On models through 1989, Honda does not specify a recommended inspection or replacement interval. However, since these engines utilize an interference design, it is highly recommended to at least inspect the timing belt at 60,000 mile (96,000 km) intervals. It is an even better idea to replace the belt at these intervals. On 1990-94 models, Honda recommends the timing belt to be replaced at 90,000 mile (144,000 km) intervals. On 1995 models, the recommended interval is 60,000 miles (96,000 km).
Replacing the timing belt before its recommended interval is a wise choice. It is far less expensive to replace the belt than to repair the engine damage which results from the belt breaking.
When checking the belt, inspect for cracks, missing teeth and wear on any of the surfaces. Inspect the sprockets for grease and other deposits. If any of these conditions exist, the belt should be replaced. Please refer to Engine & Engine Overhaul for procedures on timing belt removal and installation.
