Tech Feature: Hemisphere Exploration – Journey to the Center of the 5.7L Hemi
The 5.7L HEMI Magnum V8, which made its debut in 2003 in Dodge Ram 2500/3500 series trucks, was quite an improvement over the older 5.9L V8 it replaced. The engine was 56 lbs. lighter, produced 41% more horsepower and 12% more torque than the previous motor. Better yet, it also delivered 8-10% better fuel economy.
Tech Feature: The Variables of Valve Timing

Battery Service & Diagnosis
A good battery with an adequate charge is absolutely essential for reliable cold starting. A weak battery or one that is run down may not deliver enough amps to crank the engine when temperatures plunge and the oil thickens. Cold weather can be hard on batteries, but so can hot weather because it increases water

Tech Tip: Servicing Dual-Mass Flywheels
A dual-mass flywheel is essentially two flywheels in one that provides some spring cushioning to dampen torsional crankshaft vibrations and shock loading when the clutch is engaged. Think of it as a flywheel with some "give."
Servicing Solutions: In the Clutch…Servicing Dual-Mass Flywheels
A dual-mass flywheel is essentially two flywheels in one that provides some spring cushioning to dampen torsional crankshaft vibrations and shock loading when the clutch is engaged. Think of it as a flywheel with some “give.” The two-piece assembly has a front “primary” flywheel and a rear “secondary” flywheel. The primary flywheel bolts to the

Down the Road: Advances in Engine Technology
Two engine technologies that have been around for years are generating plenty of interest these days as the automakers look to create better fuel efficiency, without sacrificing power — direct injection for gasoline engines and turbocharging. Direct injection for gasoline engines is where fuel is injected right into the combustion chamber of each cylinder, as
