Unstable C-4772 Faulty Engine

I have a car with a faulty engine (I love this new feature). I could not find a way to repair it. I tried removing it. when I looked at it as an item it said it had a bad drive belt. I have a replacement, but I have no idea how to apply it. My guy has no way of lifting a 660 lbs engine so I can’t attempt to fix it with a welder, how does one fix the issue?

second the OP
