Vacuum Lines and Hoses
A series of flexible tubing within a vehicle used to transport air, vapors, pressurized gas, and fluids within a system or across multiple systems.
The total distance in the gap between a cam and the top of the valve. Because the rocker arm is located between the cam and valve, this distance must be measured as the gap from the cam itself and a rocker arm pad to where the rocker arm is actuated by the cam lobe.
Valve Gear Type
The total number of camshafts present in an engine and their exact positioning relative to the valves. Gear types help distinguish engine types, and differing configurations can have various performance effects.
Valves Per Cylinder
The total number of valves – for both the intake system and exhaust – that are utilized within each engine cylinder. Every four stroke combustion engine requires a minimum of two valves in each cylinder: one for air and fuel intake and the other for exhaust. Other models may have more valves depending on their specifications.
Mirrors which are equipped on the backside of a vehicle’s sun visors and used to help drivers and passengers with personal grooming. They are a highly common feature present in most standard vehicle releases from manufacturers.
Variable Gear Ratio Steering Assembly
A mechanism within the steering system which converts steering wheel motion into the back-and-forth side motion of a lever connected to the steering linkage. This essential assembly component ensures accurate translation of steering wheel motion to the movement of wheels. Any type of malfunction in this unit may negatively affect the driver’s ability to control their vehicle.
Variable Valve Timing
A feature equipped in some engines which can dynamically change the timing, lift, or duration of the valve train while it is operating. Ongoing adjustments of the valve train can improve a vehicle’s total performance, fuel efficiency, and the amount of emissions being released into the environment.
Vehicle Identification Number
Otherwise known as the “VIN,” this unique numerical code is created and assigned to every vehicle produced by its manufacturer. The number distinguishes it from every other vehicle on the road today. No two vehicles have the same uniquely identifying VIN which allows for accurate distinguishing of every automobile. In most cases, the VIN is stamped directly onto a plate or sticker which is placed in various spots throughout a vehicle. Locations include the driver’s door jamb, inside the engine bay, and in the connecting point between the windshield and the dash on the driver’s side. It is often placed in multiple locations in case one VIN sticker or plate is removed or damaged. Additionally, in cases of fraud, alternative locations can verify the accurate VIN for the correct vehicle. Within the VIN’s readout, certain digits will denote various manufacturing attributes. These include the model year, its final assembly location, and the vehicle model. Additionally, current 17 digit VINs can provide immediate online access to a variety of records related to that exact vehicle. Accessible records may include current or previous ownership, service or maintenance history, and any reports of accidents or repairs. Several reporting agencies are available to provide a detailed report of a vehicle based on its VIN.
A designation of the build type of a vehicle class which provides the major characteristics that distinguish it from other classes. Size, appearance, and power capabilities are a few examples of attributes separating differing vehicle types. Common types include compact cars, midsize cars, sedans, pickup trucks, minivans, sports utility vehicles (SUVs), vans, station wagons, and other special purpose vehicles.
Seats which are equipped with small holes in the bottom to direct and ventilate air from the cabin upward through the seat. This creates a more comfortable seating installation for occupants – particularly during longer rides in warmer temperatures.
Video Game Input
Input plugs in the rear seating section of a vehicle where video games can be hooked into a vehicle’s video system. These can be RCA plugs, HDMI cables, or other inputs.
A display system equipped within various systems within a vehicle. While most automotive monitors use liquid crystal display (LCD) technology, other display types may also be present depending on the model. These screens are common in vehicle entertainment systems as well as navigation systems.
Video Remote Control
A wireless unit which utilizes radio frequencies or infrared technology to control the video system within a vehicle’s video entertainment system with functions like power, volume, source, and display adjustments.
A device used to produce a video signal which is then displayed on a vehicle’s entertainment system. Signals can come from multiple sources of media such as a DVD, hard drive, memory card, or other element.
