Ok, awhile back I got an overflow tank from someone on here. I finally found 10 mins of my life to swap it out(i know b.s.). kept the cap that came on the tank and filled it up, drove to work yesterday and drove home, when i got home, the car sounded a bit funny and i decided look under the hood, and noticed i had some coolant on the tank, i thought odd. so i shut the car off and heard a slight hisss from the overflow tanks cap. I already had a new cap that i had bought when i first broke the cap on my older tank. Replaced the cap this morning before going to work. got here and shut the car off and popped the hood and heard the hissssing noise again from the cap. Is this normal??? My old tank had a little hose coming from the back corner of the tank like an overflow drain tube, my new tank does not have this. Any help would be greatly appreciated.
