Do PS pumps require a break-in period? Is it normal for them to make a bit of noise (sounds like bearing noise) when they are first installed, and the wheel is turned at idle? It's a mopar pump, if that makes a difference.

I only ask because I know smog pumps DO tend to make a bit (or even a lot) of noise for the first 500 miles or so. But it seems to me that the PS fluid would mask or eliminate any such noise.

Thanks for the reply. P/S cooler, huh? I'd hate to do that to this car ('68 GTX), but if that's what's required then...

I suppose after 30+ yrs of these units being rebuilt, some of the internal tolerances just won't be what they used to. Just so long as they supply pressure and don't leak, that may be all you can ask for.
