Check Vehicle Fit

Dayco was first to develop a v-belt with the raw edge sidewall construction; which maximizes pulling power and facilitates controlled slippage around pulleys. The raw edge construction is combined with Dayco’s patented cogged top design to ensure the top performance that today’s vehicles and drivers demand. Dayco Top Cog V-Belts meet or exceed SAE J636 and J637 specifications. This Top Cog V-Belt is another Dayco product proudly made in the USA.

Product Features:
  • The Top Cog design delivers more flexibility and increases airflow around the belt, so it runs cooler and lasts longer than most competitive belts
  • Three plies of rubber impregnated fabric on the bottom of this belt delivers excellent durability, strength and resistance to dirt and other road debris that cause belt wear
  • A specially formulated treatment of the polyester cord provides the strength, stability, and reliability that are required of a premium quality v-belt
  • Made with specially formulated rubber compounds, this belt is highly resistant to extreme under hood temperatures that can cause premature damage to under engineered rubber compounds

Comments about CARQUEST by Dayco V-Belt, Top Cog:

After about 11 yrs, I decided to replace all the belts, as I did when I bought the '88 Cadillac in '02, because dry rot cracks were visible and some of the top cog blocks were disappearing !! Because of this, I decided to change back to the smooth top belts thatI bought from another parts store, but alas, all I've had was trouble with the Power Steering belt wearing out oddly and breaking within 5 weeks of installing !The other smooth top belts have not given me trouble, but the P.S. belt is the next to last belt in order on the pulleys, so that means removing 3 other belts to replace the P.S. belt THEN re-installing the 1st 3 again !!Aaaargh ! I found that there ARE differences in widths, depths, lengths, etc between the all belts made, so check before you buy !

      This is the drive belt that goes from the water pump to the power steering pump, this is not the power steering pump pulley. For further assistance you can contact us at 1-877-ADVANCE (1-877-238-2623).
