Review on Dayco 5070763 Serpentine Belt by Joseph Long

I was able to replace it myself along with the alternator. To access the hydraulic tensioner, you will need a 19mm socket for a ratchet wrench or houndstooth wrench less than 3 inches apart. First I had to put the head on the tensioner head and then turn the wrench to make it fit. You will also need a good shop light and a long screwdriver or hard stick/rod to get the belt onto some of the lower pulleys.
