Power Steering System Leak Test

Power Steering System Leak Test

General Procedure
Inspect the following:
^ The fluid reservoir for overfill.
^ Fluid for aeration and overflow.
^ The hoses for loose connections.
^ The torsion bar, stub shaft and adjuster seals for leaks.
^ The component sealing surfaces for damage.

CAUTION: Verify the exact point of the leak. The point from which the fluid is dripping is not necessarily the point at which the system is leaking. When service is required, clean the leak area upon disassembly, replace the leaking seal, check the component sealing surfaces for damage and reset the torque bolt to specifications, where required.


External Leak Check
The purpose of this procedure is to pinpoint the location of the leak. In some cases, the leak can be easily located, but seepage-type leaks may be harder to find. To locate seepage leaks, use the following method:
1. With the engine off, wipe dry the complete power steering system.
2. Check the power steering fluid level in the pump's reservoir. Adjust the fluid level as necessary.
3. Start the engine. Turn the steering wheel counterclockwise and clockwise from stop to stop several times.

CAUTION: Do not hold the steering wheel at a stop for any length of time as this can damage the power steering pump.

4. Find the exact area of the leak and repair it.
