Replacing the serpentine belt on a 2012 Dodge Avenger is a simple DIY task with the aid of a routing diagram. This guide ensures precision.
Preparation
Gather tools: socket wrench or breaker bar for the tensioner pulley, new serpentine belt (matching specifications). Verify the engine is cool and off. Reference the diagram for belt routing path.
Belt Removal
- Identify the automatic tensioner pulley.
- Use the wrench to turn the tensioner clockwise, releasing belt tension.
- Slide the old belt off pulleys, noting its path via the diagram.
Belt Installation
- Align the new belt using the diagram as a guide; route it around crankshaft, alternator, power steering pump, and idler pulleys.
- Apply tension to the tensioner pulley and slip the belt onto place.
- Release the tensioner gradually to seat the belt securely.
Final Checks
Start the engine briefly; listen for abnormal noises. Confirm belt alignment with the diagram for optimal function. Misrouting may damage components; always double-check the path.
