quick install, no more squeak

Easy install, don't forget it's reversed thread on the bolt. I replaced the belt also, got rid of an anoying squeak.

Had to modify the dust cover (the big flat washer between the head of the bolt and the bearing)to maintain an OEM function. The bearing spins smoothly, but the whole assembly seems to have excessive side-to-side play. We'll see how long it last.

            I spent over an hour looking on line for a replacement idler for my 1994 Ford Ranger 2.3, because the pictures on the site did not remotely resemble the one that failed. The original has guide walls on either side of the pulley, but I was unable to find the identical item at Advance.com or any competitor. Have no hesitation ordering this item as a replacement, even though it appears quite different. The outside and inside diameters are identical to the original equipment and the item works perfectly.

              Comments about Dayco No Slack Idler Pulley:

              Just completed replacing this smooth pulley & the ribbed tension pulley. Use an 8mm socket to remove the air tube that runs from the air filter housing to the throttle body. A 15mm socket will remove the pulley. The new pulley does not have the shoulders on it that helps prevent the belt from riding off the pulley, but that is not an installation or performance issue. Discard the little bolt keeper on the back of the original pulley. Use the original bolt & washer to install the new pulley. Make sure the belt is seated on all the ribbed pulleys. If replacing the ribbed tension idler pulley, use a 13mm socket and access from beneath the truck. Easy install.

                I have a 1997 GMC K1500 SLE Z71 off road 4+4 5.7L and was wondering if it matters to use a smooth idler or a grooved idler and what is the best quality product for the money. Thanks Tim

                  I'm happy to help, Tim! For your 1997 GMC K1500 SLE Z71 4x4 5.7L it will depend on what your vehicle has for an idler pulley currently. If it is grooved it must be replaced with grooved. Smooth must be replaced with smooth. From what I see the grooved pulley tends to be for the trucks without A/C. Based on your serpentine belts routing, either the smooth side of the belt or the grooved side of the belt will come into contact with the idler pulley and that will need to match.

                • A:

                  Don't know where the "answer man" came up with no for an answer but YES, most definately. You have to replace the belt "spring tensioner" with same as you have on vehicle but you can interchange the tensioner "pulley" that's on it,, to a bigger size tho. GM has problems with the tensioner spring losing torque after only a few thousand miles, especially on the super charged engines, then the belt starts chirping and wear grooves on out side of belt, (flat side), from slipping. To remedy that, replace the pulley on spring tensioner with pulley that is 1/2 inch bigger. That only gives you 1/4 inch more from center most point but that puts enough/more torque on belt to prevent the belt from chirping and wearing out more pre-maturely from slippage.
