AISIN Engine Water Pump P/N:WPZ-743
AISIN WPZ-045 water pump for the 2013-2016 Mazda CX-5 4-cylinder 2.0L, the 2014-2025 CX-5 4-cylinder 2.5L and other vehicles circulates coolant through the engine. This AISIN water pump is OE engineered and manufactured by the number one original equipment water pump manufacturer in the world.
A coolant leak, a whining or grinding noise from the engine, or an engine that runs hot can mean the water pump is wearing out. Before you replace the pump, rule out a leaking hose, a stuck thermostat or a cooling fan problem, because the pump may not be the one at fault.
This is a direct-fit water pump replacement for the 2013-2016 Mazda CX-5 4-cylinder 2.0L and the 2014-2025 CX-5 4-cylinder 2.5L, and a water pump for the 2016-2023 Mazda CX-9 4-cylinder 2.5L; each of those engines takes one pump. If you drive a different Mazda or a Toyota, look up your own car's year and engine in the "Vehicles it fits" section.
