RB26 Coolant Leak & Part info request

RB26 Coolant Leak

Noticed temp getting near 100c so I shut down. Noticed a leak. After cooling I filled it up and squeezed pipes and found where its coming from. Anyone know the part number by chance? When I do squeeze it comes out the back of the metal pipe. It squirts straight so its a decent hole and not from the hose being loose. Its at the back of the block next to the firewall. Any help is greatly appreciated. -Dave

well done to have a keen eye on the gauge, lots of people don't notice until it's too late.

while those hoses seem to often be the first ones to go, everything will be a bit old and brittle by now.  why not do a full hose replacement kit like this one for fun over the break, or even better give the car and kit to a mechanic in january  http://justjap.com/jjr-silicone-engine-heater-hose-set-nissan-rb26dett-r32-gtr-blue.html

Who sells the coolant bypass pipe for the rb26?

I will get the kit I found on the japan yahoo auctions and probably do what I can. I have access to a lift(hoist) and many tools. Definitely going to get a new radiator as mine is pretty rusty looking on the inside. I should've swapped it when I got the car. Wish I had the extra cash to drop it off somewhere. Bet this job will be a pain.

Thats the one. In the factory service manual it is called the water bypass connector

Was thinking this one, water bypass connector.

What did you do to yours? The part number is 14075-05U00- and the place to buy it from is Amayama

[dave5678]

How do I remove 14498-05U14 please? I dug through the manual but didn't find anything. Do I start by removing the bolts on this end(in attached image)? Kind of lost since I was unable to source the replacement yet but would at least like to do the first part while I wait. I am going to use Amayama since no shops in Japan could get it for me. Thank you!

Feels like its going to snap when I use a wrench on the above pipes. Do they screw right off?

[Duncan]

Yes they do screw right off, but they can also seize over time and when they do they can twist until they break instead of undoing.

Try a little wd40 over a couple of days, and use a flare nut spanner if you can.

But odds are it's going to break and you'll need to replace it.

[dave5678]

Ok. Used some liquid wrench on them. Hoping for the best. Thanks for the help!
