What causes a car to lose antifreeze?
You either have a leak or your engine is using antifreeze. If your engine is using antifreeze, it will usually be caused by a leaking head gasket, cracked head or block. If your engine is using it rather than a leak, pay attention when the car is running. If there is white smoke coming out of the exhaust it is a problem within the engine. If there is a leak, lift the hood and look for steam arising from anywhere, also look on the ground for any antifreeze dripping onto the ground. If all that checks ok get in your car and turn your defroster on. If your window gets covered in moisture and the moisture smells sweet and looks like a weird color, it is your heater core in the dash leaking, also the heater core can make the floor board wet wherever it is located.
