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 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 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
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 rating
Glossary “viscosity rating” Definition:
Numerical indicator of the viscosity of an engine oil established by SAE.
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 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.
