    I was told that the water pump should be replaced every 80 thousand miles is this true? 2015 with 86k on it. How about belts for the fan water pump etc and the hoses from the radiator after 5yrs of highway travel should they be replaced? Anything else that after 5 yrs should be looked at?

    There are no belts and I would not bother to replace a water pump just because the car has 80k miles on it. Hoses either. There are probly some fluids that could be changed......

    One Prius maintenance expert whose article I read firmly recommended 120K for the water pump replacement. Since I had just passed that mileage, and I now consider my 2012 Prius V (124K miles) a 10 year-old vehicle, and I live in Las Vegas with 100-115 outside air temperatures, I was seriously considering it. Then last weekend, I saw a coolant temperature light come on for about 5 seconds then go off. No other indications of trouble. So this week I decided to have a local shop replace the engine coolant pump, thermostat, and inverter coolant pump. Here is the photo of the old engine coolant pump. Note the cracked plastic covering on the rotor. The engine coolant pump was indeed going to fail soon and I am glad I got it replaced before it did.
