I am new to working on cars, I can use any help that I can possibly get. I am lost here...my serpentine belt broke a few days ago and I just figured out that it was the tensioner pulley. I had to go and buy the whole part instead of just the pulley, and now the new tensioner is a bit different. This new one has a PIN lock in it and I have NO idea what to do with it. I have questions like..what sort of tool do I use to move it if I need to move it at all? Also, I installed the tensioner part and I couldn't find how to lift it up in order to move it to make way for my new serpentine belt. What am I missing here...please help. Any help would be great, I need to make it back home to another state and I cannot afford to pay for a mechanic so I am extremely grateful for any info I get.
