Park light The lights
on the corners of a vehicle, normally amber, that illuminate when
the headlight switch is partially activated (headlights off). Also
known as marker lights. |
Pickup Bed The open portion
of the pickup body, behind the cab, used for carrying large loads
that don't fit in the passenger compartment. |
Pickup Cap/Topper Normally
an aftermarket cover for a pickup bed, it provides a raised, covered,
lockable area for storage of easily damaged or pilferable cargo. |

Piston Pistons are the cylindrically
shaped parts inside the engine that provide for compression of the
fuel air mixture and removal of the exhaust gases. They move up and
down inside the engine as the engine runs. There are as many pistons
in an engine as there are cylinders. |
Power Steering Box The
power steering box is the actual steering mechanism on a vehicle with
power steering. It is a heavy metal case containing the steering gears,
and can be found under the hood, at the end of the steering shaft,
directly in front of the driver. |
Power Steering Control
Module The brain behind electrically operated power-assisted
steering systems. Very new, it is seeing limited usage but should
become more popular. The control module takes in sensor readings of
vehicle speed and steering wheel position and uses that information
to adjust the steering units rate of turn and force. |

Power Steering Control
Valve Is mounted at the end of the steering shaft under
that hood, and directs the flow of power steering fluid to the power
steering control unit in accordance with the position of the steering
wheel. |
Power Steering Pump Most
often located at the front of the engine and driven by a belt, the
power steering pump provides fluid under pressure to the power steering
box to assist in turning. |
|
Proportioning Valve
(Brake) The proportioning valve is normally located
in the vicinity of the master cylinder, and divides the brake fluid
pressure between the front and rear brakes to prevent rear wheel
skid. Front brakes always need more pressure than the rear brakes
due to the fact that the vehicle will "lean" forward under braking
conditions, which applies more weight to the front end and less to
the rear.
