AISIN Engine Water Pump P/N:WPT-048
AISIN WPT-169 water pump for the 2011-2014 Toyota Tundra V6 4.0L and other vehicles circulates coolant through the engine. This engine water pump is OE engineered and manufactured by AISIN.
A coolant leak near the front of the engine, a whining or grinding noise, or an engine that runs hot can mean a water pump is wearing out. Before you replace the pump, rule out a leaking hose, a loose clamp or a thermostat that sticks, since a problem there can look like a pump failure.
For Toyota 4Runner water pump replacement, it fits the 2010-2024 V6 4.0L. It also fits the 2011-2014 Toyota Tundra V6 4.0L and the 2010-2014 Toyota FJ Cruiser V6 4.0L. The 2010-2024 Toyota 4Runner V6 4.0L takes one pump, and so do the other two.
