Comments about CARQUEST by Dayco Poly Rib Belt:

The belt was a little longer than the original, by 5mm, but with the tensioner it was not problem and seems to fit fine. It was easy to install with exception that the tensioner pulley where the belt had to be turned upright for removal and install. Watch UTube for information and be sure to looked at the routing when pulling the belt and replacing it. The 2000 Cadillac Deville had the original belt still on it and at 90,000 miles it still looked good, with no noticeable wear. As a precaution I replace the belt. It has been fine after a few hundred miles. Time will tell whether it is as good as the original belt.

Comments about CARQUEST by Dayco Poly Rib Belt:

On a Cadillac Northstar engine, this is *NOT* the main serpentine belt for the A/C, alternator and power steering - this is the smaller belt that drives the water pump only.
