Default help me find my cooling leak

a few days ago my wrx started leaking coolant, the shop i took it to wanted a lot of money and said i would have to remove the turbo to fix the leak. i finally got around to poking around under the hood to try to find it today.

i couldn't pinpoint the leak. it was antifreeze, it smelled like it, and it was dripping slowly on the ground off of the passenger side crossmember under the car. there was a small bit of smoke from the area around the turbo, but all of the lines i could see were not smoking at all. what are the metal wrapped lines? i believe these are the oil lines, is that right? i traced all the coolant lines i could find from the top of the turbo, and there was no leakage or any buildup around the ends, but its leaking somewhere.

also, my heat isn't working, im guessing its because there isn't enough pressure build up to work the thermostat...

there is such a thing as a dye you add to your cooling system.
once its circulates, you take a black-lite and look for the coolant leak.

im sure if you stick your nose around that area(maybe use a mirror) you can find the leak

The metal wrapped line is a coolant line and your heat isn't working because you don't have enough water in the car.

the coolant is full, i filled it right before testing it. so i do have to take the turbo off to get to replace the line. i can't see the leak, but by process of elimination, thats the only line left. can i replace it with a standard heater hose?

Check where that wrapped line connects to the back of the block. I had the same dripping you do and that was my culprit.

Mine, yes. Literally the line I'm talking about is almost directly above the right side axle. Just get under the car and you'll be able to see what line I'm talking about.
