Diagnostic Solutions: Building Off-Road Suspension Systems

Judging from weekend traffic, desert off-road and mountain trail driving is becoming a major past-time for many import vehicle enthusiasts. Most of the off-road import vehicles I see in Colorado are the late ’80s and early ’90s Toyota and Nissan pickups and SUVs that feature mechanical simplicity along with the structural ruggedness needed to navigate miles from any service facility.

Diagnostic Solutions: Alternator Testing Tips

When we’re attempting to diagnose a charging system failure, it helps to think of the battery’s state of charge (SOC) as a type of checking account. If we overdraw our account, we wake up the next morning with an engine that won’t crank. Or, if we overdraw our account and not balancing our account at the end of the day, we again are greeted with a slow-cranking engine and an overdrawn charging system account.

Tech Feature: Valve Timing Terror Tales

While a lot has been written about timing belt replacement intervals, not a lot has been written about diagnosing timing belt and valve timing-related driveability complaints. In this article, Gary Goms reports that he is beginning to see more driveability problems caused by faulty valve timing.

Diagnostic Solutions: Conducting Non-Intrusive Cooling System Inspections

Perhaps the best way to begin when we get a cooling system overheating complaint in our service bay is by using a series of quick, non-intrusive cooling system tests that establish the basics without removing major parts.

Talking Shop: An All-Access Pass to Shop/Repair Information?

If you’ve spent hours struggling to master a new computer software system, you can well understand how a modern auto technician might feel when confronted with not just one, but hundreds of different software configurations built into the platforms of the 17 different vehicle manufacturers now being sold in our domestic market.

Tech Feature: Identifying Suspension Bushings that Cause Squeaks, Knocking Noises and Vibration Complaints

Worn or hardened suspension bushings can cause many mysterious squeaks, knocking noises and vibration complaints. Unfortunately, in their rush to sell ride control products like MacPherson struts, shock absorbers and springs, techs often forget to inspect and replace rubber suspension bushings, explains Import Specialist Contributor Gary Goms.

Tech Feature: Lack of Power Leads to Exhaust Restriction Analysis

In the early days of carburetors and mechanical fuel pumps, most lack-of-power complaints stemmed from vapor locking on the fuel pump or the fuel filter clogging. But that’s becoming the exception rather than the rule.

Tech Feature: The Nuts and Bolts of Belt and Hose Service

Today, belts and hoses are a routine inspection item and may not need replacement even at 100,000 miles or more of service. Unfortunately, many vehicle owners and technicians forget that heat, load, pressure and atmospheric pollutants eventually deteriorate a vehicle’s rubber parts.

Brake Tech Feature: Rotors and Friction Service

Years ago, a brake replacement would pass muster if it allowed a vehicle to stop in a reasonable distance at highway speeds. Today, a brake replacement must meet consumer-oriented criteria in areas of braking noise, pedal sensitivity, side-to-side pulling, pedal pulsation, frictional qualities, fade resistance, wheel dusting and friction longevity.

Ignition Sensor Diagnostics: Variable-Reluctor, Hall Effect and Magneto-Resistive Sensors

Although ignition failures are relatively common, they’re not the easiest problem to diagnose. To help you get started on what I call a “systems approach” to ignition diagnostics, this article is intended to provide an overview of how to identify ignition system configurations, identify three different types of ignition sensors and understand several basic sensor-operating strategies.

Catalytic Converter Tech Feature: Diagnosing P0420 or P0430 DTCs

Although modern OBD II technology has simplified catalytic converter diagnostics, it’s still important to understand the basics of catalytic converter operation when dealing with a P0420 or P0430 DTC. Gary Goms explores the basics of catalytic converter chemistry and summarizes how common converter failures can be diagnosed.

Tech Feature: Diagnosing the Blue Car Syndrom of a Random Stalling Condition

Blue Car Syndrome is the non-technical term for a very common phenomenon. It is the experience that many people possess regarding having a specific observation, idea, experience, etc., enter one’s consciousness, and then having it seem that the same observation or experience begins to occur with increased frequency.
