Any help would be gratefully appreciated.

Hissing at the coolant cap is normal as you are dealing with a pressurized system. Whether the car is cold, warm, or hot has everything to do with coolant coming out of the over flow. The overflow is located in the space provided for your oil fill cap and coolant fill cap. Between the two at the bottom you will notice a small hole. If the car lets out some coolant when you open the cap because its warm or hot, then it will flow out this tube and run onto the floor next to the right rear tire. As far as coolant, Porsche uses G12 coolant and or the "Pink Coolant" for the 9x7 cars and more often than not Zerex or "Green Coolant" is used for 9x6 cars. If its been flushed sometime in the past it may have had the G12 put in it. Little bit more evironmentally friendly.
