Water Line To Turbo

[zero_apocalypt]

anyone else has ever been stuck with taking the last bolt on the water return line to get access to turbos. look at the attached pic and its number 3,

it wont budge. ive used WD40 thinking its rusted but no effect, the coolant has already been drained as well. any suggestions.. its on a r33 gtr hasnt been touched ever. also are there any kits to replace this line, i can only find water line kits from the turbo to the middle junction (number 4)

That line is pretty hard to get off. What I did is clamp down on the bracket that the line goes into with a pair of vice grip pliers and used a line wrench on the line itself. My R32 engine had some stuck lines too.

Are you using a decent quality line spanner/wrench?

hi yes i remember doing this on my r32 a while back number 3 was very dificult try leaving 2 and 4 connected and the bracket that holds number 4 into the head still connected is easier this way other wise the pipes twist and move too much and it can make it dificult to put back on. i tried using wd40 etc but the only thing that worked was some heat around the area of thread to my memory i even used a normal spanner to get it off after heat applied, before i applied heat i used a pipespanner (linewrench) it still didnt move carefull not to round bolt.
