Power Steering Belt

You should replace the negative battery cable.

Since I just replaced mine, I will comment. The brackets consists of 3 pieces. 1 on the engine, 1 for the pump and a plate the slides over the 2 bolts that attach the pump bracket to the engine bracket. Your picture shows that plate is missing. Without that plate you will never be able to tighten the bolts correctly.

Now for the bolts. The top bolt slides into the slot on the top of the engine bracket. The bottom bolts slides thru slot on the engine bracket and is used to adjust the tension for the belt. There is a square hole next to the top bolt that you can use a socket extension to adjust the brackets.

I used a stock off the self replacement belt. It was slightly tighter then necessary and I needed to "turn" the pulley to slide the belt on. Once on, it was very easy to use a socket handle with extension to adjust the tension on the belt. Once set, just tighten the bracket bolts, starting with the bottom bolt.
