STEERING GEAR - POWER RACK & PINION 

         1993 STEERING
         Volkswagen - Power Rack & Pinion

         Corrado SLC

         DESCRIPTION & OPERATION

         System consists of a vane pump, rack and pinion steering
gear, and an oil reservoir. Vane pump draws fluid from reservoir and
supplies it to flow control valve. Control valve directs fluid to
appropriate side of rack piston.

         LUBRICATION

         CAPACITY

         Fluid capacity is approximately 1 qt. (.95L).

         FLUID TYPE

         Recommended fluid type is VW Hydraulic Oil No. G 002 000.

         FLUID LEVEL CHECK

         Remove reservoir cover. Start engine and let idle. Fluid
level should be between MIN and MAX marks on reservoir.

         HYDRAULIC SYSTEM BLEEDING

         1) Start engine and let idle. Ensure fluid is at proper
level. Turn steering wheel from lock to lock several times quickly.
         2) Continue until fluid level remains at reservoir mark.
Ensure no bubbles appear in reservoir when steering wheel is turned.
Shut off engine. Ensure oil level does not rise more than 3/8" (10
mm).

         ADJUSTMENTS

         POWER STEERING PUMP BELT

         Loosen nuts on pump mounting bracket. Turn adjuster bolt
until belt deflection is 3/8" (10 mm) at center of belt. Tighten nuts
to specification.

         TESTING

         HYDRAULIC SYSTEM INSPECTION

         Ensure fluid level is okay. Check service belt condition and
adjustment. Ensure hoses are not kinked or leaking.

         PUMP PRESSURE TEST

         Install Pressure Gauge (US 1074 B) between pressure hose and
pressure line of valve housing. Start engine and let idle. Close
valve. Leave valve closed for no longer than 5 seconds. Pressure
should be within specification. See POWER STEERING SYSTEM PRESSURE
table. If pump pressure is not within specification, replace pump.
