Tools:
- 10mm socket
- 15mm socket
-Breaker bar
-Flat-head screwdriver
-Timing light
Procedure:
1. Prepare the Vehicle:
- Park the Neon in a safe and level location.
- Engage the parking brake and turn off the engine.
- Allow the engine to cool down if it has been running.
- Disconnect the battery's negative terminal.
2. Locate the Timing Marks:
- Open the hood and locate the timing belt cover on the front of the engine.
- Remove the timing belt cover by removing the bolts holding it in place.
- You will now see the crankshaft timing mark on the crankshaft pulley and the camshaft timing mark on the camshaft gear.
3. Set Crankshaft Timing Mark:
- Using a 15mm socket and breaker bar, rotate the crankshaft until the "0" mark on the crankshaft pulley aligns with the timing pointer on the engine block.
4. Check camshaft timing mark:
- The camshaft timing mark should be aligned with the notch in front of the camshaft pulley
5. Ensure Piston Positioning:
- To confirm proper timing, remove the spark plug wire from the number 1 cylinder (usually marked as "1") and use a long flat-head screwdriver to insert through the spark plug hole.
- Slowly rotate the crankshaft using the crank bolt until you feel the piston at its highest point (TDC).
- Recheck if the timing marks are still aligned.
6. Set Ignition Timing:
- Reinstall the timing belt cover and connect the battery's negative terminal.
- Start the engine and let it run for a few minutes to warm up.
- Connect a timing light to the number 1 cylinder spark plug wire.
- Aim the timing light at the timing marks on the crankshaft pulley.
- Adjust the distributor (if equipped) or the timing adjustor (if electronic) until the timing mark aligns with the timing pointer.
7. Final Check:
- Once the timing is set correctly, turn off the engine and recheck the alignment of the timing marks.
8. Reassemble:
- Reinstall any removed components such as the timing belt cover and spark plug wires.
Note:
If the timing marks are significantly off or cannot be aligned properly, there might be an underlying mechanical issue that needs to be addressed. In this case, it is recommended to consult with a qualified mechanic or refer to the vehicle's service manual for further guidance.
