Been noticing my belt chirping away after I replaced my stock alt with a rebuild. While they were rebuilding I had them swap the 2.8 alt pully with a 3.0. As that was the only size I could get my hands on quickly. Now the belt only chirps on startup and goes away when it's warmed up. I have a brand new belt fitted while I still I had the 2.8 pully on. My question now is am I really going to have to swap to another new belt just for a 0.2inch pully swap?
