The cast iron manifolds feature saw cuts along their cylinder head mounting flange, which split the flange into three separate sections on the V6 and four separate sections on the V8s, allowing each section to move under extreme hot-cold temperature fluctuations to virtually eliminate movement of the exhaust manifold gaskets. The lightweight valves enable the engine to rev quickly and capably to greater than 6,000 rpm. The heads features smaller combustion chambers shaped to complement the unique topography of the piston heads. Remove the 2 bolts running through trans, then remove the oil pan bolts had 12 in all. It also incorporates new engine mount attachments, new knock sensor locations, improved sealing and oil-spray piston cooling. Large, lightweight intake and exhaust valves are used in the aluminum alloy heads, including 1.
It supports tremendous airflow at higher rpm for a broad horsepower band, along with strong, low-rpm torque. The cuts virtually eliminate friction on and movement of the exhaust manifold gaskets, helping ensure proper sealing for the life of the engine and reducing the chance of gasket failure. Its dual-pressure control enables operation at a very efficient oil pressure at lower rpm, and then delivers higher pressure at higher engine speeds to provide a more robust lubrication. Lower the glove box door and remove the interior box. It is well above the full dimple and the entire cross hatch pattern. The smaller chamber size and dished pistons work together to produce an 11.
Thank you for your cooperation. A redesigned windage tray is also used with the Gen V engine, which features a new oil scraper design. To further enhance combustion, the intake and exhaust valve positions have been switched from previous versions, and the valves are now slightly canted toward the cylinder centerline. More than 100 iterations of the combustion systems were evaluated through computer modeling before a final design was selected for each engine variant. The engines also feature a new cylinder-head design and a new, sculpted piston to optimize the mixing of air and fuel in the engine and the burning of the mixture to create power.
This technology moves the point where fuel feeds into an engine closer to the point where it ignites, enabling greater combustion efficiency. But they still have a way of measuring it. The 2015 Silverado comes in seven distinct trim levels. This increased efficiency can now be maintained over a broader range of operating conditions. They also have a unique head topography that is essential to the direct injection system.
As an add-on feature, the Silverado is available with a trailer brake control and rear-vision camera. Direct Injection The new EcoTec3 engines use direct fuel injection, which precisely meters fuel directly into the cylinders, to optimize combustion over a broad range of conditions. Also, the spark plug angle has been revised and the electrode is now closer to the center of the chamber to support optimal combustion. A rugged, large displacement engine is well suited to reliably providing this power and torque, year in and year out. That helps ensure proper sealing for the life of the engine and reduces the chance of gasket failure. In addition to the new combustion chamber design, the Gen V head features large, straight and rectangular intake ports that feature a slight twist to enhance mixture motion.
The spark plug angle and depth have been modified to protrude farther into the chamber, placing the electrode closer to the center of the combustion to support the direct injection system. It also provides another effective tool for controlling exhaust emissions. Drain the oil and remove the filter; re install drain plug with new gasket. You get our best and most sophisticated technology regardless of trim level. SierraHarley: So lets gets this straight.
The 2015 Chevy Silverado is available with segment-exclusive safety features such as Forward Collision Alert, Lane Departure Warning with an Active Safety Seat and Front and Rear Park Assist. That allows the mixture to be leaner less fuel and more air , so less fuel is required to produce the equivalent horsepower of a conventional, port injection fuel system. I worry that the oil filter won't hold up for longer intervals. The deep-skirt block design helps maximize strength and minimize vibration. These lines become brittle with age and sometimes leak causing fuel to run down into the cra … nkcase. Remove black plugs on lower part of transmission, they hide 2 bolts. Let set for about 5 minutes or more- no more than 10 minutes depending on temperature outside curing time.
It is an engine-driven pump. An individual coil for each spark plug delivers maximum voltage and consistent spark density, with no variation between cylinders. It was refined and modified to accommodate the mounting of the engine-driven fuel pump and vacuum pump. Beneath the cabin, the Silverado features electric power steering and a revised front and rear suspension with wider wheels, for better handling and a more comfortable ride. A structural aluminum oil pan further stiffens the bottom of the block. Even the online 2015 manual states 8.
Thanks dlw1016a answered 3 years ago It should be listed in your owners manual under capacities I believe. Don't forget the battery connection and the oil --Roughly 2. Nodular caps are stronger and can better absorb vibrations and other harmonics to help produce smoother, quieter performance. The 2014 Silverado and 2014 Sierra make the most of the technology, with improved engine mounts, electronic throttle control, adaptive exhaust systems, improved aerodynamics, low-rolling resistance tires, and other technologies that help the engines operate in four-cylinder mode for longer periods of time, further increasing efficiency. It is best to wait until the truck has been sitting for about 15 minutes to get an accurate reading.
