Either a blown head gasket or a blown radiator for the transmission cooler. Disconnect transmission lines loop them together with some hose, flush radiator see if it presists.

A guy from mazda said the cooler is in back not in the front. Didn't sound right to me. The oil is low when i changed it 2 months ago and it wasn't..it did seem pinkish in color to me..kinda like brake fluid. Nikki check engine light it's on..the blue temp light comes on at start up but goes off after a little bit..never the red that indicates over heating. I'm praying its not the head gaskets..what do y'all think

Its leaking right beneath the radiator onto the skid plate connected to the front clip....the over flow is full of coolant andr what ever fluid is leaking into the radiator..i can usability figure this stuff it but I'm notsure on third one..i think I'm going to flush the radiator and change the oil again and see if someone done this or what. Any help will be appreciated


No check engine light it's on so no codes to pull either
