Default Coolant loss ?

I am losing coolant and I am getting some smoke out the back. Where is the best place to look for a coolant leak into the engine?

What kinda smoke-sure it's not steam. I'd be checking my engine oil first to make sure coolant wasn't getting in the oil-exhaust smoke-or steam and coolant loss could indicate a blown head gasket. How are your engine temps? Maybe time for a compression or leak down test.

...and take this problem seriously. The water boils off, but the Glycol coats wear surfaces and inhibits lubrication.

Check the hoses. you don't want the coolant hitting your OPTI.

Temps a little high, no coolant in oil. No, I know it is smoke from coolant. Just want to know the likely spots for coolant leakage into heads on a LT1. Intake manifold or head gasket?
