Hey guys big situation, and im hoping my motor is not blown .. but it sure sounds like a possibilty. I first was sitting with a cracked radator, then i purchased the KOYO unit, along with the AST, and new mazda hoses (upper and lower radator. So, today when i first start the car up after the installs, i burp the system plenty of times, and go for the full drive. I didnt even have the car fully warmed up yet, when i realize smoke is comming from a few areas, underneath the turbo, and behind the UIM, and it was enouigh smoke that is was seeping through the rats nest and the front of the IM. I look under the car, and there is a very decent size puddle of coolant, with more commin at a constant drip... any ideas as to what happend?

 

it's not the engine. if it was, it would idle REALLY rough and vibrate and shake.

sounds like a coolant hose has popped off or something. take off the UIM and look around.

 

Somehow, somewhere hoses are cracked. Search! (for the hoses), and you will find them. Easier would be get a pair of pliers, with a full system with an alright amount of pressure and squeeze the line to see if its leaking. The one behind the UIM sounds like its the coolant line that goes through the UIM. The turbo one, I have no idea since Im still having the same problem.
