VIDEO: Stop Chasing Codes With Components
When it comes to misfire codes, it might be tempting to replace or swap parts like ignition coils and engine sensors to get rid of a code. But, you might actually cause new problems instead of curing the original problem. Andrew Markel covers why finding the root cause of a code is more productive than chasing problems with replacement parts. Sponsored by Auto Value and Bumper to Bumper.
VIDEO: No Nut Or Washer Left Behind
If you are installing a new strut, mount or brake caliper, it is important to use everything that comes in the box. This is important because some nuts and bolts are one-time-use items. Also, the new component might use better fasteners than what originally came on the vehicle. Sponsored by Auto Value and Bumper to Bumper.
VIDEO: Inspection Before Disassembly
One of the most forgotten steps before replacing a head gasket is to inspect the entire engine before removing the head and intake manifold. Andrew Markel covers what to look for under the hood, under the car and in the ECM. Sponsored by MAHLE.
VIDEO: Turbocharger Turbine Damage
The signs of a damaged turbocharger could be noise, loss of power and codes related to a loss of boost. Sponsored by Auto Value and Bumper to Bumper.
VIDEO: What Can A Donut Do To A Drive Belt?
Everybody loves a full-lock drift or a smoky donut, but keeping the steering at full lock can have implications for the power steering pump and belt. Andrew Markel explains how power steering fluid can become superheated and damage the pump. Sponsored by INA, a Schaeffler brand.
VIDEO: When Is A Clunk From The Air Conditioning Compressor Abnormal?
Some customers may complain about a clunk coming from under the hood when they are not moving or at low speeds. Some noise is normal. But, if the drive belt or tensioner are worn it can make the noise louder. Andrew Markel covers how to diagnose the drive belt system and compressor. Sponsored by INA, a Schaeffler brand.
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. Sponsored by INA, a Schaeffler brand.
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. Sponsored by ProDemand from Mitchell1.

The change in the loading of the bearing can result in damage and failure of the belt system. Sponsored by INA, a Schaeffler brand.
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. Sponsored by NAPA.
VIDEO: Determining Unrelated Codes By Ground Distribution
If you have several unrelated codes or problems, you can diagnose a vehicle faster by checking the grounds first. Sponsored by ProDemand from Mitchell 1.
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. Sponsored by NAPA.
