Tech Tip: 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.
Toyota Engine Repair: Recurring Failures Flee with Proper Maintenance
Toyota’s 22R series 4-cylinder SOHC engine has survived and thrived in its cars and trucks for nearly 30 years, and is a desired powerplant for its power, torque and reliability. The basic design is a continuation of the engine that preceded it, the 20R, which was used in cars and trucks starting in early 1978.
Improving Diesel Technology
There is a “shade tree” law from the 1970s that states that computing capacity doubles every few years. In fact, computing capacity for the size of the computer or device has outstripped that by several orders of magnitude in the last five years. As evidence of that, we now see cell phones that were only
Sealing It Up Right: Proper Engine Bolt Use
How important are the various fasteners in an engine? Consider this: the head bolts have to withstand tremendous loads to keep the cylinder head sealed tightly against the head gasket and block. In an engine with 4” cylinder bores and peak combustion pressures of around 1,100 pounds per square inch, each cylinder exerts about 13,827
Carley’s Corner: Hybrid Hazards
Is E85 motor fuel a corny way to reduce American’s dependence on foreign oil? E85 is being touted as an eco-friendly, alternative fuel that can provide a home-grown solution to reducing our need for imported oil. E85 is a mixture of 85% ethanol alcohol and 15% gasoline. The alcohol is made primarily from corn, but
Tire Tech Tip: Right Size, Wrong Load Index Can Mean Liability Risk
When you sell a set of non-OE tires, do you set the air pressure the same as it was in the OE tires? Do your sales staff, manager and technicians understand the importance of load index? Can they read a load and inflation table? Can they recite, from memory, the inflation rule – that the replacement tire must meet or exceed the OE tire’s load-carrying capacity?
Alignment Equipment

We will look at different product categories and track the innovations that have shaped these products and the future for these segments. Alignment Retrospective In the
Tech Feature: Solving Intermittent Electrical Problems
Intermittent electrical faults are the bane of the auto repair business. If an electrical component has failed, or there is an open or a short in a circuit, you can usually find it fairly quickly because it isn’t hiding from you. It’s a persistent fault that can be isolated by a systematic process of elimination.
Directions: Positive Treatments to Our ‘Oil Addiction’
In his State of the Union address in late January, President Bush called for America to break its addiction to oil from the Middle East.
