So I just bought a 95 Regal, got 5 miles from home and the wheel studs broke on right side tire. Too late to fix tonight, so the boat is beside the interstate until morning. Biggest problem is I/O motor was run today and its supposed to get down to 30 degrees tonite. Do I need to go drain the block and manifolds or will it be OK. A quick response is appreciated as it is 7:00 pm now. Thanks!
