I just installed one of these on our 2003 Camry. The car has 175000km. I replaced the OEM belt with a Gates K070763 at 75,000 miles and replaced that belt with another Gates K070763. According to the Gates Wear Scale, the Gates 100,000 mile belt was still in very good condition, showing no age cracks or other imperfections. I changed the belt as a simple preventive measure as my granddaughter now owns the car.
