This will cause the pistons to strike the valves that left open.
What does a loose fan belt sound like?
A loose drive belt will often be noisy, squeaking a bit, or emitting a high-pitched squeal. The most obvious sign of a loose drive belt, though, is in its appearance and tension. Belts are used to rotate components on the engine assembly, such as a coolant pump (water pump).
