So you're saying the cold makes the rubber brittle? But why does it curl up exactly like a banana? I've seen belts crack or snap, but the curling is new. Does it happen fast or over time? Is there a way to prevent it, like storing the car inside? Just wondering if this means the belt is totally shot or if it can be saved.
Hmm, not sure about the cold being the main cause. Seen plenty of belts in freezing weather that just crack straight across. That tight curl makes me wonder if the belt was misaligned for a long time, wearing one edge way down. Once that thin edge gives out, it can peel back. A really worn pulley might do that too, grabbing it weird.
