Note: using on the 3SGTE requires modification of the tensioner to allow for additional tension on the timing belt due to this pump's smaller drive pulley (one tooth smaller than the original 3SGTE pulley). It needs to have the holes slotted with a rat-tail file or similar operation to take up additional slack. Alternatively you could change the pulley to the 3S pulley, but you would lose the benefit of a faster spinning pulley.
Note: Will not work with Gen 3/4/5 3SGTE Oil pans.
Optional: Add an OEM front main seal and/or a gasket for the pump to mount to the block. These are OEM Toyota gaskets and seals.
