Question about power steering.

[2003 mustang gt modded]

Hello, when I was buying my mustang the owner put a one of those battery assist jumpers, ( I don't know what they are called), anyways it forced the power steering high press hose to get cut on the pulley.

I drove like that for about 100 miles without any fluid. Then installed new hose and drove for about 6k miles. Everything worked, but pump was noisy and had leak somewhere.

I just installed new pump, but haven't ran car yet... and most of liquid is new because I was adding so much fluid due to leak, about 3 qt to 4 qt Or more. ( But oil leak does get rid of metal fragments)

I worry that there may be metal fragments in system that will damage new pump.

Tell me what you think? Do I need to continue to flush. If yes what is an easy procedure?

Would be high chance of metal particles in the system due to pump running dry for 100 miles.?

Should I just throw a inline filter on it.

Can I use compressed air to force all remaining fluid out of system?

Thank you.

There should not be any metal in it. The umm... "paddles" or vanes in the pump are made of a phenolic material.

You could even rebuild the old one if you were so inclined.

It’s not the hundred miles it’s also the idle time as the pump was still spinning and the rpm’s. You also ran the rack dry for those 100 miles and they are not designed to run dry either.

Once you get metal in the power steering system it’s down hill from there. If it were me I would pull the track and replace both lines. This will ensure you don’t have residual metal in the system which will just take it all back out.

Purging the system is pretty easy.

Biggest issue with most of the pump replacements is asking why the pump failed. Most of the time the fluid has bass boat glitter in it which is the rack failing. Rarely have I seen a pump fail and then everything is fixed by installing a new one. Usually the new one fails shortly after that and there is glitter in the fluid.

I have seen where a pump is replaced and the new pump is just fine because the owner of the car pays attention and notices the fee of the steering is different or catches a difference in sound. In this case the issue was caught fast enough the rack wasn’t damaged...

Thank you for suggestions and sharing some info. I decided to your use compressed air to get anything remaining in the system out. And i have used inline magnetic filter trap any metal fragments .

You will need to replace the pump (sure might whine like hell after 100 miles and no fluid)
The C2 pumps Do have a spring loaded metal vane and rotor with metal slippers
Do the self bleed procedure with new ford fluid, and then replace it if the whine drives you crazy
