Rb20 Rad Hose Close To Exploding

[freyb]

im having a hard time figuring out how to remove the small hose . removing the clamps simply wont do it. the metal cylindrical object (dont know what its called) is somewhat fixed and has a metal piping going underneath the plenum. when i traced the pipe. i found its bolted with 2 bolts under the plenum but one of them is right beside the metal piping which is connected from the thermostat or lower rad hose piping connection. do i have to remove the whole plenum or can i just remove the 2 bolts underneath the plenum(which i think is very tight spot to reach and close to impossible to unscrew )? or remove the piping for the thermostat, does that need a gasket btw if ever i remove that, would the high temp silicon gasket maker work? . need help my hose will blow pretty soon...

That pipe runs the whole plenum it's bolted in 3 locations. You need to remove that pipe to remove the hose

it's not going to explode, it looks like it's just a bit long so it is bowed out

being so short it will be stronger and less likely to explode than a longer hose

unless it is leaking or you plan to change all of the hoses around there (because getting that metal line off that runs under the plenum is a flamin mongrel job that pretty much requires the plenum to be removed) then it will be fine

i would like to replace it because theres some stuff (corrosion?) thats coming out on the left side. im not sure what that is. and its getting a big bigger now.

Pull the eniter plenum off it will make life easier replace everything while you have it off

[mystery_kid]

yeh replace all of the hoses that run under around the the plenum, there is about 7 or 8 of them if you are going to take the plenum off

order them from nissan because they are moulded so you can't get them from anywhere else. they will cost about $300 all up (without heater hoses) and use new hose clamps

it is something you will do once in the time you have the car but it gives good peice of mind

you will tear your f**king hair out trying to get that hard line off that connects to the metal cylinder without taking the plenum off, it's pretty much impossible

thanks for the replies. sound like its gonna be hard.. no other way but to remove the whole plenum?

You can but it is easier to remove

dam RB20,

so much work just to replace a hose,

better off ripping the entire motor out and putting in a 25!

Calm down now mate haha

you could... if you have the patience to jam your arm in under the plenum without being able to see what you are doing and get the pipe off

if you take the starter motor out you can get 1 arm up from the bottom too

so much hassle and swear and rage

so much hassle to replace a single hose...

still looks impossible to unscrew the water pipe underneath the plenum. its right next to the engine block where the thermostat is..
