    Comments about Dayco No Slack Belt Tensioner:

    Belts were squealing during rain and humid days. My 2005 GMC Sierra crew cab has 130k miles. Decided to change belts and tensioners. Piece of cake install. Took less than 15 minutes. No squeal.

        The part was used to replace the old worn out factory part that was 13 years old. I liked the "No slack" design and the ease of installation. So far the customer [my picky Dad] is very pleased. I will use this brand over and over again.

        Bought one to replace an original off my truck that had 105,000 miles. The first one broke in 2 days. They warranty covered it. The second one seemed to get play between the pulley and spring housing and would let the belt come off. Warranty covered it and I got another. This third one did the same as the second and I just got a refund and went and bought a Gates tensioner. It is made differently and is holding up just fine.

                    Always check the tensioner parts before you make the belt change. If you don't you will be taking off parts multiple times.

                        A:

                        I'm glad to assist, Bill! The tension does not need to be adjusted on this Dayco No Slack Belt Tensioner (Part No. 89253) The tension is already set, to release the tension you will need to use the correct size drive socket on a breakover bar, ratchet or serpentine belt installation tool to rotate the tensioner arm to release the tension. Once you remove the tool with the belt in place, the tensioner will then hold the belt in place.

                        The installation instructions are located here: http://www.daycoproducts.com/dpdata/images/IS253.PDF
