| If coolant is actually getting burned in the engine, the car will put out a lot of white smoke, Which should be very easy to see if you watch it take off. If the head gasket is leaking, It's a near certainty that there will be obvious oil in the coolant reservoir, which can be seen by the formation of a pudding-looking white mush around the rim of it. Otherwise, the same stuff could be seen on the oil dipstick.
In any case, I doubt that's the case. More likely, it leaks at the bottom passenger-side of the radiator, and only when running, so it's hard to see on the garage floor. Use pliers to bend in the metal near where the lower radiator hose comes in.
Also, replace any coolant hoses that have a swollen look, and replace the corresponding clamps.
