weird squeaky noise when idling ....
Hello guys, I'm Old new here with an 2004 Boxster base 2.7L with 177k miles all original glad to say.
for the past week I've replaced nearly all the pulleys (do to age and needed replacement) but on the left top the alternator pulley is fine (tested with belt off) seems fine but on the top right side the pulley has three 13mm bolts and when removal of the pulley the triangle part that's there make noise while hand spinning. What is that part ? I thank your for any help !
