94svt50 Posted April 24, 2013 Share Posted April 24, 2013 I have a coolant leak that is coming from the gasket were some kind of coolant crossover pipe ties into back of passenger side head. Its not more then a slow seep and it looks about impossible to get to. I have heard that you have to drop the trans to reach it but, to me it looks like you could just pull the upper intake and worst case pull lower and valve cover to reach it. Any one have any experience with this leak or have a coolant schematic diagram they could post up? Thanks for any info on this 2002 v6 w/176k miles Link to comment Share on other sites More sharing options...
Towncivilian Posted April 24, 2013 Share Posted April 24, 2013 (edited) Could you try to get a picture of the leaking part? It could be the water control valve or its gasket. If it is, it's accessible without pulling the trans, but you will need to pull the intake manifolds and fuel rail if I recall correctly. Has the coolant ever been changed?

94svt50 Posted April 24, 2013 Author Share Posted April 24, 2013 (edited) The gasket I need is part # 11062 <img src="http://ocnissanirvineparts.com/nissanImages/R50/210B%2001.jpg" border="0" alt=""> Coolant was changed about a year ago. I assume if I can access the water valve then I should also be able to access this gasket through removing intake manifolds.

mel.d Posted May 6, 2013 Share Posted May 6, 2013 I had the same leak. It was running down the back of the motor and dripping from the bell housing. Turns out the passenger side gasket of the crossover pipe was the culprit. It was a PAIN IN THE A$$ to replace, but it is doable. You have to remove the intake plenum to gain access, but the location is so close to the firewall that it leaves little room to work with. I replaced both gaskets on the crossover pipe as well as the second thermostat that connects in the middle of the crossover pipe. Your back will not like you afterwards.
