Water Leak

[cnipp3173]

I have a water leak on the right rear under the plenium. How many water hoses are there and do i need to pull the plenium to replace them? Thanks

Definitely easiest to pull the plenum and replace the hose. I don't know how many you have because you haven't specified NA or TT. Check http://www.nicoclub.com/FSM/300zx/ for the FSM

Its a 1991 TT, I found all the info on pulling the plenium and doing the coolant bypass. If I get stuck I will post problem thanks!

Be prepared to buy new air and pcv hoses as well. Those things are probably like porcelain if they haven't been replaced and will either crack or leak. I would switch to silicone at the same time, last set you will have to buy. I would also plan on replacing the valve cover gaskets while I was in there. They are probably leaking as well. I get the new oem grommets for the screws and use a small amount of RTV on the bottom of the valve cover gasket, (not a bead, just a coating). The screws loosen up over time and can't be tightened with the plenum on. The rtv provides an additional seal for leaks.
