By Dave Hobbs. Oil spills in the Gulf of Mexico and continual conflict in the Middle East always mean the same thing – fuel prices aren’t going down, and will most likely increase in months and years to come. Combine that with increased CAFÉ standards, and you have the ultimate recipe for changing powertrain technology. Alternative fuels, turbocharged small engines, clean diesels, hybrid electric and pure electric are all examples of new technologies to increase efficiency. Whether one of these technologies will win over the others, or there will be a combination of technologies on the road, it is a sure thing that hybrids electric vehicles are gaining popularity. For the service professional, like them or not, they’re here to stay. That means opportunity for the automobile HVAC technician willing to keep up with the changes they present.

By Dave Hobbs. If you’ve made a New Year’s Resolution to increase profits at your shop by finding new repair opportunities, look no further than hybrids. It’s predicted that by the end of this decade, over 25 percent of all new vehicles produced will contain some type of hybrid electric technology. In the December 2010 MACS Service Reports, we took a dive into the HVAC system on the Toyota Prius line, along with a quick overview on how hybrid vehicles work in general. We also covered safety tips, electronic controls and the Gen II Prius electric compressor. This month, we’re going to dive in deeper.

Following a new clutch installation, there is nothing worse than experiencing slipping or release problems. Many times installers even begin to believe that the new clutch kit is defective. This is not correct, in most cases!

If you watch any amount of television, you’ll notice that this is the time of the year that new vehicle dealerships are pushing out their old inventory to get ready for the 2014 models.

In the world of public opinion, if you were asked if your technicians were overcharging your customers, you might interpret that as an issue pertaining to the customer’s repair bill.

Thanks to the increasing reliability of modern vehicles, most diagnostic technicians are seeing fewer pattern-failure driveability complaints.

Two states have passed laws, and more are looking:
California was the first state to enact a law regulating copper and other substances in brake pads. Washington was not far behind with an even more detailed law. Hawaii, New York, Rhode Island, Oregon and even countries are considering their own laws.

AVI would like to thank everyone who attended the Toyota EVAP Livestream. If you didn’t get a chance to see it you can follow the links below and catch a replay of the event. AVI looks forward to bringing more of the events to the online viewers in the future hope that you will join us and make the next event just as exciting as this one.

Bob Pattengale from Robert Bosch, LLC will be covering Toyota EVAP Diagnostics: geared towards automotive service technicians
Hosted at AVI OnDemand, FREE to all (Free AVI OnDemand account required) February 13th, 6pm-7pm EST followed by Q & A.

Throughout the evolution of the modern ­vehicle, there have been an increasing number of duties taken over by computers. These computers have not only made the ­engine more fuel efficient, but also more environmentally friendly. Nowadays, these systems are starting to “think” for themselves and make decisions for the driver.

The time to change to and from snow tires is both a regional and personal decision. Whenever it takes place, a changeover brings with it a need for consumers to make some decisions. To purchase or not purchase a second set of wheels needs to be followed with questions about TPMS sensors.

By Gary Groms. I’m no doubt showing my age, but the phrase, “it’s not your father’s Oldsmobile” keeps popping up in my head each time I get a call to solve some type of modern-day Diagnostic Dilemma.

By Andrew Markel. Join Andrew, a former technician and service writer, and uncover nine great tips you should consider when performing TPMS work. Find out how to create more revenue, boost productivity and best of all, reduce customer comebacks.

By Scott ‘Gonzo’ Weaver. Do you remember a time when we didn’t have a malfunction indicator light on the dash? If you do, then you would also remember the thick, heavy smog of California’s valley cities and the stench from an exhaust pipe while sitting at a traffic light. Technology and the family vehicle have come a long way from the days of belching high amounts of NOx, CO and HC out of the tailpipes.

By Gary Goms. Most of us working in the automotive service trades are very familiar with Murphy’s Law and how it affects our shop’s cost of doing business. Murphy’s Law says, “Everything that can go wrong usually will go wrong.”

By Gary Goms. During the past century, ignition coil configurations have evolved from oil-filled canister to epoxy-filled to e-core to waste spark and to the most modern coil-on-plug or “pencil” coils. Whatever the configuration, an ignition coil creates a spark by transforming amperage into volts.

By Frank Walker. As you may know, the air conditioning compressors in many hybrid vehicles are operated by an electric motor instead of a drive belt. The motor’s insulated windings are immersed in the compressor’s lubricating oil. The oils used in these compressors are formulated to have high dielectric properties, that makes them non-conductive.

By Scott ‘Gonzo’ Weaver. By the early 1990s, almost all import automotive manufacturers had a successful variable valve timing (VVT) system in production. These systems offered higher performance from smaller displacement engines at higher rpm. As these vehicles exceeded their new car warranties, technicians learned the ins and outs of these systems and how regular oil changes could increase the life of VVT components. Now, the VVT is playing a direct role in vehicle emissions and the way gases are burned in the combustion camber.
