pancing

Does anyone know if the ps pump is supposed to vibrate? I changed fluids and broke the o rinf under the cap but fitted it so the cap wasnt loose. I dont remember if it vibrated before, does anyone know or have an answer? If anyone could touch their cap when the car is warm and get back to me? Tia.

Mine runs with the engine; if there is an off axis vibration, could be a bearing in either pump, or the drive pulley.

So it does vibrate, mine isnt shaking anything loose, i just wanted to confirm that it actually vibrates, i don't remember if it did or not.

I would the no short of a full on screaming bearing or things coming loose in the engine compartment, should be good...

The only vibration you should feel should match the frequency of the engine.

Yeah its been humming a bit before and after the flush, hopefully i didnt introduce air into the system.

If you totally changed the fluid you probably got air into the system which will make the pump whine until the air works itself out. Several lock to lock turns while running and making sure the reservoir is full will probably do it. It may not be full
