if its the Power steering belt that needs adjusting, this if done by changing the shims around from memory??
when you start it from cold,let the belts squeal. DON'T rev it.. quick squirt of WD40 on the alternator belt. if the squeal stops. thats the belt that needs adjusting. if it doesn't then squirt the Power steering belt.. if it stops now.. theres the problem
both are easy enough to adjust.
