Tech Feature: Curbing Catalytic Converter Thefts

Catalytic converters have been disappearing at an alarming rate. The theft of these emission control devices is being perpetrated by sleazeballs looking for easy money. A thief can hock a pilfered converter for $25 to as much as $100 depending on the value of the precious metals inside it.

Directions: Turbocharging’s Not Just A Lot of Hot Air

In a recent study of U.S. consumers by Honeywell, more than half of those who plan to purchase a vehicle in the next two years believe fuel efficiency is more important than it was during their last vehicle purchase.

Delphi Expands its Condenser Product Lines and Enhances Mass Air Flow Sensor Technology

Condenser expansion delivers 75 percent coverage; redesigned mass air flow sensor improves performance and fuel economy.

DENSO Sales California Releases New 2009 Oxygen Sensor Catalog

Along with additional coverage, the DENSO 2009 catalog offers an updated 180-page illustration guide to assist with sensor selection.

Tech Feature: Getting The Most Data From Your Scan Tool

It’s more than likely that many technicians use their scan tools as diagnostic trouble code (DTC) readers rather than as the analytical and testing tools that they really are.

Tech Feature: The Subaru Boxer Engine: A Balance of Power

According to their engineers, these high-powered engines are ideal for all-wheel-drive applications used in Subaru vehicles because they are inherently compact – short and low.

Tech Tip: Wave Dynamics for Headers and Pipes

Depending upon the market to which an import shop might be catering, the term “performance exhaust” can have two different meanings. The first market actively seeks out the throaty rumble and chrome-plated look as part of the street-driving scene. The second market installs an exhaust system that produces the most horsepower for a performance application. Sometimes the two markets are identical and sometimes they’re not.

Tech Feature: Servicing Diesels in Your Shop

Is there a diesel in your service bay? Maybe not now, but there definitely will be in your future. You’re going to see trucks as well as SUVs and passenger cars. Mercedes-Benz produced a 3.0L V6 diesel-powered SUV for the 2008 model year and Volkswagen has a Twinturbo 5.0L V10 diesel engine in its Touareg. As the automakers focus on better fuel economy, you might say the diesels are coming again.

Tech Feature: Manifold Makeover – Increasing Engine Power

An intake manifold is more than the plumbing that connects the carburetor or throttle body to the ports in the cylinder head. It is an integral part of the induction system that has to match the airflow characteristics of the cylinder head and camshaft, as well as the displacement and rpm range of the engine. A well-designed manifold that is properly matched to the engine’s requirements will make more torque and horsepower than a manifold which is mismatched to the engine.

Tech Feature: What’s New in Spark Plug & Ignition Cable Technology

Ignition systems have changed a great deal in recent years, with coil-on-plug (COP) ignition systems being the most common setup on many late-model engines. Car makers like COP ignition systems for a variety of reasons. The main one is that mounting a small ignition coil over each spark plug gets rid of the troublesome spark plug wires. Plug wires are vulnerable to heat and vibration damage, and can become a source of ignition misfire if they become wet.

Electrical System Testing Tools and Equipment

One day we are fat, dumb and happy using a piece of wire with a 12-volt bulb on the end of it to test things with. Now we are faced with deciding between using the 10 meg-ohm computer safe test light, the power injector or a logic probe complete with polarity protection, audible alarm, light and 20-foot memory cord. Geeesh! How did things get so confusing so fast? Progress my boy! That is the root of our problem here! As the cars and systems have gotten more and more complicated, so have the tools and equipment needed to work on those cars ….

Diagnostic Solutions: Rediscovering Oxygen Sensors

If you’re like me, you more often than not find a correct diagnostic direction by going back to what trainers are fond of calling “The Basics.” I capitalized “The Basics” because they are the foundation upon which all of us should be building our diagnostic strategies. The Basics were brought to mind recently when I
