after not driving my truck for an entire weekend I decide to go out and play with it a little. I spin the tires you know that kind of stuff and after going not less than 5 miles I come home and park it. I get out and as I am walking away hear a noise. Not a clunking or banging noise or anything. but when i look back its got steam coming off of it like ALOT of steam its been raining here for two nights and its really cold. What the hell did I do.
