Preparation and Safety
Ensure the engine is cool, disconnect the negative battery terminal, and gather necessary tools: serpentine belt tensioner tool (or wrench), new serpentine belt for 2017 Dodge Journey 2.4L, safety gloves, and flashlight. Always follow vehicle-specific procedures to avoid injury or damage.
Serpentine Belt Routing Diagram
The belt routing for the 2017 Dodge Journey 2.4L engine follows a standard path. Starting from the crankshaft pulley, the belt travels:
- Crankshaft pulley (drive)
- Generator pulley
- Power steering pump pulley
- Air conditioning compressor pulley
- Idler pulley
Note: Always trace the old belt's path or refer to markings before removal for accuracy.

Step-by-Step Installation Guide
- Step 1: Locate the belt tensioner
Identify the serpentine belt tensioner, typically on the front of the engine. Use a tensioner tool or wrench to rotate it clockwise, relieving belt tension.
- Step 2: Remove the old belt
Slide the old belt off the pulleys while holding the tensioner rotated. Note the routing sequence to avoid errors.
- Step 3: Install the new belt
Route the new belt according to the diagram above. Begin at the crankshaft pulley and follow the path precisely, ensuring the belt is seated correctly on all pulleys.
- Step 4: Tension the belt
Rotate the tensioner clockwise again to slacken, position the belt if needed, then slowly release to apply tension. Verify the belt sits flush with no twists.
- Step 5: Final checks
Reconnect the battery, start the engine, and inspect for smooth operation without squealing or slippage. Ensure all pulleys rotate freely with no misalignment.
Tip: Avoid over-tightening to prevent premature wear; refer to factory specifications for optimal tension.
