1. Camshaft Sprocket Timing Marks:
- There is usually a small dot or notch on the camshaft sprocket.
- This mark should align with a similar dot or notch on the cylinder head.
- This ensures that the camshaft is in the correct position relative to the crankshaft.
2. Crankshaft Pulley Timing Mark:
- The crankshaft pulley has a notch or mark near its circumference.
- When the engine is at Top Dead Center (TDC) on the compression stroke for cylinder number 1, this mark should be aligned with a fixed pointer or mark on the engine block or timing cover.
3. Timing Chain Marks:
- The timing chain has colored links or marks at specific intervals.
- These marks should align with corresponding marks on the camshaft and crankshaft sprockets.
- The alignment of these marks ensures that the timing chain is correctly installed and that the engine is in the proper timing.
It is important to refer to the specific vehicle's service manual or Haynes repair manual for the exact timing marks and instructions related to your specific Nissan 2.4 engine. These marks are crucial in ensuring proper engine operation, performance, and fuel efficiency.
