Coolant Leak !

Coolant leak found on pan under cylinder head dripping on header and manifold but no apparent leaks seen on valve cover seams. Coolant pool on frame under and on floor but no splashes on the front end to rule out water pump. Car was recently repaired for Turbo oil cooler leak 2 months ago. Appreciate the input for any other suspects and need to be well informed before getting raped by repair shops and technicians. Hoping its just the Coolant hose lines and nothing cylinder head related. Thank you .



Pictures are attached. Thank you for the help.

I had the same issue.
I replaced the black plastic "water pipe". I bought the pipe from Amazon I think and replaced it myself.
If you are handy you can tackle the job.
I can give you more info when I get home later if you're interested.

Here are some pics.
Only difficult part of removing the pipe assembly was to cut 1 hose clamp. They seal it from the factory. I used a sharp diagonal snip cutter to cut clamp. If you look at your car this clamp is sealed and no way to remove it but cut it out. Becareful when you cut this, take your time. I damaged one of the turbo hose. dealer does not sell that hose separately. I ended up buying iy from amazon, some one sells just the hose. That is pic#3.
This is pic#1.

Beside this, there's a hidden screw that's under the fluid container. You'll see it as you start moving screws.

Here's the link if you ever need that turbo hose.
Dealer sells the entire assembly and it's about $325.00.
If you not sure, buy the coolent pipe and take it to any shop. It's pretty easy job. You may need specific coolant for your model.\I will also link the coolant I use.
