COOLING SYSTEM
1. GENERAL DESCRIPTION
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. When the engine is cold, the cooling system cools the engine slowly o
r
not at all. This slow cooling of the engine allows the engine to warm up quickly. The cooling
system includes a radiator and recovery subsystem, cooling fans, a thermostat and housing, a
water pump, and a water pump drive belt. The timing belt drives the water pump.
All
components must function properly for the cooling system to operation. The water pump draws
the coolant from the radiator.
The coolant then circulates through water jackets in the engine block, the intake manifold, and
the cylinder head. When the coolant reaches the operating temperature of the thermostat, the
thermostat opens. The coolant then goes back to the radiator where it cools. This system
directs some coolant through the hoses to the heat core. This provides for heating and
defrosting. The coolant reservoir is connected to the radiator to recover the coolant displaced
by expansion from the high temperatures. The coolant reservoir maintains the correct coolant
level. The cooling system for this vehicle has no radiator cap or filler neck. The coolant is
added to the cooling system through the coolant reservoir.

POWER STEERING SYSTEM

4. OVERVIEW
The power steering system consists of pump, oil reservoir, rack and pinion gear. The power
steering pump is a vane type and delivers hydraulic pressure to operate the power steering
system. The pressure relief valve in pump controls the discharging pressure.
The rotary valve in rack and pinion gear directs the oil from the power steering pump to one
side of rack piston.
The integrated rack piston converts the hydraulic pressure to linear movement.
The operating force of rack moves the wheels through tie rod, tie rod end and steering knuckle.
Even though the hydraulic pressure cannot be generated, a driver can steer the vehicle without
power assist but it needs very high steering force.
In this case, the operating force of steering wheel is conveyed to pinion, and the movement o
f
pinion moves the rack through pinion gear combined to rack gear.

POWER STEERING SYSTEM
3. POWER STEERING PUMP
The vane type pump that is connected to engine by belt is used for the power steering system.
This pump generates and controls a proper hydraulic pressure and flows by using the flow
control valve and pressure relief valve.
The flow control valve regulates the excessive amount of discharging oil. When the steering
wheel is stationary or the oil circuit is blocked, the pressure relief valve returns the ove
r
pressurized oil to the oil reservoir.
4. OIL RESERVOIR
The oil reservoir sends the oil to the power steering pump and receives the oil from the power
steering gear.
The oil level in the reservoir depends on the steering wheel positions. therefore, measure the oil
level when the steering wheel is positioned at straight ahead direction (neutral).
