But if there are better ways of doing this, I'm all ears.

I have easy access to antifreeze so here is my question. If I put the drives is barrels filled with antifreeze and run the engines untill operating temp will this be good enough? I figure I can check the protection level of the coolant in the barrel since it will be mixed with the water that is currently in the engine.

Thanks, Jerry.
