Hi there. Rattling noises can be caused by very many things. The noise needs to be isolated to determine whether the noise is internal (inside the engine or transmission) or external (an accessory component, e.g., A/C compressor, water pump, alternator, serpentine belt tensioner assembly, idler pulley, etc.). Repairing or replacing components without proper diagnoses could be expensive and time consuming. I recommend having your vehicle’s rattling noise inspected and repaired by a certified technician, such as one from YourMechanic.
