Help! Anti-freeze Problems

I have heard this gurgling sound like everyone else and now I have ANTI-FREEZE EVERYWHERE! Under the floor mats, in the vents, on the windshield. Someone help. I was told it was the heater core but need help on how to replace that. PLEASE HELP

I would highly recommend you get your self a service manual and read how to replace the heater core, read it twice, before you start to take things apart!!!!!! From a certified auto tech!!!!!!
