Foreign Affairs: Servicing Secrets for the VR6
The Volkswagen VR6 engine has been around now for more than 10 years. And given its proven track record of reliability and durability, it’ll be around for years to come. Although not as popular (or as high in production) as its 4-cylinder brothers, we do see quite a few of these cars for regular maintenance,
Flushing Away Engine Problems
When motor oil isn’t changed often enough, varnish deposits and sludge begin to form inside the engine. If the oil is neglected long enough, it will eventually turn into goo and ruin the engine. “Oil sludging” has become a serious problem in recent years for a number of reasons. One is that more new car
Diagnosing Automatic Transmission Complaints
Automatic transmissions are a mystery to most motorists. They may know the transmission requires some kind of fluid, but have probably never checked the level or even looked for the dipstick unless they drive an older vehicle with a leaker. When internal problems cause the transmission to act up, it takes a fair amount of
Manual Tranny/Clutches: Pre-Installation Inspections Boost Clutch Performance & Reduce Warranty Claims
Because a good “stick shift” driver can always squeeze a few more miles per gallon out of a manual transmission or otherwise out-perform their automatic transmission counterparts, it’s no wonder that clutch replacements continue to be a good business for most import repair shops. In most cases, a routine clutch replacement requires very little in
Performing Hyundai Maintenance and Profiting From It
Like so many other late-model vehicles, the Hyundai vehicle lineup won’t necessarily keep your bays busy with “repair” work, but can present you with profitable maintenance opportunities. We can no longer afford to let any opportunity for service go unnoticed, and hope that the customer will come back for the next job. It’s an important
Caliper Science Friction
Disc brake calipers come in many sizes and configurations, including fixed-caliper, multi-piston designs, and the more modern floating-caliper, single piston designs that may also contain a mechanically actuated parking brake. Needless to say, disc brake calipers have undergone a series of design changes that continue to make them more adaptable to late-model vehicle applications. To
Drum Brakes, Understanding The Hydraulic Side
The wheel cylinder supplies the muscle for a drum brake. Most wheel cylinders are relatively simple: a pair of horizontally opposed pistons mounted inside a cast iron or aluminum housing. A brake line or hose from the master cylinder routes hydraulic pressure to the wheel cylinder, which pushes the pistons out. This forces the brake
Internal Engine Repairs: Begin with Diagnosing Engine Failure Culprits
Saab engine technology has evolved through the years, but the same basic design of the original B202 engine is still used in today’s Saabs. When the 16-valve 2.0L engine (B202) was developed in 1984, I was one of 10 people chosen from the East Coast area by Saab in the United States to attend a
Disc Brake Calipers

Timing Belt Replacement on a Sideways Engine
A timing belt failure can be a serious problem, not only because it strands the motorist, but also because of the extensive engine damage it can cause. If the engine is an “interference” application, a timing belt failure may result in bent valves, damaged pistons and a very expensive repair bill for your customer. For
