    Comments about CARQUEST by Dayco Poly Rib Belt:

    I agree with what the other reviewer had to say about this belt. Normally I would be an advocate of the Dayco brand but not in this particular case. I have a finicky 1991 tercel and this belt would continually slip on the alternator and water pump pulleys. It didnt last much more than a couple of months and frayed fairly quickly. I opted to go with a Goodyear Gatorback belt for half the price and it worked much better. The extra grip is necessary to rid yourself of slippage and any unwanted noises, expecailly on the Tercels.

    Use Gates belts instead of these low quality Dayco belts and you will not have any problems. Same Gates belt is only .50 cents more.
