Diagnosing GM LT1 V8 Engines
The Chevrolet LT1 engine is the second-generation (Gen II) design of Chevy’s famous small block. The LT1 was fitted in Chevy’s Corvette, Camaro and Caprice/Impala SS. This engine also was used by Pontiac for the Firebird, by Buick for the Roadmaster and by Cadillac for the Fleetwood. The LT1 was first available on the Corvette
Volvo Unveils Two Hot New Concept Cars at the 2005 SEMA Show
The two exciting new concept cars from Volvo explore the opposite ends of the spectrum in terms of just how far vehicle design may be pushed. Painted a glittering Saffron color reminiscent of a desert sunset, the XC70 AT (All Terrain) takes the production Volvo XC70 crossover wagon to the off-road extreme. The T6 Roadster takes Volvo to the drag strip with its 1930s inspired body, wide tires and low beltline.

Tech Tip: Air Flow Sensors – Understanding Their Function and Potential Problems
Most of us remember the "good old days" when an engine’s air/fuel (a/f) ratio was controlled by a mechanically operated carburetor. Due to the inherent design limitations of mechanical systems, however, carburetors don’t respond efficiently to changes in barometric pressure, temperature and humidity.
Tech Tip: Water Pumps – Why They Fail and When to Replace Them
If you’ve wondered how much work a water pump must do, remember that only about 30 percent of the heat energy produced by combustion results in mechanical energy. That estimate, of course, is a mathematical comparison between the heat value of the gasoline going into the engine, and the heat value of the mechanical energy coming out of the engine. The remainder of combustion heat must then be dissipated into the atmosphere through the exhaust, lubrication and cooling systems.
Time for Sale
If you do not charge for diagnostic time to diagnosis undercar problems, you might as well put a sign on the door that says “ROB ME.” With the complexity of brakes, suspension and exhaust systems increasing every year with little chance of standardization, it is difficult to diagnosis these systems with just a visual inspection,

Piston Technology: To Power Today’s V8s
The performance piston business today is hot thanks to a strong racing market and the introduction of new OEM engine families such as Chevy’s LS1/LS6 V8s, Ford’s 4.6/5.4L V8s and Chrysler’s Hemi. Piston manufacturers are introducing new performance pistons for all of these applications as well as refining existing piston designs to reduce weight, and
Carley’s Corner: My Advice on Gas-Saving Gadgets
ely, these cars were introduced a few years too soon and were discontinued because of limited range (about 100 miles on a full charge), and the high cost of the batteries (GM’s cost was reportedly $500 for each battery, and each car held 18 batteries!). If GM were to re-introduce the EV1 today, buyers would
