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. 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.
The OEM pump is made for toyota by Aisin. This pump is available also as an Aisin part for significantly less than the Toyota price, yet is the identical manufacturer pump. The only differece is the box it comes in, and Aisin is apparently required to grind the "TOYOTA" lettering off of the pump. Select which name you want on the outside of the box below.
