Why is my Mazda losing so much coolant?

Hi Gerry,

There are so many things that could cause this we'd recommend you bring the car to a qualified mechanic - and soon before damage is done to the engine. Coolant puddles under the car after it has been idle for a while point to a leak in the cooling system (pipework, radiator, etc.) and white smoke coming out of the exhaust suggests something more serious.

Either way, get it looked at without delay and let us know how you get on.
