Signs of fan belt on expedition is going out?

Signs that the fan belt on your expedition may be failing include squeaking or squealing noises when the engine is running, visible cracks or fraying on the belt, and overheating of the engine. You might also notice poor air conditioning performance, as the fan belt powers the cooling system. If the belt becomes too worn or breaks, it can lead to engine damage, so it's important to address these issues promptly.
