Valvetrain Controls: Are they phasing you?

New Valvetrain Timing and Control Systems Training Course Now Available When designing new engines today, engineers strive to improve fuel economy, power and emissions in many different ways. New technology and computer control systems have enabled engines to gain power and efficiency. Proper diagnosis requires understanding how these systems operate together. The new Instructor-Led Training (ILT) course, Valvetrain Controls: Are they phasing you? (S-EM01-01.01ILT) covers valvetrain timing and control systems on a variety of modern engines. The course covers: • Variable valve timing systems • Variable valve lift systems • Multi-displacement engine systems

losses by using intake valve lift to better match the amount of air entering the cylinders to the engine’s specific realtime load requirements. The control system switches between low and high valve lift, depending on needed engine output. The engine operates in low-lift mode when full power is not required and in high-lift mode when full power is required. In the course, the various manufacturers using this system are reviewed along with the differences in their engine components and operating parameters, including the GM 2.5L Ecotec, Toyota VVTL-i, Subaru i-AVLS, Honda VTEC, Audi AVL, Porsche VarioCam Plus, and Mitsubishi MIVEC.

Displacement on Demand

which offers lower emissions and increased power and efficiency. Several automakers currently offer CVVL-equipped engines: BMW (Valvetronic), Fiat (Multi-Air), Nissan (VVEL) and Toyota (Valvematic).

Displacement on Demand (DOD) is a system designed to shut down cylinders during light load conditions to improve fuel economy. The systems covered in the course include Active Fuel Management (GM), Multiple Displacement system (Chrysler), Active Cylinder Control (Mercedes) and Variable Cylinder Management (Honda).

Diagnostic Strategy Participants in the course will be presented with a iagnostic strategy for a number of valvetrain control condid tions. These include compression testing, vacuum gauge tests, cylinder leakage, and using an oscilloscope for engine mechanical faults.

The course covers operation and diagnosis of these systems, explaining that most of the cylinder deactivation systems use oil pressure to perform the changeover. If Diagnostic Trouble Code (DTC) diagnosis calls for performing oil pressure tests, then it is likely that something mechanical is causing the concern. Use a scan tool and oil pressure diagnostics to identify the mechanical fault, such as a solenoid or actuator element.

Variable Valve Timing

The case studies reviewed in the course cover several valvetrain control repairs. One Vacuum gauge attached to the intake manifold case study takes an in-depth look at the timing belt replacement on a Chevrolet Aveo with a 1.6L engine. Another case study covers an intermittently failing rocker arm oil pressure switch on a Honda Accord with a 2.4L engine.

Variable Valve Timing (VVT) alters the relationship between the camshaft and the crankshaft in order to optimize valve timing. The course covers how Camshaft end play VVT is used to enhance engine performance to smooth idle, increase horsepower, improve torque and regulate emissions, all while using fewer components.

Additional case studies include a Chevrolet Tahoe with the 5.3L engine that requires cylinder deactivation valve lifter manifold testing and a GMC Acadia with the 3.6L engine that needs to have the camshaft engine play on both camshafts checked based on the number of DTCs set.

VVT actuators serve to vary the camshaft timing in relation to the crankshaft. VVT actuator designs are varied. VVT actuator design may be helical-gear, vane type (both internal and external oil control valve designs) or chain adjuster. The actuators can be used on any engine valvetrain layout.

Buying a Laptop Computer? Computer Hardware Recommendations Technicians looking to work more efficiently may consider buying a laptop (or notebook) computer for use in the service bay. With their mobility, laptop computers make it easier to perform diagnostics and reduce the time away from the vehicle at a desktop PC. Before purchasing a computer for use with various service applications, it’s a good idea to review the GM IT Guidelines to ensure that the computer meets or exceeds the minimum specifications for running all ACDelco service applications, such as TIS2Web, GM Service Information and other software. The GM Dealership Infrastructure Guidelines – Service Department can be accessed at www.gmdesolutions.com. The guidelines specify that the computer should include business grade hardware that meets or exceeds the minimum specification with Intel Processors and runs the Windows 7 Professional 32 bit or 64 bit operating system. Prior to purchasing a business grade laptop, review the guidelines for what is “supported and not supported” for ACDelco service applications. Consumer branded PCs, systems built by hand and/or home grade operating systems typically used for

multimedia or gaming purposes are not recommended. GM also does not support AMD processors. Extensive testing of consumer targeted computers and operating systems show they are not suitable for diagnosing vehicles using ACDelco software applications, which are considered business class and are intended to run on a business grade computer. ACDelco service applications, such as TIS2Web, GDS 2, MDI, Tech2Win, etc., are compatible with the Windows 7 Professional (32 and 64 bit) operating system. They are not compatible with Windows 8.x Professional.

Browser Support Internet Explorer 9 (IE 9) is the recommended and minimum browser for use with ACDelco service applications. Internet Explorer (IE) 8 or earlier versions are not supported. Other browsers, such as Firefox, Safari, Chrome, etc., as well as IE 10 and IE 11, are not approved by GM at this time. The ACDelco service applications have not been tested against the newest IE browser versions.

Tablets Only tablet devices with business grade hardware that have the hard drive and memory capacity to support all 4

ACDelco service applications are recommended. These tablets must have Intel i series processors and Windows 7 Professional operating systems. Currently, one tablet approved for use available through GM Dealer Equipment is the Sahara Slate PC with a 12.1-inch touch screen display. It runs the Windows 7 Professional operating system and has an Intel Core i7 vPro processor, offering full PC productivity with tablet mobility. This tablet has passed numerous tests to ensure it is fully compatible with all ACDelco service applications, including TIS2Web, GDS 2, Tech2Win, Service Information (SI), and SPS. Non-business grade tablets, such as the Apple iPad, Samsung Galaxy and Acer Iconia, which are geared toward consumer use, are not suitable for ACDelco service applications. Often, these tablets may be used in the service bay for viewing the Service Information application. While these tablets can view web pages, they do not have TIFF or CGM plug-in support to view the Service Information graphics in an enhanced mode. Alternative operating systems to Windows, such as iOS (Apple), Android and Nexxus, are not supported by the ACDelco service applications. – Thanks to Bob Stewart

GM J-2534 Programming Tools More and more repairs in today’s vehicles require electronic control modules — everything from Engine Control Modules and Body Control Modules to door modules and others — to be replaced or have the software updated. Many of these control modules require programming or setup to function properly once installed. ACDelco provides access to the s oftware needed to perform module programming and setup for GM vehicles with a variety of subscription options available depending on the shop’s needs. Control module programming requires a J-2534 device (the SAE standard for communications between a computer and a vehicle) to connect the vehicle to a computer with the manufacturer’s programming software application.

In addition to the J-2534 GM Multiple Diagnostic Interface (MDI), ACDelco distributors and Drew Technologies offer three devices that specifically cover GM vehicles: the Mongoose Pro GM, CarDAQ-M and CarDAQ-Plus. The Mongoose Pro GM is a more economical option for shops new to module reprogramming. It is designed specifically for GM models only. The CarDAQ-M and CarDAQ-Plus are designed for programming all makes. The CarDAQ-Plus offers module programming along with diagnostic functions, key programming and data monitoring capabilities. The CarDAQ-M is a modular tool that can be upgraded with new modules to keep the tool up to date with the latest automotive repair technology.

ACDelco 95RPS Battery Acid Level Indicator Volkswagen, Audi and BMW models The ACDelco 95RPS Professional battery has an Acid Level Indicator that looks similar to a hydrometer on the top label of the battery. Unlike a hydrometer, the Acid Level Indicator will never turn green, no matter how much the battery is charged.

The engine oil pan drain plug looks like a banjo bolt, but acts more like a valve. This type of drain plug does not have to be removed to drain the oil. Just unscrew it a few turns and the oil will flow out of the holes in the bolt. Do not remove the engine oil pan drain plug when changing the engine oil. Removing the engine oil pan drain plug completely will result in the engine oil pan drain plug gasket becoming dislodged or lost.

Stop Lamp and Turn Signal Lamp Options 2009-2014 Chevrolet Express and GMC Savana cutaway vans There may be some confusion regarding the proper peration of the stop and/or turn signals on the cutaway van o models. This may lead to difficultly diagnosing a stop and/or turn signal condition. The BCM can be calibrated for Separated Stop/Turn Signal Circuits, RPO V4D.

The label states the Acid Level Indicator should be black.

The Acid Level Indicator will be black if the electrolyte is at the proper level or will be clear if the acid is at a low, unsafe level. If the Acid Level Indicator is clear, the battery has low lectrolyte and should not be used. Replace the battery e immediately. There is a statement on the top label explaining the Acid Level Indicator.

Turbo Diesel Engine Oil Drain Plug 2014 Chevrolet Cruze equipped with diesel engine (RPO LUZ) When performing an engine oil/filter change, it is critical that the diesel engine is not overfilled. Including the oil filter, the engine oil capacity is 4.75 quarts (4.5 liters) of oil. If the diesel Partially unscrew the engine oil drain engine is overfilled, plug to drain the oil. the engine can continue to run when turned off by using the additional oil as fuel, resulting in internal engine and exhaust system damage.

Without RPO V4D, the stop and turn signals are one lamp (same bulb). Traditionally, there will be one red stop/turn signal lamp per side. Circuit 618 Yellow (X405 terminal D) is for the left stop and turn signal. Circuit 619 Dk Green (X405 terminal E) is for the right stop and turn signal. With RPO V4D, the stop and turn signals are separate lamps (two different bulbs). Traditionally, there will be one red stop lamp and one amber turn signal lamp per side. RPO V4D is included with the Ambulance Package (RPO YF2), School Bus Package (RPO B3D) and Shuttle Bus Package (RPO ANC). Circuit 618 Yellow (X405 terminal D) is for the left turn signal only. Circuit 619 Dk Green (X405 terminal E) is for the right turn signal only.

Back to Glory NHRA Pro Stock Dragster Restored by former ACDelco Service Center Owner and local ACDelco Distributor

Over the years, ACDelco has ponsored a number of race cars in s the NHRA and NASCAR racing circuits. Recently, Ray Noreika, owner of Big Boyz Toy Box in Paterson, N.J., came across what appeared to be an ACDelco-sponsored NHRA Pro Stock dragster. He decided to do what any automotive enthusiast would do and restore it to its former glory. Noreika began turning wrenches at a local gas station at the age of 14. He later bought the station, where he sold ACDelco products for many years. He currently leases indoor and outdoor vehicle storage areas. Several years ago, when a lease expired and the owners never responded to renew the lease, he ended up with possession and, subsequently, ownership of two trailers. Inside, he discovered a damaged and disassembled NHRA Pro Stock dragster. The body was a Chevy Cavalier with no associated markings. The frame tag, however, showed that it was built by Jerry Haas. The parachutes also displayed the ACDelco logo and colors.

Two of a Kind A little research showed that ACDelco sponsored Kurt Johnson as a Pro Stock driver in the NHRA circuit. This dragster was one of two ACDelco Chevy Cavaliers built by Jerry Haas Race Cars in Fenton, Missouri, in 2000. Noreika decided to rebuild the dragster to its original design to p reserve a piece of drag racing history. He contacted ACDelco about the restoration and received permission to use its name, logos and paint c olors. Noreika, a former Oldsmobile Master Technician, showed the disassembled racer to Jerry Thomas, account manager for Tonsa Automotive (an ACDelco Distributor in New York and New Jersey). When Leon Bobelian, president of Tonsa Automotive, learned of the restoration plans, he offered the support of his company.

ST-PU-0005-14

Built for Speed Noreika totally disassembled the dragster and rebuilt the vehicle to meet the current NHRA chassis and safety regulations. The original v ehicle was registered for the NHRA Pro Stock Class, but Noreika would rebuild the car to participate in the NHRA’s Top Sportsman Class. He completely rebuilt the engine that was found in the trailer: a 598 cu. in. DART M Block with DART Big Chief Heads. The carburetor, a 1200 C.F.M. Holly 4BBL, was installed and flow tested to match the current demands of the engine. The engine was dyno tested with C14 race fuel at 1,005 HP at 7,100 RPM. The 5-speed manual G force transmission found with the car was replaced with a 2-speed Powerglide transmission. An MSD Grid Computer System was installed to monitor and control the performance of the car.

Noreika still had plenty of work ahead of him. The carbon fiber body had over 200 damaged areas that required painstaking repairs. Plus, the rear wheels were missing and a set of the original

There were also several other parts that had to be fabricated in Noreika’s machine shop. The outside professional vendors that spent many hours helping Noreika in the restoration process were eager to use their skills to bring the dragster back to its o riginal condition.

Ready to Race When the restoration was finally nished, the chassis received its NHRA fi 6.0 chassis certification. Now, Noreika is currently in the process of renewing his NHRA driver’s license so he can drive the car for his enjoyment during the 2015 NHRA and IHRA seasons at a few of the Northeast racetracks. rear wheels couldn’t be found. Noreika had a stroke of luck when he had a conversation with a business associate in New York who told him that he had the other Haas-built ACDelco Cavalier. The dragster was in pieces, but those pieces included the original rear wheels.
