I finally finished my water pump and everything looks good. I drove the car around alittle bit and opened up the hood and there was hissing coming from the radiator cap...I put my ear to it to make sure. Does this mean I just need a new cap or is it normal seeing as the car was off?

On a side note Merry Christmas!
