VIDEO: Brake Bleeder Screw Removal Methods And Strategies
On some cars and trucks, trying to crack the bleeder screw can be a gamble. Either the screw will not budge or it snaps like twig. In this video, Andrew Markel discusses six tips to make dealing with bleeder screws more productive and profitable.
VIDEO: Drive Axle Inspection, Diagnostics And Installation
Andrew Markel discusses the total repair process for axle shafts. CV and tripod joints hardly ever fail on their own. The failure of the joint or axle can be caused by a faulty mount, suspension or steering component. It is critical that the problem is solved before the new axle is installed.
VIDEO: Check Wiring Diagrams Before Probing
If an electrical issue is confusing you, Andrew Markel says it is important to reach for wiring diagrams before reaching for a probe, to prevent unnecessary damage to wires and connectors.
VIDEO: Better Bulbs For Older Cars And Shorter Days
It is that time of the year when the days grow shorter and drivers need their headlights more. Andrew Markel discusses how shops can upgrade old headlights with bulbs that help drivers to see more on the roads with better contrast.
VIDEO: Timing And Drive Belt Idler Pulley Bearing Loads
Both timing and drive belt systems use idler pulleys to tension and control the movement of the belt. If components on the timing or drive belt system are misaligned, the loads on the bearings are changed. The change in the loading of the bearing can result in damage and failure of the belt system.
VIDEO: What Does A Three-Way Catalytic Converter Reduce?
If a three-way catalytic converter is functioning properly, only nitrogen, carbon dioxide and water should be coming from the tail pipe. In this video, Andrew Markel covers the basic chemistry that is happening inside a catalytic converter.
VIDEO: Diagnosing Drivetrain Stabilization
The angles of the universal and cardan joints on a driveshaft have a limited range of motion. If the angle of the pinion, transmission or axle exceed the specifications, it can result in noise and damage to the drivetrain. Andrew Markel shows how a worn motor mount or damaged axle can result in a customer noise compliant.
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.
