Special Conditions
Fluid
- Fluid must be completly free of bubbles and foam. In step 5, be alert to periodic bubbles that could indicate a loose connection or leaky O-ring seal in either the return hose or pressure hose.
- Discolored fluid (milky, opaque or light tan color)
Switch ignition off. Wait two minutes. Recheck hose connections. Repeat step 7-10. If condition still exists, repeat and check for possible cause:
- Return hose clamps.
- Return hose O-ring
- Pressure hose O-rings
- Gear cylinder line O-rings
Fill system and repeat bleed procedure for each possible cause. Repeat steps 7-10 to verify if fluid leeak has been eliminated.
Noise
Pump whine or groan.
With engine running, recheck hoses for possible contact with frame body or engine. If no contact is found, follow one of the methods below to to cool down fluid and repressurize system.
- Method 1 - Normal cool down:

- Install reservoir cap.
- Method 2 - Partial Fluid Replacement:
- Switch engine OFF.
- Use a suction device to remove fluid from the reservoir.
- Refill with cool, clean fluid.
- Install reservoir cap.
After either metod of cooling, start engine and allow engine to come up to operating temperature. If noise persists, replace power steering pump. Refer to Power Steering Pump Replacement (2.0L Diesel LNP) , Power Steering Pump Replacement (1.6L LDE and 1.8L 2H0) .
