Replacing the serpentine belt on a 2017 Dodge Journey demands precision using the manufacturer's belt routing diagram to prevent engine damage or misinstallation. Always work on a cool engine in a well-ventilated area with safety gloves and eye protection.
Tools and Preparation
Gather these essentials:
- Belt routing diagram (found under the hood or in the owner's manual)
- Serpentine belt tensioner tool or wrench
- New compatible belt (e.g., Gates 6PK2260)
- Work light and socket set
Locating and Interpreting the Diagram
The diagram is typically a sticker near the pulleys. Identify key components:
- Crank pulley: Main drive point
- Tensioner pulley: Releases belt tension
- Other pulleys: Alternator, power steering, etc.
Verify the diagram matches your engine layout to avoid routing errors that cause slippage or premature wear.
Step-by-Step Replacement Guide
Follow these steps precisely:
- Use the tensioner tool to rotate the tensioner pulley clockwise, releasing belt tension.
- Remove the old belt while noting its exact path using the diagram as reference.
- Inspect pulleys for damage or debris, cleaning if necessary.
- Route the new belt according to the diagram, ensuring proper alignment on all pulleys.
- Release the tensioner slowly to secure the belt, checking for correct tension (no slack).
- Start the engine briefly to confirm smooth operation without squealing.
Critical Mistakes to Avoid
Prevent common failures by heeding these warnings:
- Incorrect routing: Causes belt failure; double-check against the diagram before final installation.
- Over-tightening: Damages bearings; allow the tensioner to auto-adjust without force.
- Skipping pulley inspection: Leads to quick belt wear; replace worn pulleys immediately.
- Ignoring old belt patterns: Match grooves to the new belt to avoid misalignment.
By adhering to the belt diagram and methodical steps, you achieve a reliable DIY replacement.
