ok tool time

this is a V4 motor but same exact part as V6

here's the valve



here's where it gets water from when it's under 3000 rpms



here's where it is going to under 3000 rpm



here's where it goes above 3000 rpm out to the pisser on the lower housing from the above pic



here it is under 3000



here's above 3000



first you need to remove below screws and nuts





then GENTLY pull out on the throttle arm till pin is out of the valve



now GENTLY pull out till accessible



now mark a location of the center part to out side so you replace correctly then pull out slide pin



then pull out the insert carefully



heres the valve taken out



clean this part very well



here's the inside of the valve with a seal in this ones case some have o-ring



you can grease the rubber seal if in good shape and then light grease on the valve and reinstall usually stops the leak.


or you can use the cap covers as below better to use the bypass system
