Belt Routing (2.0L Naturally Aspirated Engine)

Before you begin, it's highly recommended to take a clear photograph of the existing serpentine belt routing. This will serve as an invaluable reference during reinstallation.

The serpentine belt on the 2019 Honda Civic with the 2.0L naturally aspirated engine typically follows this path:

1. Starting from the crankshaft pulley at the bottom.
2. The belt then goes up to the A/C compressor pulley.
3. From the A/C compressor, it will route around the smooth idler pulley.
4. Next, it travels to the alternator pulley.
5. The belt then wraps around the water pump pulley.
6. Finally, it goes around the serpentine belt tensioner pulley.

Note: The 1.5L Turbocharged engine may have a different routing due to variations in accessory placement. Always consult your vehicle's service manual or a reliable diagram for your specific engine.

Belt Routing (1.5L Turbocharged Engine)

As with the 2.0L engine, always photograph your existing belt routing before removal.

The serpentine belt on the 2019 Honda Civic with the 1.5L turbocharged engine generally follows this routing:

1. Beginning at the crankshaft pulley.
2. The belt then goes up to the A/C compressor pulley.
3. From there, it might pass over an idler pulley.
4. It then routes to the alternator pulley.
5. Next, it wraps around the water pump pulley.
6. Finally, the belt engages the serpentine belt tensioner pulley.

Note: Minor variations can exist. Always double-check your specific engine for the precise routing.

How to Replace the Serpentine Belt

Replacing the serpentine belt on your 2019 Honda Civic is a manageable task for the DIY enthusiast. You'll typically need a serpentine belt tool or a 3/8-inch breaker bar to release the tension on the automatic tensioner.

1. Safety First: Ensure the engine is off and cool. Disconnect the negative battery terminal for added safety.
2. Document Routing: Take that photograph you thought about earlier! It's crucial.
3. Relieve Tension: Locate the automatic belt tensioner. Insert your serpentine belt tool or 3/8-inch breaker bar into the square drive opening on the tensioner and rotate it to release the belt tension. Hold it in this position.
4. Remove Old Belt: While holding the tensioner in the released position, carefully slip the old serpentine belt off one of the pulleys (usually the smooth idler pulley is easiest).
5. Inspect Pulleys: With the belt off, inspect all pulleys for any signs of wear, wobbling, or excessive play. Spin them by hand to check for noise or resistance. If any pulley feels rough or noisy, it likely needs replacement.
6. Route New Belt: Using your photograph and the routing description, carefully route the new belt around all pulleys, leaving one pulley (again, often the idler) off so you can easily slip it on last.
7. Final Installation: Apply tension to the tensioner again with your tool. Slip the belt over the last pulley. Slowly release the tensioner, ensuring the belt is properly seated in all grooves on all pulleys.
8. Double-Check: Once the belt is fully installed, visually inspect its entire path to confirm it's correctly aligned and seated.
9. Reconnect Battery: Reconnect the negative battery terminal.
10. Test: Start the engine and listen for any abnormal noises. Let it run for a few minutes and re-check the belt
