VIDEO: Choosing The Right Battery
Finding the right battery for the vehicle’s unique needs is vital for keeping your customers on the road. It’s extremely important that your replacement batteries meet or exceed the requirements of the Original Equipment.
VIDEO: Oil Filter And Noise At Start Up
If you have a vehicle that comes to your shop with valvetrain noise at start up, the solution might be simpler than you think. Many engines have variable valve timing, these systems need to have engine oil to operate. If the oil drains from the top end of the engine, the actuators and lifters will make noise when the engine is started. The cause could be a damaged oil drain back valve in the oil filter.
VIDEO: Understanding Drive Belt Decouplers
In this video, Andrew Markel discusses a new drive belt service opportunity. Many small engines and diesel engines are coming with decoupler pulleys on the crankshaft that are a mixture between a dual mass flywheel and an alternator decoupler pulley. The pulley can reduce vibrations in the crankshaft and the drive belt system.
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: 5 Tips For Ignition Coil Replacement
When replacing an ignition coil, there are a few things to keep in mind that you might overlook that prevent premature failure.
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: Top 2 Reasons For Ignition Coil Failure
In a new episode of Tech Test Prep, Carley Millhone shares what you need to know about ignition coil failure to pass the A8.
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: 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.
