Hoisting & Jacking
This safety device must always be placed underneath a vehicle frame after lifting it with a hydraulic jack before working underneath.
What are jack stands?
These long, slender pliers are designed to reach into tight spaces and bend small wires or hold tiny clips.
What are needle-nose pliers?
The drive size of standard automotive ratchets (such as 1/4-inch, 3/8-inch, and 1/2-inch) refers to the dimensions of this square component.
What is the drive anvil (or square drive)?
To prevent internal vanes, in an air tool, from sticking and rusting, a few drops of this liquid should be added daily directly into the air tool's inlet.
What is pneumatic air tool oil?
This unique 17-character alphanumeric code acts as a vehicle's fingerprint and contains manufacturing details and specifications.
What is the VIN (Vehicle Identification Number)?
These designated reinforced areas along a vehicle's unibody or frame are designed to support weight without causing body damage.
What are lift points (or pinch welds)?
Commonly referred to by the brand name Vise-Grips, these pliers can be adjusted and clamped onto an object to hold it tightly without continuous hand pressure.
What are locking pliers?
To prevent rounding off fragile hex bolt heads, this type of socket offers maximum surface contact compared to a 12-point socket.
What is a 6-point socket?
Installed inline on shop air systems, this device removes water droplets and solid debris before the compressed air reaches the tool.
What is an air filter / water separator (or moisture trap)?
Because traditional glycol-based brake fluid readily absorbs water from the air, it is classified as having this property.
What is hygroscopic?
This mechanical safety device on a two-post lift automatically engages as the lift rises to prevent the vehicle from dropping if hydraulic pressure fails.
What is a safety latch (or mechanical lock)?
These adjustable pliers feature an angled head and an adjustable tongue-and-groove joint, making them ideal for gripping round pipes and large fittings.
What are channel-lock (or rib-joint, tongue-and-groove , water-pump) pliers?
This flexible socket attachment uses a swivel joint to allow ratchets and extensions to turn fasteners at an angle in cramped spaces.
What is a universal joint (or swivel adapter)?
This heavy-duty pneumatic tool delivers rapid rotational impacts and high torque to quickly loosen stubborn lug nuts and suspension bolts.
What is an impact wrench (or air gun)?
This internal engine component connects the crankshaft to the camshaft to ensure the valves open and close in sync with piston movement.
What is a timing belt (or timing chain / timing gears)?
Before fully elevating a vehicle on a frame-contact lift, you must raise it a few inches off the ground and perform this physical stability check.
What is a shake test (or bump test)?
Designed with small, pointed tips, these specialized pliers remove or install internal and external retaining rings on shafts or inside bores.
What are snap-ring (or retaining ring) pliers?
These dark, thick-walled sockets are made from ductile chrome molybdenum steel to withstand sudden high-torque impacts without shattering.
What are impact sockets?
Standard shop air pressure for operating most automotive pneumatic tools typically ranges between these two PSI values.
What is 90 to 120 PSI?
According to Ohm's Law, this unit measures the electrical resistance within a circuit or component.
What is the Ohm?
Hydraulic floor jacks operate on this physical law, which states that pressure applied to an enclosed fluid is transmitted equally in all directions.
What is Pascal's Law?
These heavy-duty cutting pliers have angled jaws designed specifically for cutting wire, zip ties, and small cotter pins flush against a surface.
What are diagonal cutters (or dikes)?
This precision tool is used to tighten fasteners to an exact manufacturer-specified tightness, measured in foot-pounds or Newton-meters.
What is a torque wrench?
This high-RPM pneumatic tool accepts carbide burrs or grinding stones to clean gasket surfaces, deburr metal edges, or enlarge holes.
What is a die grinder?
A fully charged 12-volt automotive lead-acid battery consists of six cells connected in series, with each cell producing approximately this many volts.
What is 2.1 volts (for a total rest voltage of roughly 12.6V)?
