Antifreeze coolant is one of the most vital fluids in your car's operation, since it protects the engine from corrosion, from boiling or freezing temperatures, and helps transfer heat from the engine to the radiator.  While water could potentially serve the purpose of heat transferring, most coolants only contain 2-4 percent water, which is subject to freezing and boiling.  The main ingredient of coolant is glycol; usually, ethylene glycol, and the rest are additives which protect your car's inner workings against corrosion, rust, and pitting caused by air bubbles imploding in the cooling system.

Few things are more dispiriting than turning the ignition key and hearing nothing. Just when you need your car to start, it plays dead.  Modern car batteries are very reliable, but leaving the lights on for a few hours will soon discharge them. Even a boot light or an interior light left on overnight can flatten a battery. And a car left standing for a month or so may discharge its battery just from the current drawn by the alarm.
