MY1PATH Posted December 22, 2010 Share Posted December 22, 2010 I do it every timing belt. Belts gotta come off anyway to remove the 4x4 water pumps. Link to comment Share on other sites More sharing options...
keelhaul Posted December 22, 2010 Share Posted December 22, 2010 (edited) The water pump is gear driven on the vq35. Since it seems quite difficult to change I would leae it alone until it fails.. Edited December 22, 2010 by keelhaul Link to comment Share on other sites More sharing options...
pathfounder Posted December 22, 2010 Share Posted December 22, 2010 I do it every timing belt. Belts gotta come off anyway to remove the 4x4 water pumps. The opposite is also true. If the pump needs replaced, do the timing belt also. I have no opinion on gear-driven pumps. I guess I would replace it once I could hear it.

NOCOjay Posted August 26, 2014 Share Posted August 26, 2014 ITs been a few years since this was posted... Has anyone had to deal with this? I am prepping to do a big round of preventive maintenance to the pathy and this is something that I am curious about.... I did some searching and no one seems to know whats up w/ the 3.5 water pump. My rig is at 185K and running strong. I would like to get to 250k.... Thanks! Link to comment Share on other sites More sharing options...
Rebelord Posted August 26, 2014 Share Posted August 26, 2014 If it ain't broke. Don't touch it. Pretty much with that one. Unless its failing. No need to mess with it. Unless you are opening it to adjust timing chain slack. But that is a very noticeable noise. Link to comment Share on other sites More sharing options...
Precise1 Posted August 27, 2014 Share Posted August 27, 2014 ^This! Run it until it leaks or you have to take it off for some other reason. B Link to comment Share on other sites More sharing options...
