[Functions]: A-Premium engine serpentine belt drive kit usually locates at the front of the engine and wraps around a set of sprockets. It ensures the connection between the camshaft and crankshaft, making the pistons and valves work together in the correct sequence. It will help the engine run normally, improve fuel efficiency, and thus effectively optimise the engine's performance.
