Serpentine belt replacement cost
for a Nissan Altima

Replacing the serpentine (accessory drive) belt on a Nissan Altima involves removing the old belt and installing a new one around the engine's pulleys, typically requiring some access panel removal. Cost is primarily driven by the model year and engine size, which determine belt routing complexity and part price. Labour time is generally low, but some V6 models or newer years with tight engine bays can increase the time required.

Tips before you pay

Check the belt tensioner pulley for smooth operation and replace it if noisy or wobbly while the belt is off.
Take a photo or draw a diagram of the belt routing before removal, especially on V6 models.
Use a proper serpentine belt tool or a long breaker bar to relieve tension on the automatic tensioner for safe removal.
