AISIN Engine Water Pump P/N:WPT-809
AISIN WPT-800 water pump for the 2000-2009 Toyota Tundra V8 4.7L and other vehicles circulates coolant through the engine. This engine water pump assembly is OE engineered and manufactured by AISIN.
Coolant seepage or crusty residue around the pump, or coolant loss with no other source, can mean the pump is failing. If the pump is the cause, this one replaces it. First look around it for stains with the engine off and cool; a shop can pressure-test the cooling system.
The 2003-2009 Toyota 4Runner V8 4.7L and the 2001-2009 Toyota Sequoia V8 4.7L are both fits for this water pump, along with other Toyota and Lexus models.
