Threaded fasteners require the proper amount of tightening in order to achieve the desired clamping force to secure components. This may involve either reaching a specified torque value or a combination of torque plus additional angle tightening. Either way, the goal is to obtain proper clamping load. With few exceptions, tightening by “feel” is simply inadequate. Under or over tightening can cause fastener failure, components cracking, allowing leaks of combustion pressure, vacuum or fluid leaks, warped components or any combination of faults. Adhering to published torque (or torque-plus-angle) specifications is important for all installation or assembly tasks, but is especially critical for engine, transmission, steering, suspension and brake system applications.
Ride control complaints are one of the most common types of concerns expressed by customers. Quite often, the customer’s description is vague or misleading. Attempt to gather as much information from them as possible prior to performing an inspection. For example, do you only hear a “funny” noise when driving n bumpy roads or on smooth roads as well? If you suspect that the vehicle is heavily loaded with cargo at times, ask if the “wandering” they experience only occurs when heavily loaded, etc. The customer’s descriptions of an issue should be considered merely as a starting point. It’s up to you to inspect and road test to determine the actual cause of the complaint.
How many times has someone told you to take care of your hearing? Anyone who works in a busy shop is subjected to a range of noises every day....pneumatic wrenches and impact guns, drills, air compressors turning on, vehicle horns, vehicle alarm system screeches, hammers striking metal, etc. Some of these noises, especially repeated exposure to certain noises, can damage your hearing. We all know how important it is to wear eye protection to save your eyeballs from fluids or metal chips, and to wear reinforced work shoes to save our toes from being mashed by heavy objects and gloves to protect our skin from certain chemicals or from handling hot and/or sharp objects, but many of us tend to ignore ear protection, often assuming that “the noise only lasts for a few seconds, so it won’t matter.”
Sioux Falls, S.D., is home to an array of historical, cultural and recreational attractions, with the impressive Big Sioux River and Chris’s Auto Repair LLC among the top of the list. This may sound a bit of an exaggeration at first, but Chris’s has gained quite a bit of notoriety since its beginnings a mere seven years ago.
“My engine blew a head gasket and now it overheats.” That’s a fairly commonly heard knee-jerk diagnosis. However, it’s wrong. When an engine overheats or if the gasket allows coolant or combustion gasses to escape, do not automatically blame the gasket. Cylinder head gaskets can be viewed similar to a fuse. If the gasket “fails,” this is a symptom that something other than the gasket itself caused the failure.
We’re all familiar with the “new normal” of social distancing to prevent the spread of a virus. While this concept applies to people, I wondered if we could equate this to vehicles. Yes, my mind does work in strange ways at times, and this is a prime example.
In our 10th installment of Techs Helping Techs, we have the opportunity to allow our readers to share valuable information, for the benefit of all.

Thanks to those who pitched in.
Every vehicle requires periodic maintenance (preventive maintenance) to avoid problems. The same holds true for certain tools and shop equipment. Lifts should be inspected annually, office and shop computers require updates, torque wrenches require periodic calibration, pneumatic tools require in-line lubrication to prevent dry running and lockups. Bay door rollers require cleaning and lube to keep them running smoothly.
While technological changes and advancements are in the works for future vehicles, such as electronic braking systems, we thought it best to discuss what’s happening at the current time, in terms of brake pad, rotor and fluid technology. Included in this article are comments from several brake system parts manufacturers.
There are tools that allow you get the job done, and there are tools that allow you get the job done quicker and/or more efficiently. In this brief article, we cherry-picked a few examples of items that help to make shop life easier, with less effort and that help to maximize labor profit.
Problem diagnosis of our occasional faulty memory can sometimes prove difficult, especially when the concern occurs on an intermittent basis. Sometimes, we just need to step back, take a deep breath and perform a step-by-step reprogram. Take the following example, wherein I misplaced a Torx T15 bit:
