Bleeding power steering fluid
#1
![Default](/forum/images/icons/icon1.gif)
Any tips / proper procedures on new power steering fluid and bleeding out the air?
I just replaced my power steering rack on my '78 w/ a post face-left steering rack; engine is a converted small block Chevy w/ the Chevy power steering pump if relevant.
1. Is there a bleed valve on the rack or anywhere within the system?
2. Fluid recommendations?
3. Any specific tips?
Thanks, Steve

My tried and true method:
- Add fluid to reservoir to cover the innards of the pump.
-Start engine and run for just a few moments; the fluid level in the reservoir will drop a bit
-Add fluid to reservoir
-Slowly turn steering wheel from lock-to-lock a few times
-Recheck fluid level
-Turn lock-to-lock a few more times
That's it.
If you feel a 'hitch' in the steering you may still have air in the system
Jaguar calls for Dexron ATF. I use Dexron or Type F or Type FA ATF; never had a problem with any of them. I don't think the P/S system is really that sensitive to fluid type. Some use Power Steering Fluid with good results.
I've never known....but often intended to research the difference in properties between ATF and P/S fluid
For ages and ages Jaguar used GM/Saginaw pumps.....and GM calls for Power Steering Fluid in their pumps rather than ATF. So.....?

Just to add a note to Doug's post: if you just top up the reservoir and (front wheels off the ground) turn the steering lock to lock several times, the fluid will get drawn through the system without the engine running. Re-top up afterwards. Then once you do start the engine, check the fluid level after a couple of minutes wheel action.
