Have you already started your engine? I don't remember.

I'm installing a newly rebuilt inline six in Little Red next weekend but I'm going to fill it with water. If there are any leaks or other problems, I won't have wasted $12/gal coolant.

Once it's all proved to be hunky dory, I'll drain it and refill it with proper coolant.
