Any auto parts store will have it just ask for belt number 845K6 for the 84.5 inch belt. The first 3 numbers represent the length of the belt and the K6 represents how many ribs the belt has. This is how serpentine belts are numbered.
i want to bypass my smog pump also by the belt. i have an a/c pulley still from the upr delete. so with ac still, and just removing the smog is it the 84.5 inch belt?
The easiest way to do it is to drive the car to AutoZone or wherever and fit the belt in the parking lot. I made 3 trips when I deleted my smog pump because I forgot to account for underdrive pullies. Just some advice that may save you some time in the future.
What I did was remove the Smog pump completely from the engine. Bolts to the back of the block and then down to your exhaust. Then you can pickup an extra pully. Just take a Measuring tape and run it around your pullies to give you a belt size. I got my at Autozone. They carry all types of belts. Good Luck!
