X 2. If you're not leaking coolant, you're bruning it. Only 2 ways to lose coolant.

have the cooling system pressure tested by someone who knows their way around a car before you go doing anything serious.

If you have an 00 or an 01 and you have "unexplained coolant loss", the odds are quite high that you have a cracked cylinder head.
There is a known casting defect between cylinders 3-4 on that head. And the #1 symptom of a cracked 0331 head is unexplained coolant loss.
So if you have performed a comprehensive search for a leak and have found none, you likely have a cracked head and you need to educate yourself about it and do it fast. Coolant mixing with oil will toast your engine bearings and wait long enough and you'll need a rebuild or a different engine.
Instead of reinventing the wheel, read this thread.

Note to self: Never ever buy anything from Firestorm. I mean ever...
As for the OP, welcome to the cracked 0331 head club...
Takes about a day to take the old head off, three days to get a new head from Clearwater and another day to button it all up. Total cost including replacing all gaskets and the cooling components (except radiator) ~ $700.
