This is not a power steering pump for Tacoma 3.4L or 4runner. The printed side comes out the wrong way round. Not even suitable for Toyota with 3.4 liter engine. Very disappointed with this pump. After submitting the review I received an email from a gentleman named Jack explaining my problem as the description never stated that the product was not suitable for 3.4L. They basically corrected the description of the pump. . Jack was very helpful. Thanks Jack So I updated my review even though the part was wrong. They did their best to fix everything.
