Fahrenheit:
Thermometer on which the boiling point of water is 212 deg. and the freezing point is 32 deg. above zero. To convert from Fahrenheit to Celsius, subtract 32 then multiply the result by 5 and divide by 9. To convert from Celsius to Fahrenheit, multiply by 9, then divide by 5. Now add 32 to the result.

  1. To add a fairing to a body.
  2. A vehicle in restorable condition needing only minor work to get all components working
Fairing:
  1. A protective shell or enclosure at the front of a motorcycle which may house the headlights and signal lights. It is designed to improve the aerodynamic performance of the machine and/or provide rider comfort and protection from the elements. These range from simple Plexiglas® shields to complex, encompassing body panels.
  2. The plastic shield mounted on the front of a roof rack of a car or truck which is designed to reduce wind noise and improve fuel economy.

False neutral:
When you fail to engage gears and the transmission behaves as though it is in neutral, even though it is not
Family car:
A car suitable for transporting a family, usually a four-door sedan, hatchback, or station wagon. It is becoming more popular for families to obtain a minivan instead of a station wagon.
Fan:
fan
  1. A fan is a rotating device with curved blades like a propeller. The primary fan in a vehicle is generally located behind the radiator. Some electric fans may be placed in front of the radiator. It draws air through the radiator so that the coolant looses its heat through the fins of the radiator. It is especially needed when the vehicle is idling or moving slowly. When the vehicle moves quickly, there may be no need for the fan. In some cases, the fan is automatically disengaged. The fan may be driven by a fan belt driven by the engine, or by electricity independent of the engine itself.
  2. Other fans are located throughout the vehicle to push air from one location to another, especially for heating and ventilation.
  3. Radial or axial flow device used for moving or producing flow of gases.
  4. The pattern emitted by a paint spray gun.

Also See:
cooling fan
heater fan
radiator fan motor

Fan belt:
A flexible rubber belt that connects various components in the engine compartment, i.e., alternator, water pump, emission controls, power steering pump, air conditioner compressor.
Fan blade:
A part of the fan projecting at an angle from the central hub, which draws the air through the radiator
Fan clutch:
A viscous (fluid) drive coupling device connected to the center of the fan to permit variable engine fan speeds in relation to engine speeds. The clutch engages and disengages the fan according to the engine temperature through a thermostat
Fan cooling:
A type of air cooling where a blower is responsible for transporting the amount of air required for the cooling of the engine past the cooling fins, which in turn dissipate the heat stored in them to the current of air flowing past them
Fan motor:
See:
radiator fan motor
Fanning:
The use of air pressure through a spray gun to speed up the drying of primer or paint—this is not recommended
Fan pulley:
A pulley on the hub of the radiator fan on which its driving belt runs

Fastback:

Fastback A design of car where the roof gently slopes to the rear end of the car. Any automobile with a long, moderately curving, downward slope to the rear of the roof. This body style relates to an interest in streamlining and aerodynamics and has gone in and out of fashion at various times. Some (Mustangs for one) have grown quite popular. Others have tended to turn customers off. Certain fastbacks are, technically, two-door sedans or pillared coupes. Four-door fastbacks have also been produced. Many of these (such as Buick's late 1970s four-door Century sedan) lacked sales appeal. Fastbacks may or may not have a rear-opening hatch.
Also See:

Also See:

Fatigue limit:
The maximum stress that a material can endure for aninfinite number of stress cycles without breaking
Fatigue resistance:
The maximum stress that a material can endure for a given time without breaking
Fatigue strength:
The maximum stress that a material can endure for a given time without breaking
Fatigue test:
A test on a material to determine the range of stress it will stand without failing, by subjecting it to rapidly varying stresses to establish its fatigue limit
Fat load:
Trucker slang for "overload," carrying more weight than local state law allows as in "Better not be running at fat load, cause the coops are open and checking ground pressure this morning."
Fault:
A defect which is either inherent in the vehicle as built (manufacturing fault) or which occurs during running.
Also See:
intermittent fault

Fault codes:
See:
trouble codes
