hey everyone swapping out most of my pulleys since they all have play, every pulley other than my power steering, crank, and alternator (which is basically new since old one shredded a belt due to terrible axial movement) so I received all the tensioners and idlers last night and installed them waiting on water pump and a/c pulley to come in today but I noticed the new idler with grooves in the supercharger belt side has visible play when installed all the other pulleys were tight when I installed them. after i went to the store and tried a different idler and that had visible play too? ended up just putting the one I got in the mail online back on for now since it was cheaper. is this normal brand is acdelco and the other one from the store is gates. did I get 2 bad parts? also my water pump is only like a year old and as I said has noticeable play, can actually see the belt moving side to side on the tensioner while engine is running could it just be from everything else having play. water pump is the zzp brand have a acdelco replacement coming in the mail
