HYDRAULIC CONTROL VALVE - Directs hydraulic fluid to provide required pressure to actuate
and deactuate fan clutch as required by engine temperature. Hydraulic pressure is supplied by power
steering pump.
HYDRO-BOOSTER - Converts hydraulic power from the steering pump to mechanical power to
the master cylinder, providing power assist during braking.
POWER STEERING COOLER - Is part of oil cooler which directs power steering fluid through a
series of fins or baffles so outside air can dissipate excess heat before the fluid is recirculated through
the steering system.
SERPENTINE BELT - Transmits mechanical driving power from crankshaft drive pulley to
steering pump pulley which drives the steering pump.
OIL RESERVOIR AND STEERING PUMP - Combined in one unit, the reservoir serves as an oil
filling point and the pump supplies the oil under pressure throughout the steering system.
FAN CLUTCH - Hydraulically-actuated by pressure from hydraulic control valve to control
operation of fan. Hydraulic pressure is supplied by power steering pump.
