I somehow got a pinhole on the coolant feed pipe that feeds coolant to the turbo. Is there a way to replace the coolant pipe without removing the heatshields, dropping the downpipe and removing the manifold? It's this pipe for reference.

 

 

Lol I already bought the pipe, but I was considering just sleeving the pipe with a coolant hose and clamping down on it haha

 

Do it once and do it right!

I havent needed to pull it off while still on the car but I feel like you should be able to get it it with minimal work. The only thing holding it on is the banjo that connects to the turbo and one of those lil tabs that holds it to the compressor cover. Of course you gotta remove the robber hose that goes it it too. But I feel like you may be able to snake it out. Good luck!

 

With the manifold/downpipe in the car, access is restricted. I can see it, but there's no way a wrench would fit in there. Potentially a socket but all of the angles I have tried have failed. I think I'll try to remove the downpipe heatshield next and sneak a socket in there but after that I'm likely just taking the turbo off the car over the weekend.

Anyone have a mitsu manual pdf available?

 

Removing the heat shield should give you plenty of access.

 

Are you saying that the lower heat shield for the O2 housing is blocking access? I havent had a stock o2 housing on my car in years so I guess its easier for me to say just snake it out of there. But Im thinking if you can pull that off it should be easier. Also depends on what tools you have at your disposal as something like a swivel socket or perhaps a crows foot could make all the difference. Good luck!

 

Yeah the lower heat shield for the O2 housing on the downpipe. I wanted the PDF to find the bolts holding it in, I removed the bolts on top in hopes of it flexing enough out of the way, but it hasn't. As for the wrench not being a viable option, it's not the clearance from the heatshield that is the issue there, it is the fact that the banjo bolt offers literally 3mm of clearance to the cold side turbine. A wrench wouldn't fit in that 3mm gap while being able to turn lol. I'll jack up the front of the car on the weekend and see what I can do/find. I may just end up putting a dremel/grinder to the heat shield as a hail mary.

 

Replaced it without dropping the turbo 2 months later (I've been busy). For anyone that comes across this thread, you only have to undo the top 2 bolts on the downpipe heat shield and bend it out of the way.

The things that i removed were:
intake pipe from turbo cold side (for clearance)
upper radiator hose (big one right by the rad fill)
coolant/air pipes near the intake

Once I gained enough clearance to unclamp the rubber water hose and undo the 10mm bolt that holds the pipe to the turbo, I was pretty much home free. I bent the downpipe heatshield towards the passenger side, put a 22mm socket onto the banjo bolt and it came off. Aligning the two crush washers for reinstall was kind of a pain since I couldn't see, but I got it on within 5 minutes. Now to put this thing back together after losing a bolt (I knocked over the container holding all the fasteners I took off FML).
