The manufacturer recommends replacement of the timing belt (and water pump inspection) under normal operating conditions for CRV and Odyssey models every 84 months (7 years) or 105,000 (168,000 km). If the vehicle is operated in high temperatures (above 110°F or 43°C) or very low temperatures (below -20°F or -29°C) the timing belt should be replaced every 60,000 miles (100,000 km).
If, however, the timing belt is inspected earlier or more frequently than suggested, and shows signs of wear or defects, the belt should be replaced at that time.
