Align the engine to Top Dead Center (TDC) by rotating the crankshaft.
Mark the position of the timing marks on the camshaft and crankshaft pulleys for reference.
Loosen the tensioner and remove the timing belt carefully, ensuring not to disturb the camshaft and crankshaft positions.

5. Install New Timing Belt

Place the new timing belt onto the camshaft and crankshaft pulleys, aligning it with the marks made earlier.
Reinstall the tensioner and adjust it according to specifications to ensure proper tension on the timing belt.
