Thread: Ps pump squeal after flush

I have an 07 buick allure..... my other car was a grand prix hence why im here but i the knowledge here is awesome..... and an allure is just a ifferent shell lol... 3800 series 3.
Anyways i followed the instructions on this site, but i didnt start the car when i did it. I removed the return line and turned it 90 degrees -the flexible line off the pump that goes into a compression fitting. Maybe i wasnt supposed to move it but it did move freely. I put the return line back on, filled the resevoir and the pump was squealing like i had no oil.... but there was and it was all foamy. I tried bleeding it while it was running on the ground with no luck..... but nothings leaking.... i dunno %$#@.
Thanks guys

I've always bled the PS system with the front end OFF the ground with the car running. Last time I did a pump replacement it took almost 30 min. do this until all the air was bled out and the foam stopped. I just used 15 turn cycles, shut it down and checked the level each time. There was less foam and pressure when removing the PS cap each time until it was just fluid. It can take more time depending on how much air is trapped in the system.

Thanks for the reply..... is it possible for a leak in the return line to suck in air but not leak fluid?? Its squealing pretty loud but il try jacking ot up and turning side to side w/out hitting the stops. I wonder if it damages the pump squealing like a pig
