How do you remove the coolant heat storage tank and heated coolant pump in a Toyota Prius?

To remove the coolant reservoir, first disconnect the cable from the negative terminal of the auxiliary 12-volt battery and remove the cover from the top of the radiator. Then, raise the vehicle and remove both engine lower covers, the front bumper cover, and the left inner wheel well liner. After the reservoir has cooled, drain it and disconnect the hoses and wiring connectors. Support the reservoir and remove the nut and four bolts securing it before separating the hooks and lifting the reservoir from the vehicle. To remove the heated coolant pump, clamp off the hoses and disconnect them from the pump after raising the vehicle and removing the left engine lower cover and inner wheel well liner. Disconnect the wiring and remove the bolt before detaching the pump. When installing both components, refill the cooling system through the reservoir and bleed out any trapped air.

Toyota Prius Coolant Reservoir

The Toyota Prius coolant reservoir now and then known as the coolant recovery tank is another extremely important component in the car's cooling systems that stores extra coolant in order to avoid it spilling or air entering the system. There are two main types of Coolant Reservoirs used in Prius vehicles: and two types of the tank as the overflow tank systems and expansion tank systems. Overflow has just a simple and cheap plastic cap and coolant can be forwarded from the radiator to the recovery tank if pressure is beyond the capacity of the cap with the help of overflow system, whereas in the expansion system the tank is pressurized and made up of a heavier cheap plastic in which air is released if pressure is too high. A guide is advised to take time often to inspect the Coolant Reservoir so as to confirm it is in good shape and not leaking or cracked.
