Provided there is no water in the car and it is not subjected to freezing temperatures there would be no problem. If you are going to let it sit unstarted for any length of time, all fluids should be drained, the tires would be treated, it should be resting on blocks or jackstands securely, and the battery should be removed. It would be best if you could store it in an enclosed storage like a garage or at a storage facility, with desicant packets in boxes surronding it, but if this is not an option, cover it with a car cover or tarp.
It depends on how bad the leak is .If its a really bad leak to the point where the car is starting to overheat then no
bad water pump
Bad or clogged heater core. Backflush it.
You could have a bad water pump gasket.
Generally, if your car overheats with the proper level of antifreeze, either your water pump has gone bad (not circulating fluid), the thermostat is stuck, or your radiator is clogged up inside. -NAPAman
bad head gasket or cracked head.
You have either a cracked heater core or bad heater hoses that are allowing antifreeze to enter into the vehicle............
No, it does not.
The type of car antifreeze that is safest to the environment is propylene glycol antifreeze. While it is still not totally safe, it is less toxic than other antifreeze.
It may have overheated and boiled over. It may be a small leak in a hose or the water pump. You'll have to find out where it's comming from before you can figure out what is going on. If the car is sitting for a while, check the coolant reservoir for leaks.
My dad puts antifreeze on his car.
no but antifreeze in oil will eat the bearings
