What would you do? Re:Coolant leak.

[stipro]

Ok, so Iam a day or so away from turning the key, I have just put in a TD05-16G, twin turbo coolant tank, and a wrx intercooler.

With everything bolted up, I did a pressure test on the coolant system, because I moved some plumbing around for the coolant tank. Whats that hissing I say so to myself, oh easy fix lower coolant line on the turbo. Fixed that.

I pressure it up again, more hissing. Hit the main coolant lines/passages with a soapy solution, and I found the leak.
Its on the main coolant tube that bolts to the block on the drives side.(underneath the intake manifold )

So as the question as in the title returns, what would you do?

Its not a big leak and I havent touched anything in that area, so I am guessing that it was there before I started. But there was no coolant leak at that location.

I have had the car off the road for a week and a bit now, so I thought that without coolant at that point of the system the seal is drying up .

Tearing it all apart in my driveway is not realistic right now. So do I fill the system up and see what happens? Fix it later?

I dont know. Help me make up my mind.

I think you need to fix it. What would ignoring the problem now accomplish? At best, you'll have to pull stuff apart again to do the repair when it becomes absolutely necessary. And at worst, you could get stranded on the side of the road and/or damage the engine.

Figure out where exactly the leak is. It sounds like you're talking about where the 15mm heater hose attaches to the water manifold? Unless there's a crack in the metal, that's gotta just be a bad hose or clamp, right?

Or is it just coming from that area? It's possible that an o-ring between the water manifold and block is leaking.

Or are you talking about the 11.5mm plumbing for the turbo? I'm guessing not because you mention installing a new coolant filler tank but say you haven't touched the part that's leaking.

At least its accessable to fix without having to pull the motor. My oil leak is coming from the rear of the engine probably due to the rear crank or the plate...and this is on NEW gaskets! So my vote is to get to it as soon as you can, so you don't have to be stuck on the side of the road somewhere as vrg3 mentioned.

Yeah Iam going to fix it. I ordered the parts today. Its the o-ring for the water pipe that bolts to the block on the drivers side, so changing them both is a great idea. I am going to start taking the intake manifold off tonight. It wasn't really a question of "will I or wont I", I guess, it only makes sense to fix a problem when it is minor, and not wait until its major.

Im just getting so anxious to turn the key and go for a drive with the new turbo and intercooler.
