Tool Review: Mac Tools cordless 3/8-inch wrench

The range of high-quality cordless electric power tools is quickly expanding. Torque and battery life is increasing, and the toughness and durability demanded by pro technicians is increasingly being met. To provide insight into a new offering, here we’ll review one of the latest Mac Tools cordless impact wrenches.


How electronic stability control can improve ride control sales

Electronic stability control (ESC) is nothing new. Introduced as optional equipment on luxury cars in the mid-1990s, it’s been standard on light-duty truck and passenger vehicles since 2012.


Check engine light diagnostics

For most auto repair shops, diagnostics are not where the money is. A good diagnosis is needed to figure out what parts (and these days, sometimes software files) are needed to repair a drivability issue.


Advances in ride control: Getting up-to-speed on electronic suspension control

Once upon a time, ride control simply referred to providing a vehicle with a comfortable driving experience while limiting excess body roll. This was primarily addressed by the automakers by the selection of the appropriate springs, shock absorbers that would dampen spring movement and anti-roll bars that somewhat tamed, or limited, excess body lean during turns or steering maneuvers.


Brake pad and rotor technology

Today’s brake pad formulations continue to evolve, but the basics include organic, non-asbestos organic (NAO), semi-metallic and ceramic.


Battery testing basics

The cold snap that recently swept through most of the nation caught many folks unprepared as roads closed, pipes burst and batteries failed.


You added what?

The ignorance of some customers continues to amaze. A buddy’s shop recently took in a 2001 Honda Accord with a “no brakes” issue. The car was towed in on a flatbed, since the customer was afraid to drive it to the shop.


Scion charcoal DTC

Some 2010 model year Scion xB, xD and tC vehicles may exhibit a MIL on condition with DTC P2420.


‘Been there, done that’ -- Advice from experienced service technicians

We had a 2004 Chevy Silverado 2500 in the shop, equipped with the 6.6L Duramax diesel engine. The MIL was on and the vehicle exhibited intermittent low power. Code P1093 was stored, which indicated low fuel rail pressure during power enrichment.


Road work can be a good thing

Along, seemingly endless line of orange barrels or concrete barriers on a highway is never a pretty sight. It generally translates into traffic backups and longer commute times. However, there’s a bright side to this often aggravating scenario, with regard to demand for automotive repair.
