S50 swap e36 Power steering issues

[e30s50dan]

well i flushed the system today and put in ATF DEX 3 ,and is still whinning like a bitch...looks like i will order a reman pump

[e30s50dan]

Sorry to bring back this tread. But after putting up with the whinning noise, I decided to get a rebuilt one from advance auto. Installed it yesterday and for a while there was no noise,so I thought I got this,but today the noise is back and as loud as the other two pumps. It only whines after it's warm and I turn the steering Again sounds like a bad pump!! WTF. SOTS. Any ideas. Btw fresh ATF fluid and still have the same leak

Lol, mine whines a little too. I've noticed it getting quieter though, I think mine may be because the pump wasn't used for a while. There's only so much going on with a P/S system. Could it be the rack?

[e30s50dan]

It's the same rack and pump that was in my m50 318. I just unbolted complete front subframe and rack and moved to my 325 w/S50

Stupid question, but how's your belt?

[e30s50dan]

^^ not stupid..its been changed out..why do you ask?

[Schwarz325]

I was thinking maybe it just faded from heat and it was slipping.

[e30s50dan]

Funny you should mention the belt. If you go to autozone or advance they have two different length belts. 51.3 and 51.5. I have the 51.5. Pelican parts shows only the 51.3. I just bought a new tonight. See how it goes. I know it's only 1/4 in shorter but I've seen stranger things

dan, have you had any luck with this? im getting something similar with an m50 swap (with e36 rack)

Well yea. I have put on the smaller belt and cross my fingers, it's been great. I didn't want to jinks it but the new smaller belt must have done it Make sure you get the 51.3 belt. Advance auto shows both. Good luck
