Getting the Most Out of Your Lifts
Lifts play an important role in the day-to-day operations of any automotive service facility. Some may even argue that a lift is a shop’s most valuable employee. After all, lifts never call in sick or go on vacation. However, one of the worst things a shop owner can do is fall into the trap of
Saab 5-Speed Tranny and Clutch Repair
When Saab first introduced the 9000-model lineup in 1986, the gearbox was mounted transversely in the car. It was designed in this way for effective cooling and to provide the shortest possible path for the power flow to the wheels. All Saab transmissions have five forward speeds and reverse – all of which are synchronized.
Toyota Chassis & Suspension
Toyota builds some of the most durable cars and trucks on the market. And, there are models for every segment of the population, from eco models that only exhaust drinkable water into the atmosphere, to large luxury models in the Lexus line. With that said, the fact is, there will still be components that can
OHC Engine Repairs and Service on Chrysler’s 3.5L V6
Chrysler’s 24-valve 3.5L single overhead cam V6 engine was introduced back in 1993 in their LH platform cars (Chrysler Concorde, Dodge Intrepid and Eagle Vision). Since then it has been used in a variety of Chrysler models. The 3.5L engine is an even-firing power plant with aluminum cylinder heads, a single camshaft in each cylinder
BMW Performance Upgrades
When you talk about performance cars, a list of several manufacturers comes to mind. Before the explosion of Asian-made mini rockets, you needed to go European, and specifically German, to get the latest in performance machines. BMW has been the performance marque of choice for several decades. While BMW makes it difficult to improve on
Smooth Sailing: Steering, Suspension & Ride Control Repair Opportunities
Original equipment chassis parts on late-model cars and trucks are supposedly engineered to go 150,000 miles or more. But is that 150,000 miles of highway driving on nice smooth roads or 150,000 miles of bumps, potholes and rough roads? The OEMs say it’s some of both. Nobody can predict exactly how long a chassis part
Carburetor Repairs & Recalibrations
As a follow-up to “Dusting Off Fuel System Fossils” in April’s edition of Underhood Service, I will share many driveability concerns and emissions failures that I’ve repaired by rebuilding, and sometimes modifying, certain carb circuits. But before diving into a carburetor rebuild or recalibration, be certain that you understand the system you’re working on, including
Nissan Engine Diagnostics
You don’t have to be an import specialist to know that Nissan cars and trucks have a good reputation for reliability and longevity. Nissan, under the Datsun name, was one of the first Japanese automakers to break into the U.S. market. They did it right, by establishing a strong dealer network and offering a quality
Ford Timing Belts & Chains
Timing belt and chain replacement is one service that isn’t going away any time soon. Most Ford engines with overhead cam timing belts have a recommended replacement interval of 60,000 miles to 120,000 miles depending on the application (see the chart on page 54). So if a customer is driving a vehicle that is more
Mass Air Flow Operation Strategy
When diagnosing hot-wire air flow meters (A/F meters) on Subarus and similarly equipped Asian vehicles, technicians may find that, while the meter passes all recommended test procedures, the engine exhibits driveability conditions associated with lean air/fuel mixture ratios. In these cases, it’s best to form a diagnostic strategy based on the relatively simple operating principles
