AISIN Engine Oil Pump P/N:OPT-021
AISIN OPT-022 oil pump for the 1995-2004 Toyota Tacoma V6 3.4L and other vehicles pumps oil through the engine. Also called an engine oil pump, it is OE engineered and manufactured.
A low oil pressure warning light or new engine noise can mean the oil pump is worn, though other oil-system faults can show the same thing. Before you replace the pump, rule out a low oil level, checked with the engine off and cool, and a faulty pressure sensor or a clogged filter.
It is also an oil pump for the 2000-2004 Toyota Tundra V6 3.4L and fits the 1996-2002 Toyota 4Runner V6 3.4L.
