When flushing the system pour some of the oil from the system through a napkin or coffee filter. If metal particles are found, the pump must be replaced. Proof that the procedure was followed must be noted on the repair order for the warranty to be valid. All port threads were in good condition after assembly and testing. Use proper torque specifications when tightening the power steering hose fittings. NOTE: No warranty credit will be issued for stripped threads.
Before bleeding: Inspect steering system.
Check, and correct as needed:
*Hoses must not touch any other part of the vehicle.
Steering system noise could be caused by hose touching frame, body or engine.
*All hose connections must be tight.
Loose connections might not leak but could allow air into system.
How to bleed:
- Switch ignition off.
- Turn steering wheel full left.
- Fill fluid reservoir to “FULL COLD” level. Leave cap off.
- Raise front wheels off ground.
- With assistant checking fluid level and condition, turn steering wheel lock-to-lock at least 20 times.
*On systems with long return lines or fluid coolers, turn steering wheel lock-to-lock at least 40 times.
*Trapped air may cause fluid to overflow. Thoroughly clean any spilled fluid to allow for leak check.
*Keep fluid level at “FULL COLD.”
- While turning wheel, check fluid constantly.
*No bubbles are allowed.
*For any sign of bubbles, recheck connections. Repeat step 5.
- Start engine. With engine idling, maintain fluid level. Reinstall cap.
- Return wheels to center. Lower front wheels to ground.
- Keep engine running for 2 minutes.
- Turn steering wheel in both directions.
- Smooth power assist.
- Noiseless operation.
- Proper fluid level.
- No system leaks.
- Proper fluid condition.
*No bubbles, no foam, no discoloration.
If all proper conditions apply, procedure is complete.
