Most likely it's automatic Transmission Fluid, check to two metal lines going into the bottom of the radiator to confirm this.
blown head gasket
There is only 2 radiator hoses 1-1/2-2 inch. 1 upper and 1 lower. If ur draining the radiator, most new cars have a pep-cock, little valve that drains the fluid. Lower hose does the same-messier,but faster. If were 2 more smaller hose- do not touch unless repl;acing the radiator-they would be for the transmission cooler- and would contain trans. fluid that would need to be topped off, unless plugged when removed(trans. plugs come in a kit but would only real know the size when u remove it.
You would remove it from underneath. There is a cross member which holds the bottom of the radiator and you remove this, after unhooking all the lines (trans coolant and engine coolant) and draining the radiator.
Probably any normal thing like not enough Radiator Fluid or something is wrong with your radiator or a head gasket leak could cause the radiator fluid loss. Does this Help?
Most Likely you have a leak from the transmission cooling tank on your radiator to the antifreeze portion of the radiator. Jeff
What would happen is when your vechile begins to run and gets warmed up your fluid will splatter all inside the hood of the vechile and your fluid will run low and it will crack your radiator.
To keep the transmission fluid cool. Without one it would overheat.
Not quite. Anti-freeze is the undiluted liquid that you mix with water (usually 50:50). The proper term for the mixture is "Coolant". I would say that "coolant" and "radiator fluid" are synonymous.
Bring your vehicle to a garage is what I would do so you can let it thaw and refill it with antifreeze because there must be water in the radiator
