Some cars have a spring-loaded tensioner pulley for the drive belt to maintain the proper tension on the belt as it wears and stretches over time. This helps to prevent slippage and ensure efficient power transfer from the engine to the various components. Other cars may not have a spring-loaded tensioner pulley because they use a manual adjustment system that requires periodic adjustment by the owner or a mechanic to maintain the correct tension on the belt. The choice of design may vary based on the manufacturer's preference for ease of maintenance and durability. **
