Porsche 944 workshop manual vol 4




















Run this check for max. If the check requires more time, allow for a short break every 10 seconds. Checking the power steering fluid level Screw off supply tank cover. The supply tank is fitted to the right-hand wheel house wall inside the engine compart- ment. Run engine at idle. Wipe off dipstick, screw cover back on and remove again. The fluid level must be between both marks.

To bleed the complete system after new steering components or lines have been fitted or after excessive hydraulic fluid los- ses have been remedied, start engine several times and turn off immediately as soon as it has started. This process causes the fluid level in the supply tank to drop rapidly. The supply tank must never run empty. As soon as the fluid level no longer drops when the engine is started for a short mo- ment, start the engine again and let it run at idle speed.

Turn steering wheel rapidly from lock to lock several times to allow air to escape from the cylinders. When reaching the end position of the piston, do not pull harder on the steer- ing than is required for turning the steering to avoid unnecessary pressure buildup. Check fluid level while performing this opera- tion. If it continues to drop, top up until the fluid remains at a constant level and no more air bubbles rise in the supply tank when the steering wheel is turned.

With the engine running at idle, establish correct fluid level between min. Adapter High pressure hose up to bar, 1. Made locally for pressure gage item no. G e n e r a l I n f o r m a t i o n Tester pressure gage is installed between power pump and pressure line. If using old pressure gage, install in correct position.
