Flushing power steering fluid

14 The reservoir for the Electrically Powered Hydraulic Steering (EPHS) is located on the front left-hand corner of the engine compartment. Note: On some models with a high capacity battery, the battery and tray must be removed in order to access the reservoir filler cap. The fluid level is checked with the dipstick attached to the reservoir filler cap. Unscrew the cap from the hydraulic fluid reservoir, and wipe clean the integral dipstick with a clean cloth (see illustration) .

steering rack or gear . 2X2 - 4X4 engine . Depends on steering system .
When you turn the steering wheel, the steering gear rotates the pitman arm which forces the relay rod to one side. The tie rods connect to the relay rod with the ball studs. The tie rods transfer the steering force to the wheels. Use the tie rods in toe adjustments. The tie rods are adjustable. The pitman arm support the relay rod. The idler arm pivots on a support attached to the frame rail and the ball stud attaches to the relay rod.
The 2 tie rod are threaded into the tube and secured with jam nuts. Right and left hand threads are used in order to permit the adjustment of toe.

Power Steering System Description and Operation (w/o Electro-Hydraulic Steering)
The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive, cam-driven.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine
The 2 basic types of power steering gears are listed below:
• A recirculating ball system
• A rack and pinion system
In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft. A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod move the other tie rod.
In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the direction of the vehicle's front wheels.
The power steering pressure hose connects the power steering pump union fitting to the power steering gear and allows pressurized power steering fluid to flow from the pump to the gear.
The power steering return hose returns fluid from the power steering gear back to the power steering fluid reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid cooler.
In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the right and left chambers in order to assist in right and left turns.
Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to 1 side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or left.

Since you say gear oil I assume that it is a manual transmission. Here are codes and fluid type/capacity
Transmission fluid Capacity 2.0 liters
Transmission code: DYP, ECW, EFG, ERS, FBV, FBX, FBY, EGY, EVR, EZK, FCF Type G51 SAE 75w-90 (synthetic oil)
Transmission codes: DQY, DBZ, DZQ, DZC, EGC, EGF, EKG, EMR, EMS, ENH, ENJ, EBJ, EBP, EBQ, EZH, EWW, FBW, EGR, EBN, EGT, EGX, EGU, EHC, FDS, EHA Type G50 SAE 75w-90 (synthetic oil)

Thank you for using Fiya.

No, it's usual for power steering fluid to be the same as transmission fluid. they both are hydraulic type fluid with similar system requirements.

good luck

Power steering fluid level checking:
- vehicle stationary
- front wheels in straight ahead position
- engine at normal operating temperature
- remove cap with dipstick from expansion tank and wipe off
- reinstall cap with dipstick and remove again
- fluid level between "min" and "max" markings
- top off with G 002 000 hydraulic oil if necessary
Power steering system capacity is around 1 liter, but it is not necessary to periodic change the hydraulic oil!
If oil level has dropped to the "min" marking, check power steering system, including hoses and lines.
It is not enough simply to top off the hydraulic oil !!!
