In this video, I show you how to remove the drive belt (serpentine belt) on a 2012-2016 Chevrolet Malibu 2.5L. Knowing how to safely release the tension on the belt and route it off the pulleys is an essential skill for a smooth DIY vehicle repair, saving you money and keeping you organized before you start swapping out components.
Common signs that your Drive Belt needs to be replaced include:
- A loud squealing, chirping, or squeaking noise coming from the front of the engine, especially on cold starts or during tight turns.
- Visible signs of wear on the belt, such as cracking, fraying, chunking, or severe glazing on the smooth side.
- Battery/Charging system warnings on your dash, heavy steering, or engine overheating if a worn belt slips or snaps completely.
Step-by-Step Overview:
- Access: Gain clear access to the front passenger side of the engine bay (removing the front right wheel and inner splash shield gives you the best room to work).
- Release Tension: Locate the drive belt tensioner pulley. Use a breaker bar or serpentine belt tool with the correct socket to rotate the tensioner arm, compressing the internal spring and releasing tension on the belt.
- Remove: Carefully slip the slackened belt off the nearest accessible pulley (like the alternator or water pump), slowly release the tensioner arm, and then fully remove the old belt from the remaining pulleys.
Safety First: Serpentine belt tensioners are under heavy spring pressure and can snap back with extreme force if your tool slips. Always ensure your socket or wrench is completely seated on the tensioner, protect your hands and eyes by wearing durable gloves and safety glasses, and stay completely focused and attentive throughout the entire process.
