Hello guys. I'm pretty new to rx7 stuff. So i started my car this morning and it gave me the add coolant signal and buzzing sound. I went to check the outside and there's like a puddle of something coming from underneath the car. I added cooland and here's what it gave me.

 

I don't know exactly where the leak is coming from but the spewing is coming from between the alternator and the piping by the left side of it.

 

There's are sensors on the back of the t-stat housing as well as a small section of hose for the termination of the throttle-body coolant line that could conceivably be the source of your leak. I suspect it's going to be that coolant line. You'll have to remove the intake (if stock), cross-over pipe and alternator to access them. BTW there are TWO adjustments for the alternator belt. One is under the airpump and often missed by first-timers. Since it's a formed hose I'd get a replacement from MAZDA and reuse the STOCK spring hose clamps if they're there.

 

Hello guys. It's me again. Lol I found the culprit of the leak. It's this ruptured hose!!!! (as seen in the picture)

Located just underneath the radiator hard plastic air ducting and left side of the alternator.

 

Throttle-body coolant line termination just underneath the intercooler crossover tube. As previously mentioned, I'd go back to MAZDA for the replacement. NOT the local chain parts store. And use the factory clamps.
