Hyundai Turbocharged Theta And Gamma Engines
Hyundai has two four-cylinder engines that use a turbocharger. The Gamma and Theta turbocharged engines were introduced in 2010 for many Hyundai cars and trucks. These engines also have direct injection, which makes them even more efficient.
Top EVAP Tips When Replacing Fuel Pumps
Nothing is worse than an EVAP code after a fuel pump has been replaced. Discovering that the tank needs to be dropped again to address a problem can kill shop productivity and profitability. The following tips can help you avoid comebacks and having to drop the fuel tank for a second time.
Diagnostic Solutions: How Electric Power Steering Systems Are Changing Undercar Service
Electric power steering contains a steering wheel position sensor and a steering input torque sensor. The data from these two sensors report to an EPS module, which translates the steering input torque into an appropriate level of steering assist via a pulse-modulated, bi-directional electric motor that’s connected to the steer gear input shaft or integrated into the steering rack assembly. The steering position sensor should read “zero” when the vehicle is traveling straight ahead.
Emerging Technologies: Are You Ready For ADAS?
While the term “ADAS” might not be familiar to you, you may better know the technology as automatic emergency braking and lane departure warning. Familiarize yourself with the ADAS features that are specific to the vehicles on which you’re working. Industry experts say that the complexity of these systems is only going to increase, so make sure you are ready to service and repair them, says Mary DellaValle, editor of ImportCar magazine.
BMW Tech Tip: Windshield Washer Jets Spray Little To No Fluid
If the window washer fluid jets spray a very low volume of fluid or no fluid at all, there are three possible causes.
Infiniti Tech Tip: Cruise Control Will Not Set And DTC P0605 Is Set
Improper adjustment or operation of the ASCD brake switch can cause the Automatic Speed Control Device (ASCD) to “not set” and/or DTC P0605 (ECM) to store. If a malfunction in the ASCD system is detected, the CRUISE indicator may stay ON and the “SET” indicator may flash.
Hyundai Tech Tip: Engine Vibration Due To Misaligned Timing Marks On The Oil Pump
This bulletin provides information regarding the proper indexing of the timing marks of the Oil Pump Module during in-vehicle installation, specifically on vehicles equipped with Theta four-cylinder engines.
Diagnosing Active Motor Mounts On Asian Vehicles
Many automakers, including Toyota and Honda, have changed their lineup of engines to improve fuel economy and emissions. Gone are the high-revving 1.8L and 2.0L four-cylinder engines. Replacing them are engines with displacements ranging from 2.3L to 2.5L. These engines are more efficient and produce more power lower in the power band. But, these new engines increase the stroke and not the bore, making for some unique vibration conditions the motor mounts have to minimize.
Diagnostic Solutions: Using The ‘Systems’ Approach To Starting Problems
Good examples of systems logic occur each September when I serve as a technical advisor for a church-sponsored single mom’s car care clinic. We sometimes, for example, accidentally bump hidden cranking “disable” switches installed by suspicious ex-husbands or encounter engines with bad fuel pumps that will start only by spraying a liberal dose of starting fluid into the air intake.
Wheel Bearing Technology: Don’t Become Complacent
I know some of you think the wheel bearing replacement does not merit an article, but this attitude can cause a comeback for late-model European vehicles. Wheel bearings are changing because the vehicles they are attached to and the brake rotors located on the other side are evolving. This has changed the designs and specifications for most bearings.
Inspecting Brake Hoses With Your Hands Helps Prevent Failure
A proper brake hose inspection should include checking all hoses for cuts, cracking or swelling. Brake hoses often crack around the metal sleeve that seals the hose to the metal fitting, so be sure to pay close attention to these areas.
Land Rover Air Ride Diagnostics
The air ride suspension on Land Rover Range Rover and Discovery models is what helps set these vehicles apart from a normal SUV. The system lifts the suspension up over obstacles, and lowers the suspension to make it easier for the occupants to get in and out. But with functionality, comes complexity.
