AISIN Engine Water Pump P/N:WPF-002
AISIN WPF-023 water pump for the 2002-2005 Subaru Impreza H4 2.0L, the 2004-2014 Impreza H4 2.5L and other vehicles circulates coolant through the engine to carry heat away. This engine water pump is OE engineered and manufactured.
A coolant leak at the pump or a temperature gauge that climbs can mean the pump is wearing out. Before you replace it, rule out a leaking hose, a faulty thermostat or a low coolant level (checked with the engine cool), since each of those can also run the engine hot. The engine has one water pump position, so this listing is the one pump it takes.
This water pump assembly fits the 2005-2009 Subaru Outback H4 2.5L and the 2004-2007 Subaru Forester H4 2.5L. If your Subaru is not named here, look up its year and engine in the "Vehicles it fits" section.

Will this Subaru Forester water pump fit the 2004-2007 Forester H4 2.5L?

What is the AISIN WPF-023 water pump made of?

Can overheating or a coolant leak mean this water pump has failed?
Yes, a coolant leak at the pump or a temperature gauge that climbs can be signs of a worn water pump. Look for leaks only with the engine off and cool.
Is the AISIN WPF-023 an OE water pump?
Yes. The AISIN WPF-023 is OE engineered and manufactured, and AISIN is an original equipment water pump manufacturer.
