Tech Feature: Subaru Service Essentials
My stint at being a service advisor for a number of dealer service departments over the years gave me a lot of experience in “bundling” services into a package. Having a service plan or “menu” built value for the customer. It also provided the service department with reliable income. Though there are good and bad points to service menus, the basic idea is a good one, and works well for any kind of automotive service or repair facility.
Preemptive Diagnostics: Solving Pulsation Complaints Before They Happen
Here is a scenario: A shop performs a brake job on a vehicle. The front pads and rotors are replaced. On the test drive, the vehicle had zero signs of pulsation, even after an aggressive break-in procedure. Six months and 6,000 miles later, the customer is back complaining of a pulsation in the pedal. So what has happened in 6,000 miles?
Tech Feature: Transmission Fluid and Filter Service
To prevent any service from being over sold or under sold, it is important to not only know that a particular service should be performed, but also why it should be performed. That knowledge can also help you spot when to recommend that service, and when not to. When speaking about transmission fluid, the short version of the explanation is that it gets dirty and wears out.
Tech Update: Working on Wipers
It’s right after a major snowstorm, and there’s ice and snow on everyone’s windshield. You’re at the shop waiting for the phone to ring. The phone leaps off the receiver and it’s Captain Chaos; he’s managed to find a second use for his wiper blades. Apparently, Captain Chaos was in too much of a hurry to clean the ice off the wiper blades before turning them on. In his frantic attempt to go to work, the wiper blades have become completely useless. He can hear the wiper motor running, but the blades refuse to move.
Tech Spec: Tackling Old Timers – Salvaging Pre-War Era Engines
It’s often surprising to some people that parts for these cars are still available. For other engine specialists, it’s sometimes more surprising when they aren’t.
Brake Job: Dodge Magnum/Challenger/Charger
The 2005-current Chrysler rear-wheel-drive LX-Platform. The LX platform includes the 300, Magnum and Charger. In 2008, the platform was shortened for use in the LC-platform that was used in the Challenger platform. All have rear disc brakes with the parking/emergency brake mounted in the hat of the rear rotor.
Tech Feature: Inspecting Shocks and Struts
Shocks and struts are simple devices. Their function is to dampen the movement of the springs, suspension and vehicle pitch. This means that as the spring is compressed, the movement is not sudden and when the energy or movement is released, it is not overpowering.
Tech Feature: Care and Feeding of Differentials
The lubricants that are used in manual transmissions, transaxles, differentials and transfer cases include a variety of different oils. Many transmissions, transaxles and transfer cases use gear oil with viscosities ranging from 75W-90 up to 85W-140. Others use ATF (Dexron II/III, Mercon V, etc.) or even motor oil (10W-30 or 10W-40). Most differentials, by comparison, use hypoid gear oils that also contain extra amounts of “extreme pressure” (EP) additives.
Diagnostic Solutions: Exhaust Restriction Diagnosis
To put exhaust restriction diagnostics in perspective, import specialist shops have been dealing with loss-of-power complaints caused by exhaust restriction since catalytic converters were popularly introduced in 1974. Early “cats” experienced frequent failure because the carbureted engines of that era were notorious for poor fuel control.
Diagnosing Common Pattern Failures on Mercedes-Benz Vehicles
Mercedes-Benz cars have long been associated with fine design and manufacturing quality. The proof for me is its use as hired transportation (taxi and bus) in many Third World countries. But for the U.S. market, the addition of power accessories and electronics is much more prominent than in other parts of the world. A quick overview of the most common complaints and repair patterns points to electrical problems as a serious problem for many M-B models produced in the last 15 to 20 years.
Alignment & Suspension Specs: 2007-2011 Ford Edge/Lincoln MKX
In 2007, Ford introduced the Ford Edge and Lincoln MKX crossover vehicles. The vehicles are based on the CD3 platform that is used for the Fusion and other Ford vehicles. FWD and AWD models are on the streets, but the alignment procedures are the same.
Tech Tip: Gaskets from Different Eras Vary Quite a Bit from More Modern Vehicles
When selling engine gaskets, the modern parts professional is often faced with a dizzying array of gasket technologies. The difference in gasket technologies among a ’50s-model pickup truck, a ’60s-vintage, high-compression muscle car and a modern bi-metal or aluminum engine is often quite dramatic.
