okay guys, so i let my cobra sit for about 4 days and i got in it today and while i was driving down the road i seen coolant coming out of my hood vent. so i pulled over quick turned it off and opened the hood. when i opened the hood i seen coolant everywhere around the radiator and reservoir so i thought it was leaking from the cap so i went to the part store and got some coolant and a cap. put the coolant in and the new cap turned it over let it set to normal temp so i decided to get on the road again. as i was driving the heat hand started rising again so i pulled over real quick and turned it off. so what could it be? i've checked all the hosing none of them were leaking and the reservoir is good and the cap. so why could it be? oh and as i was goin down the road my heat wasn't hot at all. thanks in advance for advice.
