Rubbing noise on starting 06 Hawkeye. Both accessory belts no longer central on pulleys.
Belts replaced a year ago. Don’t seem loose on initial inspection.
Do I need to be suspicious of bottom pulley with rubber insert or is it safe to reposition and retighten ?

 

Slacken the two other belts a wobble the bottom pulley better safe than sorry.

 

main crank pulley is rubber bonded / damped and they can fail..........most likely issue

 

Thanks for the replys guys

pulled the belts and it looks like I need a pulley

very lucky it didn’t come adrift while on bypass

has anyone posted this before ?

 

If left it usually eats the timing covers and causes awful bother.

 

Does anyone know if the pulleys vary across Impreza versions or are they interchangeable?

 

They vary by engine size and "grade"

For Hawkeye STI and WRX it's p/n 12305AA251 superceded by 12305AA252
