Hey guys I'm new here and I gotta say this site is pretty nice. I need some help though. My 07 gt is bone stock and ocasionally when I start the car I get a big cloud of smoke out of the exhaust. I haven't noticed coolant loss or the oil level dropping or rising. When the car is warm, the radiator hoses are pretty hard. Is this normal or do I have some hidden problem because Im lost? I hope the car is ok.
