Steering Gear: Service and Repair
Start-Up Procedure, After Power Steering Gear Service
ROSS INTEGRAL POWER STEERING GEAR
Upon initial engine start-up after a power steering pump or steering gear overhaul, there is frequently noise and aeration. This is due to air trapped in the
overhauled unit, which mixes with the surging fluid and causes aeration. The problem can be minimized using the following procedure.
1. Disconnect the ignition control module (ICM) to prevent engine from starting.
2. Fill the power steering oil reservoir.
3. Crank the engine with the starter motor and continue adding fluid until the level remains constant.
NOTE: Be careful to avoid prolonged cranking as the battery can be drained and the starter motor damaged.
4. Rotate the steering wheel approximately 30 degrees each side of center while continuing to crank the engine.
5. Recheck the fluid level, and fill as required.
6. Reconnect the ignition control module.
7. To clear fault codes, disconnect battery for one minute, and then reconnect battery.
NOTE: When the battery has been disconnected and reconnected, some abnormal drive symptoms may occur while the powertrain control module
(PCM) relearns its adaptive strategy. The vehicle may need to be driven 16 km (10 miles) or more to relearn the strategy.
8. Start the engine, and allow it to run for several minutes.
9. Rotate the steering wheel from stop to stop.
CAUTION: Do not hold steering wheel in the far left or right position; damage to power steering pump can result.
10. Shut off the engine. Recheck the fluid level, and add as required.
