Hey everyone my names Matthew, most call me Matt. Im 23 and live in Milwaukee Wisconsin. I own a 2008 tC with 120K, I've always taken care of my car, have been in one fender bender and went through one clutch so far. My car recently has been making a horrible rattling when running sounding like its coming from behind the motor underneath, I was told it was the cat. Well Its gotten really bad and today as im parking i hear this horrendous clicking noise so i immediately turn the car off and get out to look at things. Everything seemed fine until I saw that my coolant was really really low when it was just full. So i check under the car and see coolant just streaming down and don't know where its coming from. I dont know what to do or how the cat would even effect the coolant. I hope you guys can give me any kind of help if possible. Thank you.
