Hyundai Fuel System And Emissions Diagnostics
We recently had a 2002 Elantra GLS in the shop with assorted issues, so let’s take a look at this job since it’s a good example of some common problems we see.
Water Pump Replacement: Nissan VQ-35 Series
At the top of the list of the most difficult water pumps to Âreplace are those found in the Nissan VQ-Series V6 engines.
Combustion Chamber Diagnosis
Diagnosing misfires and emission problems is getting more difficult on modern engines. Understanding what is going on inside the combustion chamber and what comes out the exhaust valve is critical to being able to solve any emissions or drivability problem.
10 Signs The Harmonic Dampener Has Failed Or Is Close To Failing
One sign is incorrect timing marks. If the outer ring has separated from the inner ring, the timing marks will move. This can been seen when comparing the timing marks on the valvetrain.
The All-New Ford EcoBlue Engine Is A Diesel Game-Changer
Ford has revealed the first new EcoBlue advanced diesel engine that will offer optimized fuel efficiency and reduced CO2 and NOX emissions for customers, using sophisticated technologies and innovative design.
Vacuum Power Assist Service
Most late-model vehicles use a vacuum booster to help apply the brakes. The booster is usually located behind the master cylinder on the firewall. A leak in the vent valve can cause a reduction in the performance of the booster and increase pedal travel. A manifold vacuum of 20 inHg or greater can be achieved during deceleration. The booster chambers can be evacuated and retained at this pressure by a properly operating check valve.
Brake Assist: Diagnosing Low And Hard Brake Pedals
Brake pedal assist complaints are often subjective in nature and, for that reason, can be difficult to solve. Grandma, with her arthritic feet, might be highly sensitive to a slight loss of pedal assist, but her lead-footed grandson not so much. But on-going technology is bringing a certain degree of objectivity into brake-assist diagnosis.
Hot Engines For Hot Wheels – The Reality Of Building Engines For TV
Richard Rawlings, owner of the Gas Monkey Garage in Dallas and host of “Fast N’ Loud,” was given the opportunity to build a replica 1968 Corvette to celebrate the Hot Wheels Sweet 16, the first series of toy cars produced by Mattel in 1968. He immediately had visions of a blown big block engine to power the classic, and he called on WCH Racing Engines in Midlothian, TX, to build it.
Chevrolet’s LT Engine Reboot
In 2014, GM brought back the highly recognized RPO code LT1. The reason for the comeback was due to more power and efficiency with fewer emissions. The new LT1 revision consists of a 6.2L (376 cu. in.) package weighing in at 465 lbs. delivering 450 hp and 450 ft.-lbs. of torque and offering 26 mpg. The new LT1 is more efficient, more powerful and offers more response than a smaller V8. Also, the new LT1 is faster than a twin-turbo V6.
Volkswagen’s 1.4L Engine Reinforces Turbocharged, Direct Injection Technology
Volkswagen pioneered the use of small displacement; highly efficient turbocharged and direct-injection engines in the U.S. Volkswagen first used this combination of turbocharging and direct injection in this market in its TDI Clean Diesel engines in the Passat in 1996 and extended it into the gasoline field in the 2006 Jetta GLI and GTI models.
