Alright everyone, just want to say what's up. This is my first post on here. This place is great as I've learned so much you guys. There's an insane amount of knowledge here. Anyways now to my problem. I have a coolant leak which seems to be coming from above the front rotor housing. There's traces of coolant all over the wiring harness and bracket that runs through that area and there's also a puddle of it that has collected at top of the housing where the Mazda stamp is. Best part is that it even ran down both sides of the front rotor housing where it meets the irons but it never hit the ground. I have done the TB bypass and I have double and triple checked the connections made and nothing is leaking there. My coolant reservoir is always full which leads me to believe that the leak is small. I just noticed it yesterday when removing my coils. I spent quite a while digging through all the lines that run behind the alternator and I can't find anything leaking. I cleaned all the dried coolant up, but won't I won't be able to start the car and test anything out until my harness comes in for my custom yukon coil setup. Anyone else dealt with anything like this? By the way I have an '05 6MT with 34K, car idles fine, starts fine cold and hot, no other problems. I appreciate any help.

The TB bypass is a huge clue, triple check it.

There's not much else that can leak that high on the motor.

I would try a 'black light' in a dark garage to catch the flourescence of the antifreeze trail......

Thanks stealth. I have triple checked the connections of the TB bypass. No signs of leaking. Ever. I thought about pulling the alternator (I've done this once, it sucks) but if there's nothing back there I'm gonna say screw it. I never thought about the blacklight, I wish I still had mine from when I was young! Looks like I'm gonna have to wait to start her up and check while it's running. I've read plenty of stories about internal coolant seal failures, but not many on external seal failures. Are they common? Im hoping that its just a leak and not a seal failure.
