Slap yourself repeatedly and then call a mechanic like you should have in the first place!
Get a new radiator or flush it out?
Yes.
You don't put water in your radiator, you put antifreeze.
any kind of oily oil will work. open the hood and put some in the engin and the radiator to keep it well lubricated.
No. Let it cool down before you open the radiator cap and then put water in the radiator
You can put ice in your radiator. Keep in mind that the ice is just water and you should have SAE certified anti-freeze in your radiator
Circulating water will not be sufficient and the car will overheat.
I have a 93 roadmaster and I'm trying to put a radiator in, so what size line wrenches do i need to connect the oil cooler
Take it to an oil change place and have them do a cooling system flush immediately.
A cracked radiator will NOT put water in the engine and make the oil milky. A bad head gasket WILL put water in the engine and make the oil look milky. That does not neccessarily mean you have a bad engine. Have someone fix or replace the radiator and replace the head gasket. It could be a good engine for a long time yet
Yes.
The engine oil is put in through the oil cap on the engine , it's on the passenger side valve cover , on an extension pipe , that is just behind the top radiator hose
