Misfiring engine â A worn cambelt may cause your engine to misfire due to engine components running out of time with each other.
Car not starting â If the cambelt has wholly snapped, the car will not be able to start. The crankshaft and camshaft will not be able to operate without a functioning cambelt.
Rough idling â The cambelt wraps around gears with metal teeth attached to them. These teeth make contact with the engine crankshaft and camshaft, keeping them in time. If the cambelt jumps a tooth, your engine will have the wrong engine timing and your engine will run roughly, especially while idling and accelerating.
