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.
Wheel Bearing Failure Diagnostics
On a typical passenger vehicle weighing around 3,400 pounds, each pair of front-wheel bearings, as well as the rear-wheel or axle bearings, support saround 850 pounds, depending on the weight balance and driveline configuration. If it’s a 6,000-pound SUV, each bearing might carry about 1,500 pounds. This load is concentrated on the relatively small bearing
Publisher’s Perspective, Competition for Tomorrow’s Technician Intensifies
Here’s the headline in my local paper, “Construction skills in high demand. Industry intensifies recruiting of high schoolers.” The article goes on to say that many trade groups and employers are actively recruiting high school students to fill the growing need for plumbers, bricklayers, drywallers and other traditional trades. But it should be no surprise
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
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
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
Fuel Pump Diagnostics
Electric fuel pumps are a vital part of any electronic fuel injection system because achieving an accurate air/fuel mixture ratio depends upon the fuel injector receiving adequate fuel pressure and volume. Because electric fuel pumps have moving parts that wear out, they also have a relatively predictable service life and, therefore, become a predictable profit

Selling Services: Selling the Scope to Your Customer
While replacing a blown head gasket and re-torquing the head bolts, you reach into your tool box and grab your 1/2-inch impact and rattle the bolts down. Just kidding! You would reach for your torque wrench and accurately follow the manufacturer recommendations for torque patterns and values. To guarantee a quality repair, an accurate torque
Component Connection: 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% 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
Handling the Load
It takes a lot of amps to power the lights, electric defrosters, wipers, power windows, power seats, power liftgates, the ignition system, fuel injectors, fuel pump, cooling fan, A/C compressor, heater fan, heated seats, audio system and navigation systems on today’s late-model vehicles. Since alternators can generate only so many amps, their output may depend
