The PCM Effect on Oil Service
As with everything else under the automotive sun, technology is changing the lube, oil and filter market. More specifically, modern technology is making it possible to use the vehicle’s on-board engine management system to mathematically determine the length of an oil change interval. At the most basic level, the PCM simply adds up the mileage
Tech Tip: Thermostat Technology
Although the humble thermostat isn’t generally considered to be a "high-tech" component, it continues to serve a number of very critical functions in the modern, computer-controlled import vehicle. To better understand these functions, let’s first consider that carbon and water are two major by-products of internal combustion that accumulate in an engine’s motor oil.
Tech Tip: Ford Engine Oil Levels – How to Avoid Overfilling
Incorrect oil levels are being found in many 2002-2003 Ford, Lincoln and Mercury vehicles. In most cases, the level is being misinterpreted because the oil level on the dipstick is not touching the top hash mark at the upper limit (or MAX mark), or it is partway down the crosshatch area.
Tech Tips: Brake Lubricants – High Temperatures Require High Performance Products
When it comes to brake lubricants, grease is a dirty word. Brake lubricants are specially-formulated products that are NOT the same as ordinary chassis grease or even multi-purpose grease.

Tech Tip: Regular Fluid Flushes are Good for Transmissions
Out with the old and in with the new. Transmission fluid flushing is a service that replaces old worn-out automatic transmission fluid (ATF) with fresh new fluid to prolong the life of the transmission. Considering the fact that it costs $1,500 to $2,200 or more to replace a transmission or transaxle these days, the cost of a fluid flush is peanuts by comparison.
Tech Tip: Replacement of Gear Lubes Can Prevent Expensive Driveline Problems
The lubricants that are used in manual transmissions, transaxles, differentials and transfer cases include a variety of different oils. Most of these lubricants are long-lived and hold up well for tens of thousands of miles. But none will last forever. The combination of heat, shearing action and oxidation eventually breaks down the oil and reduces its ability to lubricate and protect.
Tech Tip: Water Pumps – Why They Fail and When to Replace Them
If you’ve wondered how much work a water pump must do, remember that only about 30 percent of the heat energy produced by combustion results in mechanical energy. That estimate, of course, is a mathematical comparison between the heat value of the gasoline going into the engine, and the heat value of the mechanical energy coming out of the engine. The remainder of combustion heat must then be dissipated into the atmosphere through the exhaust, lubrication and cooling systems.
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
