So I got a used inline pro kit last year, and had it installed around June. I had my first coolant line issue on the freeway when I was overheating (really bad, it was 1 or 2 ticks away from full on the stock water temp gauge). I had that line replaced, then I was leaking about 4 months later, and I had a shop replace the other lines. It is now April, and I am leaking yet again. I jacked my car up, hoping that the leaks where coming from any place other than the turbo coolant lines, only to find them both soaked. The heat wrapping that is on them is drenched with coolant. I was wondering what I needed in order to attempt to replace them myself? I do not have a lot of time to take it to the shop because I am still in school and finals are right around the corner. Any help would be greatly appreciated.

 

put hose clamps on the turbo side of the coolant lines

 

Are the lines getting too hot? Are they suitable for hot coolant?

I had rubber lines going to banjo bolts on the turbo. There were too close to the turbo and would deteriorate over time.

I fixed the problem by using extended fittings:


These move the rubber further away from the hot turbo and greatly extend the life.
