I've had the MRX turbo kit installed for about a month now (by someone else), and today I smelled coolant and saw something was dripping. After getting under the car, I found a leak from where I think is coming out of the turbo.
Do I need to tighten the blue nut or the wider super flat nut that seems to be sandwiched against some copper?
Then, how the hell do I get to the blue fitting? Seems like I need some special tool? I don't think I could get it with an open ended wrench between the hose coming out of it and zero clearance around it.
