad radiator caps, etc.), water pump failures, thermostat failures and defective cooling fans. An industry survey conducted in 2003 by 1-800-Radiator reported that
Servicing Maintenance-Friendly VW Engines
Volkswagens have always been maintenance friendly. From the very first models, ease of repair and durability have been built into the design. VW has managed to keep basic maintenance procedures relatively uncomplicated throughout the years. In this article, I’ll cover some of the more common underhood procedures on common VW models and include some tips
Brake Lubricants
How a little lubrication can turn you from a zero to a hero.
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
Advances in Piston Ring Technology
Piston rings have one of the toughest jobs inside an engine. They’re slammed up and down between the ring lands thousands of times a minute, they’re subjected to searing temperatures and extreme pressures, and they’re constantly scraping back and forth against the cylinder walls. In spite of all of this, the rings are expected to
Olds Engines: Gone But Not Forgotten
By Larry Carley Times change and vehicle makes and nameplates come and go. The last official Oldsmobile rolled off the assembly line on April 29, 2004, when General Motors pulled the plug to stop the hemorrhage of red ink in their ailing Oldsmobile car division.

Servicing Ford 4-Cylinders: Contour, Escort, EXP, Focus, Probe, Ranger & Tempo
Ford has used a variety of four cylinder engines over the years, ranging in displacement from 1.6 to 2.5 liters (see engine application chart on page 22). All of these engines are overhead cam engines, some with a single cam others with dual cams, and all have timing belts that need to be replaced at
Performance Upgrades: Tuning, Tweaking & Boosting Your Way to New Profits
The import performance market offers a unique service opportunity for you. Import vehicle owners are accessorizing their vehicles like never before, and many are buying aftermarket performance parts in record numbers. Though many of these parts are sold to people who can install the parts themselves (things like wings, spoilers, lights, big bore mufflers, etc.),
Timing Belt Replacement: Safeguarding Your Customers’ Vehicles From Major Engine Damage
Although better materials and manufacturing technology have extended the timing belt replacement intervals on many nameplates, timing belt replacements remain one of the most profitable scheduled maintenance services. They continue to be profitable because many other scheduled services like spark plug replacements, filter replacements, coolant changes and transmission fluid changes can be packaged with a
Piston Technology: To Power Today’s V8s
The performance piston business today is hot thanks to a strong racing market and the introduction of new OEM engine families such as Chevy’s LS1/LS6 V8s, Ford’s 4.6/5.4L V8s and Chrysler’s Hemi. Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston designs to reduce weight, and
