Glossary “visual inspection” Definition:
Inspection by sight as opposed to smell, hearing, touch, or instrumentation.
v
visual weld inspection
Glossary “visual weld inspection” Definition:
Most practical method of inspection on a repaired vehicel, because the weld is not taken apart. It involves looking at the weld for flaws, proper size and proper shape.
viscous converter clutch (VCC)
Glossary “viscous converter clutch (VCC)” Definition:
Torque converter clutch that uses a silicone fluid to transfer and multiply torque, the silicon absorbs shock and dampens engine vibration during clutch application.
vise
Glossary “vise” Definition:
A device used to secure or hold parts during hammering, cutting, drilling and pressing operations. It is normally bolted to a workbench.
vise caps
Glossary “vise caps” Definition:
Soft metal or plastic vise jaw covers that will protect a part from being marred by the jaws of the vise.
viscous friction
Glossary “viscous friction” Definition:
Friction between layers of a liquid.
viscous drive fan clutch
Glossary “viscous drive fan clutch” Definition:
Belt driven, water-pump mounted, liquid-filled or thermostatically controlled cooling fan clutch that drives the fan fast at high temperatures and slow at low temperatures.
viscous
Glossary “viscous” Definition:
1). Thick. 2). Tendency to resist flowing.
viscous coupling
Glossary “viscous coupling” Definition:
Coupling device having input and output shafts fitted with thin, alternating discs in a closed chamber filled with a viscous fluid.
viscous damper
Glossary “viscous damper” Definition:
Type of crankshaft harmonic balancer that contains a liquid to control engine vibration.
viscous fan
Glossary “viscous fan” Definition:
Cooling fan attached to a viscous coupling.
viscosity cup seconds
Glossary “viscosity cup seconds” Definition:
Number of seconds paint should take to flow out of a viscosity cup, if thinned or reduced properly.
viscosity grade
Glossary “viscosity grade” Definition:
Numerical rating of a fluid’s resistance to flow, as rated by SAE.
viscosity index
Glossary “viscosity index” Definition:
Number to indicate the change in viscosity of an oil when heated.
viscosity index improvers (VI)
Glossary “viscosity index improvers (VI)” Definition:
Chemical compounds added to engine oil to help the oil resist thinning at high temperatures.
viscosity rating
Glossary “viscosity rating” Definition:
Numerical indicator of the viscosity of an engine oil established by SAE.
viscosity cup
Glossary “viscosity cup” Definition:
Device used to measure the thickness or fluidity of the mixed materials, usually paint. It is a small stainless steel cup attached to a handle.
VIS
Glossary “VIS” Definition:
Vacuum Input Switch
viscose friction
Glossary “viscose friction” Definition:
Friction between moving parts, such as in a manual transmission, resulting from using an lubricate that is too heavy or thick.
viscosity
Glossary “viscosity” Definition:
Resistance of a fluid to flowing. Measurement of how easily a liquid can flow.
