Is it spraying out of the waterpump?

[Sideways_blksr20]

Yeah ....

Not to insult your intelligence, but you did use gasket maker to seal it up correct? Where exactly is the water spraying out of?

Yeah there's no oblong bolt hole in you block BUT that the upgraded N1 water pump has one, and it open to your cooling system. you'll have to weld it or seal it up.. its common

Yeah i did bro but ididnt know u were supposed to weld that hole ...

[Chrischeezer]

I wouldn't do this but...

I have read that most ppl fill the whole with silicone as its a very small part not sealed.

read up on it,

its gross but it works

[Sideways_blksr20]

So i dontneed to remove the whole pump ? Just fill the hole with rtv and put back the bolt with a washer ?

[silver350z05rb]

yea its common like they said, i have heard of doing both, silicone the shit out of it or weld it as well, i would assume welding it shut would be better?correct? i mean im sure its about than $10 bucks for someone to weld that for you. or Free if you have a machine.

[Sideways_blksr20]

So should i just remove the one bolt fill it up with rtv and put back the bolt with a washer?

[mattack69]

Weld this, do it right the first time. Those aren't cheap if they fail.

[Sideways_blksr20]

So weld it an redrill it ?

[mattack69]

Have it welded then retap yes. That's my vote at least. Should be fairly easy :)

i had 2 rb26 with N1 pump !!!! all my bolt were in place except for that one your talking about !!! put alot of RTV in the oval hole and insert bolt bolt with washer !!!

never leaked any coolant


i used the orange RTV that came in my rebuilt gasket kit !!!

If you dont want to remove the pump ! Make sure you dry everything cause the Rtv wont stick good

[Chrischeezer]

use "Ultra Gray" silicone too.. it dries much harder.

just bragging : my R34 engine doesn't have this problem
