is that thing on the toop of the radiator the coolant level sensor?? i know its a stupid question but when my radiator blew it was cause that sun of a bitch stripped right out and my car looked like a freaking fog machine on wheels for about 20 feet. i just bought a new radiator and thermastat but i will prollly need to get an new one of those too, so first is that what it is and second where would i get one?? ohh and third where is the thermastat i thought if im going to replace the rad i mine as well do that, and i know you say make sure get the hoses well snap im out of money, damb speeding ticket, and so i either keep her sitting there for about another month or use the old one with some hot glue to seal them on, that is unless anyone has an upper and lower one they will sell me for a little cheaper then 45 bucks!!! i know that was a lot but i need the help thanx
