When I cut my car off, it seems like I hear a little hissing sound comming from the lower front part of my engine bay. I checked all the fuel lines, and nothing was amiss. I do however see the top of the plastic undercowling under the car is a little wet. Looks like I may have to upgrade to a Fluidyne Radiator from AWR Racing when I get the funds. I still have some stuff to pay off. I hope that my radiator lasts long enough.
