Power Steering Gear and Pump Leaks for Cadillac Seville 2000
The purpose of these procedures is to pinpoint the location
of the leak. In some cases, the leak can be located easily. Seepage-type leaks
may be more difficult to locate. Use the following method to locate seepage
leaks:
- With the engine OFF, wipe the power steering system dry.
- Check the power steering fluid level. Add power steering fluid
if necesary.
- Start the engine.
- Have someone else turn the steering wheel from stop to stop several
times. Do not hold the steering wheel in a stop position for any length of
time or damage to the power steering pump could result.
- Locate the power steering fluid seepage leak.
- Repair the power steering fluid leak.
