Step 20
Now it's time to bleed the system. Follow these instructions to properly bleed the system:
Now it's time to bleed the system. Follow these instructions to properly bleed the system:
- The vehicle’s battery should always be disconnected before any modifications are made.
- Make sure all of the fittings in the power steering system are tight.
- Raise all steering tires off of the ground.
- Fill reservoir with power steering fluid (never use automatic transmission fluid). PSC recommends either Swepco 715 or a GM power steering fluid that they supply the part number for. Leave the cap off of the reservoir.
(Fill level should be 1” below the top of the reservoir. On single ended cylinder applications this should be measured with the cylinder collapsed.) - Cycle the steering from lock to lock three or four times.
- Check fluid level in reservoir. Refill as needed.
- Repeat steps 5 and 6 until a consistent level in the reservoir is reached.
- Reconnect the battery. Replace the cap on the reservoir.
- Start the vehicle and let it run without any steering input for 30 seconds but be aware that if there is air in the system, there is a good chance you will smoke the pump. Do not start the engine until no air moves into the reservoir when the steering is turned lock to lock. You can under do it, you can't over do it.
- Turn off engine.
- Check and refill reservoir as needed, replacing cap when done.
- Start engine and cycle steering from lock to lock 10-15 times.
- Turn off the engine and let it stand for 10 minutes to allow air bubbles to work out of the system.
- Repeat steps 11-14 until there are no air bubbles visible in the reservoir.
- With the engine running, observe the fluid level in the reservoir. While looking in the reservoir,
turn off the engine. The fluid level should not change. - If the level does not change, check the system for leaks. If there are no leaks, test drive the
vehicle. If the level does change start over at step 4.
