Low coolant in coolant reservoir, just noticed the other day when I changed the oil. Low as in almost empty.

Only four places it can go, right?

1) Internal engine leak
2) External (to engine) hose/clamp/water pump/gasket leak
3) Radiator leak
4) Heater core leak

Have not seen any coolant on garage floor. Just out of warranty. Suggestions?
