Examples of applications include: Interior or exterior panels/clips, with applications including...

Today's vehicles feature a lot of plastic, in terms of panels and snap-in clips. Popping panels from interiors or trying to remove push-pin plastic clips that retain headliners, seals, etc., can be dicey when using metal tools such as screwdrivers.


Wheels and NVH -- How to make a vehicle ride like new again

Figure 1: Clean the rotor hub where it contacts the wheel and fits through the wheel center.

When driving a new vehicle, one of the first things you notice is how smoothly it rides. That new-car ride is mostly the result of a tremendous amount of engineering that goes into eliminating noise, vibration and harshness, otherwise known as “NVH.” Of course, as that smoothness gradually fades, most people assume it’s just a consequence of the car’s age and mileage.


Mazda Skyactiv Technology -- What it is, and What it Has Meant to Engine Packages

Skyactiv G gasoline engine.

I am sure that by now almost all of us have seen or heard the advertising of Mazda’s Skyactiv technology, but how many of us actually understand what it means? If you’re a full-time Mazda tech or just a Mazda aficionado, then this will just be a lot of review for you. But for the average tech who doesn’t specialize in just Mazda’s latest vehicles, I want to explain what is meant by Skyactiv technology, and what changes it has meant to the engine packages.


Tool Review: MAHLE TechPRO

The TechPRO VCI and the Surface tablet. The tablet measures 11 1/2 x 8 x 3/4 inches.

There are scan tools, and then there are scan tools, and then there is MAHLE’s TechPRO. When the company’s ads tout the “game changer” aspect of this system, they were not blowing smoke or employing over-stated hype.

This is the current four gas test bench that we use for exhaust emission testing for vehicles...

The actual combustion process that takes place in the modern vehicle with a gasoline engine hasn’t changed much since the four stroke engine was invented well over 100 years ago. Yes, it’s been immensely fine-tuned to reduce the pollution that it creates and increase the fuel economy that we get when we fill up the tank, but the exhaust that is created is the same. When gasoline as a fuel is burned, chemically we should only get a few things; water (H2O) carbon dioxide (CO2) and heat.
