Fitted brand new power steering pump the other day as my mine died
After fitting, of course there was air in the system. So did the usual bleeding procedure of taking the lid off the fluid reservoir, jacking up the car and turning wheel from side to side. The whining noise got alot quieter but it is still there. Tried this procedure for half an hour. Left the car over night with lid off (allowing air to travel to top and hopefully escape) and tried bleeding again but still no luck. The power steering works fine and there are no bubbles in the fluid when in normal operation.
Pretty sure it is still air trapped in the system as when i turn wheel from left to right a few times and check the reservoir, bubbles appear in the fluid for a minute or so.
So........anybody any tips or tricks on how to extract trapped air from the power steering system as the conventional way doesn't seem to be doing the job
Thanks in advance
