Think I60 & R90
The best way to prevent costly system failure is to remember the Car Care Council’s recommendation. Start inspecting the serpentine, cooling and timing systems at 60K miles, and replace worn components by 90K miles or as advised by the manufacturer. When components wear, they put the entire system at risk. Combine belts and tensioners, water pumps and hoses, and use timing component kits for a complete system repair.
