depends on the type of vehicle
no water! should be a 50/50 mix of antifreeze, 50% water 50% any brand antifreeze
Do not operate the washer. Remove the washer fluid reservoir and flush it with soap and water until all traces of antifreeze is gone.
I'm not sure about a Honda Accord, but all cars are pretty much the same. You can remove the radiator cap and add antifreeze, or you can look for the antifreeze "overflow reservoir". A piece of tubing from near the radiator cap should run to a plastic jug about the size of a gallon or two. It usually sits off to one side or the other under the hood. The side of the overflow reservoir may have a fill mark on it. The top should have a lid that is easily removed. That's probably the recommended place to add antifreeze.
In the coolant reservoir when the engine is cool.
The drain plug should be located on the lower right corner of the radiator, it is about the size of a nickel with raised ribs that form a cross. You should attach a rubber hose to the radiator drain before opening the drain plug, this keeps antifreeze from splashing out. Antifreeze is a corrosive, that will burn your skin, and destroy your body paint.
Your 50 / 50 mixture of antifreeze and preferably distilled water should be right near the top of the radiator ( as long as you can put the cap on without the antifreeze mixture overflowing ) The plastic coolant reservoir in the passenger side of the engine compartment has a cold mark on it , just maintain your coolant level up to the cold mark when the engine is cold . ( Ford recommends to not drop below 40 % antifreeze and not exceed 60 % antifreeze in your engine coolant mixture )
Not sure what you mean by coolant port... Antifreeze can be added to the cap on the passenger side of the radiator if it is low and the reservoir on the driver's side should be filled to the line when cool
You don't put water in your radiator, you put antifreeze.
A hot radiator releases excess coolant through the spring-loaded cap in to the reservoir, and when cooled the partial vacuum created by cooled radiator pulls it back in. A reservoir should be only about 1/4 full cold on a system that uses a radiator cap, some cars have a pressurized cap on reservoir and no cap on radiator
My guess is that it should pur itself but double check with a parts store.
there is an antifreeze overflow tank, look on the radiator next to the radiator cap and there should be a smallish hose, follow it and you will find the tank.
then you should have your radiator flushed because you have rust in it. FYI: antifreeze can strip the paint off of your it you spill it. Also, you may need to replace your radiator if the antifreeze is leaking, it may be through a rusted/corroded portion of the radiator.
