If It’s December, It’s Really Next Year Already — Taking Stock of 2009
Here is Publisher Beth Skove’s take on this year’s Top 5 Events and Influences.
Tech Tip: Diagnosing an Engine that Won’t Start
For any engine to start, three things are necessary: fuel, compression and spark. If any of these components is lacking, the engine won’t start. The fuel system must be generating normal fuel pressure, and the air/fuel ratio must be correct for the ambient temperature and engine temperature. If the air/fuel mixture is too lean, it won’t ignite and the engine won’t start. If the air/fuel mixture is too rich, it can flood the engine and also prevent it from starting ….
Nissan: Head Gasket Replacement Procedures
With the reliability that late-model cars and especially their engines enjoy, we don’t find ourselves doing too much heavy engine work anymore. Many of us miss the feeling of accomplishment we’d get when completing an in-house engine rebuild. I know I always enjoyed the moment when the fresh engine would light right off and run
BMW Engine Repairs
Though six-cylinder, inline engines are not as popular today as they were just 25 years ago, their sound and layout still translates well into high performance, durability and smoothness. The six-cylinder M50 series was originally used in 5 series cars in the early 1990s, and is now the basis for the 3 and 5 series
Hybrid Service: Tools to Service Hybrids
As the price of gasoline goes up, so does the demand for fuel-efficient hybrid vehicles. Currently, there are about 1.1 million hybrid vehicles on the road. Within five years, hybrids are expected to account for 20 to 25% of all new car and light-truck sales. So sooner or later, you’ll be tooling up to work
Tech Tip: What To Do When An Engine Won’t Start
In today’s world of high-tech electronics, onboard diagnostics and scan tools, you would think engine diagnostics would be easier than ever. Yet some technicians struggle when confronted with an engine that cranks, but refuses to start. Most no-starts do not generate any fault codes, so how do you proceed to find out what’s causing the problem?

Scan Tools: Scan Tools Offer a Window Into a Vehicle’s Inner Workings
Scan Tools Offer a Window Into a Vehicle’s Inner Workings Larry Carley, Technical Editor [email protected] Technicians who attempt to make driveability or emissions repairs today without a scan tool are troubleshooting in the dark. A scan tool is absolutely essential because it provides a window into the inner workings of the engine management and onboard
Tech Tip: Understanding Vehicle Electrical Systems Begins and Ends with the Alternator
The alternator’s job has definitely become more complex during the past decade. Years ago, the typical import vehicle could live very happily with 40 amps of electrical current, which was enough to power the ignition, fuel and lighting systems. Today, that threshold is rapidly advancing toward 100 amps of current.
Top Five Tools
