[RESOLVED] Coolant leak

[top_end95]

Well, as I was about to take the car out for a spin, I noticed a small puddle of coolant underneath the car. So, I pull the car back into the garage I wasn't really able to isolate the problem (still hot), but it looked like it was coming from the rear side of the engine. I am only able to drive the car on the weekends (car was sitting for about 2 weeks prior to this), but it didn't leak the last time I drove it.

What could be some of the culprits (besides a damaged hose)?

Coming from the rear I'd check around the heater core hoses and throttle body lines. No leaks on the cabin are there?

Thanks for the suggestions and no, I didn't notice any leaks in the cabin. I'll definitely check for the other things once the car is cool enough.

Well, it might have been one leak that looked as though it were two. I was on a slight incline, which would explain the "leak" towards the rear. However, I came across a thinker (at least for me it is ). When I noticed the first leak, it seemed as if it were coming from a turbo line, which at the moment I believed were the water lines (brain fart)... it ended up being the oil feed line. Now, the reason Im having trouble with this is that a small puddle of coolant was surrounding the oil feed on the turbo. I am aware of the water line on the backside of the turbo that passes over the oil feed line, but it does not pass over the actual turbo. I didn't observe any coolant spraying out of any lines. How would a puddle accumulate in this specific spot? Could it be coming up and out of the turbo itself? I will be attempting to replicate this problem tomorrow and will try to be more thorough in my findings.

Any further assistance would be greatly appreciated.

Make sure the car is level and most of the leaks I have encountered that are hard to find happen right at the hose clamp. Does your turbo use the coolant lines or is it just oil cooled? You may also want to check the radiator for a pin hole leak that may have sprayed the oil feed line to the turbo. Good luck!

Have you checked the O-ring by the water pump, I had a pretty nice size leak coming from there and it sounds like that is the general area the leak is coming from.

Thanks for the suggestions, fellas. Found the culprit. It was the hose that connects the back turbo water line to the thermostat housing. I'm just still a bit baffled how it managed to get on top of the turbo.

I'll be replacing that hose and will check for leaks again.
