ABS Diagnostic Equipment

Antilock brake systems run self-diagnostic tests when the vehicle is driven to check for faults. If a fault is detected, it will usually set a code and turn on the ABS warning light to alert the driver.

Internal Engine Repairs: Uncovering the Culprits That Cause Head Gaskets To Fail

The first symptoms of a failing head gasket are usually a slow loss of coolant with no visible leaks, engine overheating and/or a check engine light with cylinder misfire codes. Uncover the culprits and prevent comebacks by following repair procedures to the letter.

Installation Errors Increase Risk of Power Steering Pump Returns

Replacing a power steering pump is a fairly simple job on most vehicles. But if the installation is not done correctly, it may result in noisy operation, reduced power assist or no power assist at all, according to Mike Simon of Ixetic, a manufacturer of power steering pumps.

Indirect Tire Pressure Monitoring Systems: The TPMS System That Knows The Road.

Indirect Tire Pressure Monitoring Systems (TPMS) are ones that do not have air pressure sensors inside the tires. Rather, they detect a low tire by comparing relative wheel speeds via the Anti-lock Brake System (ABS) wheel speed sensors. When a tire loses air, its diameter decreases slightly.

Tech Feature: Servicing Ford’s 3.0L Engine

The 3.0L Duratec V6 was introduced in 1996 to replace the aging 3.8L V6 in the Ford Taurus and Mercury Sable. Unlike its conventional pushrod predecessor, the 3.0L V6 has dual overhead cams, four valves per cylinder and an aluminum block with cast-iron cylinder liners.

News Technologies For Safer Driving: Adaptive Lighting, Night Vision, Backup Cameras & Blind Spot Detection

the road ahead, but they have limitations. That’s where new technologies such as adaptive lighting and night vision come into play.

Tech Feature: Oil Pump Technology

Oil pressure is something every engine builder worries about. Low oil pressure or a loss of pressure can cause expensive warranty problems and catastrophic engine failures, neither of which is good for your business. Though the “bigger is better” mentality persists, most engines only need about 10 psi of oil pressure for every 1,000 rpm of engine speed.

Tech Feature: Cooler ‘Heads’ Prevail – Pouring Over GM’s LT1 Engine and Reverse-Flow Technology

The LT1 engine was used in a variety of General Motors models, including 1992-’96 Corvette (Y-body), 1993-’97 Camaro and Firebird (F-body), and 1994-’96 Chevy Caprice and Impala (B-body), Buick Roadmaster and Cadillac Fleetwood (D-body).

Tech Feature: 2010 Camaro Has Power To Spare

Recently, I had an opportunity to drive both the 3.6L DOHC V6 and the 6.2L V8 versions at a press event held at Road America race track in Elkhart Lake, WI. The first Camaro I drove on the track felt really strong and I assumed it was the V8. So, I was rather surprised when I opened the hood and found a V6 sitting under the plastic trim cover.

Active Safety Technology: Adaptive Cruise Control, Lane Departure Warning & Collision Mitigation Braking

A vehicle that stops itself may sound like something out of a futuristic sci-fi movie, but the technology is here and now. From collision mitigation braking to adaptive cruise control, find out how many of today’s next generation active safety systems come into play.

Carley’s Corner: Changing Automotive Technology Makes ‘Right To Repair’ Act a Must for Independent Repair Shops To Survive

The past few years have seen rapid change in automotive technology. More and more hybrid models are being introduced, with nearly 1.5 million already being sold to date. Direct gasoline fuel injection is replacing port fuel injection on more and more engines. Many late-model engines are also equipped with variable valve timing (VVT) to improve

Automotive Fluid Exchange Equipment

Vital fluids – including engine oil, coolant, transmission fluid, gear oil, power steering fluid and brake fluid – need to be replaced periodically. Technical Editor Larry Carley discusses the equipment and tools necessary for the preventive maintenance essentials.
