VIDEO: Determining Turbocharger Failures

When a turbocharger fails, your CSI skills must be put to work. Determining why it fails may be much more difficult than replacing it.

VIDEO: Replacing Fuel Pump To Solve Slow Acceleration

A customer comes in a complains about not being able to speed up quickly when applying gas. Your first thought might be to change the fuel pump, but sometimes that isn’t enough. Andrew Markel explains how it could be an internal leak.

VIDEO: Understanding Oxygen Sensors And Air Fuel Ratio Sensors

Early oxygen sensors could only see a very narrow range of the air/fuel ratio. Modern air/fuel ratio sensors can see a wider range of lean and rich conditions. Andrew Markel discusses what this means to your diagnostic approach when it comes selecting the correct sensor for the job.

VIDEO: How Turbocharger Efficiency Is Affected By Location

Today’s 4-cylinder engines can generate more torque and horsepower than yesterday’s V-6 engines and turbochargers have made a comeback. Their location under the hood will determine lifespan and efficiency. Doug Kaufman explains why the placement of the turbocharger is so important.

VIDEO: Cavitation Breaks Down Your Water Pump

Andrew Markel explores how tiny cavitation bubbles can damage a water pump. He also offers up three methods to control cavitation to make sure the replacement pump lasts a long time.

VIDEO: Determining Unrelated Codes By Ground Distribution

Typically, a lot of the components in a vehicle are shared by the same grounds. If you have several unrelated codes or problems, you can diagnose a vehicle faster by checking the grounds first. Andrew Markel explains why and how this is possible.

VIDEO: Brake Pad Wear Specification

Andrew Markel explains how minimum wear and discard specifications of the brake pads and rotor (disc) are related to the caliper and piston. If a technician fails to measure the rotor when the pads are replaced, it could cause a hydraulic failure when the pads wear out.

VIDEO: How Modules Manage Alternator Power

Andrew Markel discusses power flow through the electrical system on a vehicle, and how the modules help provide the right amount of power to different components.

VIDEO: Replace The Thermostat With Every Cooling System Job

Andrew Markel discusses the limited lifespan of thermostats, and how that makes it necessary to replace the thermostat as part of a cooling system task.

VIDEO: Best Practices For Turbocharger Life

Doug Kaufman discusses some simple things your customers can do to ensure the longest life of their turbochargers.

VIDEO: Ensuring Your Alternator Lasts

Sometimes, there is more to replacing a part than just a simple swap. Andrew Markel explains why you should follow a few more steps after replacing an alternator. Check out this video to learn more ways that you can ensure your new alternator will last longer than ever and that the electrical system will stay up to par.

VIDEO: Understanding Variable Geometry Turbocharging Technology In Modern Engines

Doug Kaufman explains the concept of performance and efficiency of different engines.
