Kingwood Park High School Already Turning Out Platinum Grads Of New I-CAR Curriculum
Twenty-three of his students completed the Into Series within four weeks and are on track to earn Platinum by no later than March 2017.
Direct Injection And Carbon Deposits
In 1985, Saab began using the new Bosch LH fuel injection system, and Volvo and other carmakers followed suit. The system worked such that incoming air passed through an airflow meter that sent a signal to the engine ECU telling it how much air was going into the engine. The coolant temp sensor then told the ECU how cold or warm the Âengine was, and it opened and closed the injectors when needed.
Power Steering Hoses: Inspection And Repair
The life of power steering hoses is not easy. Power steering hoses must endure some of the highest pressures and temperatures under the hood. Coupled with ozone, oil and solvents attacking the outer layers of these power steering hoses, it is easy to see why some hoses fail.
BMW Fuel System Repair Essentials
The BMW N54 fuel pump recall a few years ago brought to light the importance of the integrity of the fuel system and how it can contribute to the overall reliability of a vehicle. While BMW never officially stated what was causing the high-pressure fuel pumps to fail, some put the blame on low-quality fuel that might have been contaminated or had higher-than-normal Âlevels of ethanol.
Audi Direct-Injection Issues & Carbon Deposits
In 2006, we saw the first of the direct-injection cars. VW and Audi located the injectors directly into the combustion chambers for greater efficiency. By this time, we had been seeing variable valve timing for at least six years, and there were a few cars that had variable intake runners. The new A4s and Passats had both and, in addition to the in-tank fuel pump, they had a cam-driven, Âmechanical high-pressure fuel pump that ran the fuel pressure as high as 120 bar. They are great cars, but began to exhibit a few problems that we started to see after a few years.
Proper Coolant Selection Prevents System Degradation
Coolant is easily analogized to blood, both being liquids that are essential to the functioning of an entire complex system. The analogy extends even Âfurther though because, like blood, coolant has different types, and it’s not a stretch these days to say that swapping an OAT with an HOAT, or vice versa, is on the level of transfusing Type A blood with Type B.
Automotive Repair Shops Urged to Nominate Schools for 2010 SOTY Contest
Giving Some ‘Extra Credit’ to Deserving Schools by Ed Sunkin, Editor, Underhood Service magazine The automotive aftermarket is of vital importance to our nation. The future of our survival depends on those being trained to service vehicles. Not just the cars on the road today, but the pre-OBD vehicles of the past, as well as the high-tech

Undercover: Subcompact Vehicle Upgrades — A Reduction in ‘Class Size’
Over the next decade, it would appear that we will see a shift to smaller, lighter and more fuel-efficient vehicles, much like we experienced in the 1970s.
Finish Line: Hosting a Car Care Inspection Event at Your School
An event at your school could be used as a fund-raiser, as donations from vehicle owners who participate in the vehicle inspection process can be used for automotive lab and classroom equipment.
