Viewpoint, AAMCO, Cottman, Monro, Procare: With Size Comes Responsibility
In the past month, we have seen some historic events in the world of undercar service. The reunification of Cottman and AAMCO and the acquisition of ProCare by Monro Muffler have changed the landscape of the undercar service industry. Some people say that the Cottman and AAMCO deal was a shocker. When Rich Silva (Cottman)
Diagnostic Solutions: Profitable Radiator Service…Targeted Troubleshooting Procedures Are a Must
Unlike their soldered-brass predecessors, today’s aluminum-core, plastic-tank radiators are not only environmentally friendly, they are lightweight, easy to service, less costly to produce, and very efficient at keeping modern, high-output engines operating at optimum temperature. Because of their affordability and because they can be inspected while removed for a timing belt replacement or other front-mounted
Kia Maintenance & Service Solutions
MASTER CYLINDER DIAGNOSIS Easy Fixes For Elusive Intermittent Problems While Kia offers a 100,000-mile powertrain warranty, well-documented maintenance is an important part of keeping that warranty valid. With regular maintenance required at 30,000 miles and timing belts at 60,000 miles, owners will be looking for quality service. Rather than delve into the service nuts and
Tech Feature: Solving Intermittent Electrical Problems
Intermittent electrical faults are the bane of the auto repair business. If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn’t hiding from you. It’s a persistent fault that can be isolated by a systematic process of elimination.
TechTalk: A Chevy Tahoe with Shifting Issues
A customer with a 1996 Chevy Tahoe brought the vehicle in, stating that it was shifting erratically, the cruise control would surge from 50 mph to 60 mph and then cut out completely and the speedometer, at times, was drifting. (This Tahoe had a 5.7L vin R engine with a 4L60E transmission coupled to a
Getting Tanked: Flex Fuel Engine Modifications Allow for Alcohol-Based Fuel
In case you haven’t heard, Flex Fuel technology is really starting to take off in the U.S., becoming more popular in late-model vehicles than technicians may realize. If you haven’t had any training on these vehicles, you may find some of the technical changes OEMs have made to the engines will alter the way you
Alternator Diagnosis: High-Draw Accessories Merit Changes in Test Procedures
As the saying goes, “Old habits die hard.” Among the old habits that die hard is the way we test alternators. In the past, the job of the alternator or generator was simply to recharge the battery after start-up and carry minor accessory loads such as ignition, lighting, radio, heating or air conditioning clutch, and
Bad Gas Update
How bad can it get? When the price of gasoline soared to over $3 a gallon after hurricane Katrina, people were shocked. They actually began to change their driving habits to conserve fuel by eliminating unnecessary trips, sharing rides to work, staying home in the evening instead of going out and doing what little they
Diagnostic Solutions: Identifying Ignition Switch Failure Symptoms
Although the basic ignition switch has remained unchanged for many years, the way it supplies electrical current to modern on-board electronics has made it a key factor when diagnosing intermittent failures in various electronic operating systems. Going back into automotive history, the ignition switch’s sole purpose on early imports was to energize the primary ignition
Battery Breadkown
A battery breakdown is bad news. If the battery can’t supply enough amps to crank and start the engine, your customer’s vehicle isn’t going anywhere (except maybe downhill powered by gravity). A good battery is absolutely essential for reliable starting and for powering the vehicle’s onboard electronics and electrical systems when demand exceeds the charging
Under Pressure: Maintaining Ford’s Electronic Returnless Fuel System
By Glen Beanard, Technical Contributor Here we go again. A simple electric pump pushing fuel up to the engine, with its pressure being controlled by a little valve, and returning the unused fuel to the tank was not good enough. Now, we need to make that all fancy by adding a new controller, adding a
Alternator Altercation Electricity Fundamentals
Electrical principles, like voltage, amperage and resistance, can be described as cars passing along the roadway. Voltage was referred to as the vehicle’s speed, amperage as the number of vehicles on the road at the same time, and resistance as potholes in the road’s surface. Basically, electricity is a supply of atoms with an excess
