POWER STEERING FLUID
Draining and RefillingINFOID:0000000009461266
DRAINING
1. Disconnect the high and low pressure piping from power steering gear.
2. Drain power steering fluid into a suitable container.
REFILLING
1. Fill power steering reservoir while checking power steering fluid level.
2. Bleed air from power steering hydraulic system. Refer to ST-30, "Air Bleeding Hydraulic System"
.
3. Check for power steering fluid leaks.
Air Bleeding Hydraulic SystemINFOID:0000000009461267
AIR BLEEDING HYDRAULIC SYSTEM
If air bleeding is not complete, excessive noise in the power steering oil pump will be present.
1. Make sure engine is off.
2. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles are no longer being generated in the reservoir.
3. When the power steering fluid level lowers, refill the reservoir. CAUTION:
Do not allow the power steerin g fluid level to drop below
the hatching area.
4. Repeat steps one and two until the power steering fluid level stabilizes.
5. Start the engine and run at idle.
6. Turn the steering wheel from the full right stop pos ition and then to full left stop position several times.
Repeat until bubbles or fluid discoloration are no longer being generated in the reservoir.
7. When the power steering fluid level lowers, refill the reservoir.
8. Stop the engine.
9. Verify proper power steering fluid level. Power steering fluid level should be between the hatching area of the indicator on
the power steering reservoir tank cap.
