How Long Can a Cracked Engine Belt Last?

[Bradley]

Engine belts with cracks need to be replaced promptly. Normally, belts should be replaced every three years or 40,000 kilometers. A broken engine timing belt can cause the engine to malfunction, severely affecting its performance, and may damage the valves and pistons. The steps for replacing a timing belt are as follows: 1. Remove the valve cover, detach the crankshaft pulley, and take off the timing chain cover; rotate the crankshaft to align the first cylinder at top dead center, then tighten the crankshaft fixing screw to secure it. 2. Rotate the intake and exhaust camshafts; there are grooves at the rear of the camshafts—align the grooves of both camshafts evenly and insert the specialized tool. 3. Remove the old chain and install the new one. The crankshaft pulley does not have a keyway; during installation, align the round hole on the pulley with the groove on the chain cover. 4. The crankshaft position sensor is adjustable—ensure the gap is properly adjusted during installation, otherwise it may trigger a fault code; both the crankshaft sprocket and pulley rotate freely.
