On the way to work, I stopped at a stop sign and saw steam coming from under the hood, low coolant light went off shortly after. I stopped and steam is pouring out underneath the intake tubes (some coolant actually on top of the tubes). I plan on having the car towed home. I haven't had a chance to look at it closer. Anybody have any idea where the leak maybe coming from? Coolant hose to the turbos?

Thanks!

 

im gonna have to go with heater hose for 200 pat.

 

I would say that it's either the upper hose that goes from the radiator to the filler neck, or your water pump went bad and is spraying on the pulleys and going everywhere.

 

turbo coolant line

 

I would say maybe uper heater hose or water pump has craped out too.

 

Did you get a ton of steam?

 

Got a good amount of steam, but it seemed to be from coolant leaking onto something hot, not tons and tons of steam.

 

There are 5 different hoses in that location, upper rad, lower rad, turbo inlet, turbo outlet, and water pump to heater hard pipe. You won't know 'till you rip into it! SOOO much fun dealing with coolant issues!

 

If you want to start ruleing things out then put some more coolant into it and start the car and look under the hood....take out the intake so you can see everything, if coolant doesn't start streaming out of the water pump then you know thats not it. or you could just get a pressure tester and pump, pump, pump it up!

 

I 2nd that...... they need to be changed every 10 - 15k according to Mazdatrix

 

Finally started diagnosing what the problem was, and quickly found that the waterpump to turbo coolant line had a HUGE rip in it. Heat soak musta been extreme, take a look at the hose!

 

yep... I remember replacing all of those.. while your in there you might want to replace the other turbo coolant hose as well. It is by the hard lines for the precontrol/wastegate actuators.

 

Mine looked JUST like that when it went. Replace both.

 

I just ordered both turbo lines from a local Mazda dealer, I replaced the cracked one with Goodyear fuel line of approximately the same diameter and length in the meantime. Anybody know if the fuel line will hold up?

Thanks!
