My coolant level has droped to near empty over the last 5 days.

-Engine temperature stable and holding.

-No engine smoke from the oil compartment.

-Found small puddle of what seems like coolant under the radiator on the ground.

-Engine Oil level at full, clean, no noticable oil burn.

Is it posible for the engine to burn all the coolant in a total of 5 days (1 hour total engine running time within 5 days) and have absolutly no smoke from the engine compartment.



Recently purchased car, dont know much about it....

 

is any smoke comming out of your exhuast?

 

Best case scenario, your rad has a leak, or water pump weephole is leaking (sometimes hard to find that one). If both parts are original, or look like they are, check those first...

 

run a pressure test and see where it's leaking from...

 

If the engine was burning it, it would come out the exhaust in the form of a sweet smelling cloud of white smoke...specially on startup. Get a new thermostat and the correct mazda radiator cap, then check all hoses and go from there.
