Ok here are the pics. Please let me know what each one of the hoses I labeled carry oil or water. I know what some do. Im going nuts looking for this, it looks like its coming from INSIDE the turbos. Picture 3 shows some coolant. Also the last pic, you notice the oil is extremly shiny, thats from the steam of the coolant reacting with the oil. Any tips would be apprecaited. Looks like I got to take the turbos off huh???

 

Which color?

 

Your numbers are all f^ck^d up

Pic #1:
A & B are both coolant.

Pic #2:
A & C are your turbo coolant hoses.
B is your turbo oil line.

Pic #3:
I have no idea WTF that is or where you even took the picture from.

Pic #4 & #5:
A in both pictures are your oil return lines from the turbo's.

Pic #6:
B is a coolant heater hose (I think) , A is yet to be determined.

 

A- oil

B- coolant

C- coolant

 

That seems right, now my problem is finding this leak!? For A & B would I have to remove the turbos to get to them? Looks like I may have to remove the turbo's anyways just to find the dam leak. Any tips, here are the symptoms, theres steam coming from the turbo area. Then I look around over / and under from over I see steam, and from under I see coolant leaking around (pic 3), could the turbo's have cracked from the inside? That would really suck .

 

turbo coolant lines are prone to failure (think extreme heat). Don't know if that's your problem, but they should be replaced every 2-3 years.

 

Could anyone give me a pic of turbo coolant lines then. Because if its not of the above ones Im guessing I will have to remove the turbo's to get to them huh?

 

I got turbo coolant banjo bolt that loosen over time(<1year).
I basically have to take off the turbo, and tighten these. There are 4 of them.
2 on the engine side(input), 2 on downpipe side(covered by heatshield, the output).

Don't have pictures, but you have to take the turbo off to access and see them anyway.

Oh yea...you can take off the airpump and see the hoses that goes from waterpump to both lines.

abbccaaa

 

Pic 1 is sorta a zoom in of pic 2 which is behind the airpump (which I removed). So it looks like I have to remove the turbos huh =/. Oh well. Anyone else got some more tips?? Can I remove the turbo's with the engine in the car?

 

Fatman0203, good pics. Since there was no final answer to this thread I am going to add my 2 cents and similar experience. My steam/coolant leak problem was the turbo coolant hoses.
My symptoms were: after my 7 warmed up after driving a few miles, some steam would come from under the hood sometimes. But then the steam would stop after a while. Closer inspection showed steam coming from the passenger side of engine, somewhere around the turbos. The coolant level was fine everytime I checked it. Never saw coolant puddles or coolant dripping from under the car, just steam - sometimes. I replaced both turbo coolant hoses and solved the problem, no more steam. The hoses were very hard, and bloated as mentioned above. The hoses had a small leak at the hose clamps. These hoses are know to fail because of the heat from the turbos.
You do not have to remove the turbos to replace these 2 hoses. I HIGHLY recommend that you buy a pair of long-handled (8") angled needle-nose pliers to remove the lower hose clamp.
I bought OEM hoses from Mazdaformance (http://www.mazdaformance.com).
N3A1-13-54X $8, N3A1-13-536 $4

Hope you solved your problem, let us know what the final solution was.

 

I would get a radiator pressure tester or make one with a tire pump. Use it along with anything else you need. A good light and mirror, along with a diagram of the coolant flow. I would not start tearing down anything before you know where the leak is. The areas which house coolant, hoses, pipes etc should be targeted so they can be viewed. If you check all the ones you can see move on to the ones you have trouble seeing. That will narrow the chances of screwing up and fixing something thats not damaged or missing a second leak. P.S. clean the engine up and you will be able to track the coolant easier.

 

I need pics, Ive gone over the Service Manual a few times, and unless their very well hidden I honestly can not find them. The steam comes out more from the primary. As you can tell by the pics Ive been over and under a bunch of times and still nothing *sigh*

I dont want to tear anything down but Im having such a mission finding this leak. I plan to get a proper tester since I still can not find it. I will try to clean up the engine bay a bit but looks like I may have a tiny oil drip or something somewhere.

 

Ok heres something that would help me out alot. How many hoses with coolant run to the turbos in total. Coolant only. And are they all rubber?

 

coolant is flammable, becareful of fires...

 

There are two coolant hoses. Both are rubber. One is L shaped and about 4 inches long. The other has a slight bend at one end and is about 5 inches long. Both have an addional rubber shield around them for protection. I have two brand new ones in my hands right now, waiting to go in.

IIRC, both can be replaced fairly easily (just removing intake piping). Just go ahead and order them from Malloy Mazda and replace them. They are too important to skimp on.

See page C-28 in the Workshop Manual for a diagram showing both.
