Went and put a new water pump while it was somewhat easy to do. Actually getting to the water pump takes longer then replacing it. I didn't look far enough ahead to order new timing belt and belt tensioner. Since they only have about 25k on them from when this motor was put in the other 4runner I don't think they'll be an issue for some time. Water pump I order a AISIN pump for a 1993 2jz supra
