AISIN Engine Water Pump P/N:WPT-107
AISIN WPT-205 water pump for the 2016-2022 Toyota Prius 4-cylinder 1.8L and other vehicles circulates coolant through the engine. The AISIN water pump is an engine water pump assembly that is OE engineered and manufactured.
A coolant leak at the pump, a temperature gauge that climbs or a whine from the pump area can mean the pump is wearing out. These signs alone do not prove the pump is at fault, because a bad thermostat can overheat an engine too.
Besides the 2016-2022 Toyota Prius 4-cylinder 1.8L, this AISIN water pump for Toyota fits the 2020-2022 Toyota Corolla 4-cylinder 1.8L and the 2017-2022 Toyota Prius Prime 4-cylinder 1.8L, and each of these engines takes one pump. For another Toyota, look up your car in the "Vehicles it fits" section.
