Its more than likely condensation from your air condition system and nothing to worry about.
you might have a blown head gasket and the coolant is leaking into the cylender and the engine is burning it.
Your engine may have a leaking hose connection or a leaking gasket at the water outlet. It could also be a leaking hose.

Yes, coolant can leak from the engine. If it's hot outside and you're running the Air Conditioner (AC) and you back up and see a liquid on the ground, it's probably condensation from the AC unit. Or, it could be collant leaking from the engine. How old is the car? Do you consider radiator hoses to be part of the engine? Radiator hoses should be replaced every 3-5 years, especially if there are bulges, or if they're leaking.
Could be leaking transmission fluid.
Probably not. White smoke indicates engine coolant getting into the engine cylinders and burning off. This could be a from a leaking head gasket or a crack in the block.
could be freeze plug, or intake leaking
it could ruin your engine, to were it is unfix-able :(
The clear liquid could be indicative of a basilar skull fracture.
If it's leaking transmission fluid, could be a bad pump seal. If it's leaking engine oil, could be a bad oil filter, leaking valve cover gasket, leaking intake manifold gasket, leaking oil pressure sender, leaking distributor gasket.
Bumps that release a clear liquid when squeezed could be many different things. Examples they could be are acne, cysts, poison ivy or boils.
could be bad piston rings,are your spark plugs oily,is your carb.tuned right,your intake manifold could be leaking
