tightened all my belts on the 305 h.o. bec they were squeaking, the only belt that kept squeaking was the power steering belt that ran from the a/c to the power steering and water pump. but it isthe power steering that's creaking. I dnot really have alot of time to work on my car since I work 5 days a week and go to school full time so I used that belt dressing to see It cal eliminate the squeak until I have time to replace the belt(it's a little glazed). and at idle it sounded fine but when I hit the gas it started to creak alot, will changing the belts eliminate the creak? could it be the pulley? the pump? thanks for any responses.
