Review on Dayco 89007 Tensioner Idler Pulley by Leo Govindan

Made in the USA! I think it's equal to ACDelco and half the price of buying it. For the Buick PA, this is a 3 inch idler pulley. I was able to use the original dust cover without the fasteners (this pulley does not include a new dust cover). Dayco states on the packaging that the dust cover is not needed as the bearings are covered. Dayco recommends not using the dust cover if it binds the pulley.
