Gts25t Water Leak At Steel Junction Fitting .

[discopotato03]

Hi all , I found a pin hole water leak at the steel fitting below the back of the inlet manifold . Its right below where the rubber water hose runs upwards and forwards to the back of the throttle body .

Does anyone know if this part is available in Aus and how difficult it is to change it . Looks like a mongrel of a job with possibly the inlet manifold removed .

Probably time to change all those original rubber hoses down there as well .

Thanks in advance cheers Adrian .

To give a better description its the four way tubular steel junction above the starter motor .

More researching this pipe union is called "Pipe assembly , heater feed" .

From the R33 RB25DET cooling system diagram the part no is 14075N which translates to OEM Pn 1405321U00 .

When I read it i thought what a bugger of a job that would be!!!

Then I thought probably happen to me now..........what is once seen cannot be unseen! Can't help with the part sorry Adrian, but I'm sure if its not available via Nissan that someone like Pirtek or a good heavy machinery hydraulic shop could make it up. They usually have all sorts of benders flares, and TIG welders for stainless steel pipe and such.

Im sure i got one of them when i built my engine. Have you tried Amayama? If you have the part number, a call to your local Nissan will soon give you an answer also

what engine? I've got at least one spare for an rb26. Even if not I think you can find them second hand, they are often removed when cooling systems are modifiied

Rockdale Nissan Sydney kindly got me a new one ex Japan .

Now on a mission to get a full set of genuine water hoses for everything under the inlet manifold and change everything at the same time . I figure they are 20 yrs old and living on borrowed time . Hate water leaks in hard to get at places . Also doing the heater hoses and the plastic joiner gadget on the firewall .

Can anyone help me out with part numbers for the oil heat exchanger water hoses plz .

Cheers Adrian .

Replace the hose coupling on the firewall as soon as you can. The two made of plastic. When they get old they don't leak, they explode. And because the water disappears so fast the temperature gauge doesn't have time to register the skyrocketing temperature. You look at the gauge and it seems fine because only measuring air temperature. Result ? Kboom !

Just off the phone to Rockdale Nissan spares and they have everything , mostly ex Japan , to pick up .

To replace every heater hose inc the plastic junction , every hose and pipe under the inlet manifold inc all block fittings costs about a grand .

Some of these bits are discontinued and if lucky old stock available .

I will be using whatever coolant they recommend because they know their metallurgy best and what green blood works reliably .

I had an old Subaru L Series RX Turbo a while back and that car tried to kill itself with coolant leaks a dozen times . Too many hoses in really awkward places to get at . Water leaks kill engines so cooling systems must be reliable .
