    Filling the coolant with water is not a big problem. If it gets overfilled, all you need to do is simply suck out some amount of water. If you find extra amount of water inside your engine instead of the anti freeze, and if it doesn't surpass the threshold limit, there's nothing to worry about. All that you need to make sure is top up next time with neat anti-freeze to correct the ratio of the content. 

       For those who live in the colder regions must keep in mind that water freezes at 0 degree Celsius. This would freeze the motor and stop working. So one needs to make sure that the 7:3 ratio must be maintained to keep up with the proper cooling.

    So what just add an equal part of antifreeze you will be just fine.  And how did you make that dum mistake?

    No problem will come from you adding water to the coolant overflow tank. The excess might blow out onto the street next time the engine gets up to operating temperature, and that still is no problem. Have a good day.

    No worries. Next time state the volume you put in.  A cup of water is different than a Gallon of water.  You get different advice.  Also the make of the car.  Many cars on the road, many years. Many different size radiators.

    Top it up with concentrated coolant to fix the problem. Use a syphon to make space if necessary.

    As long as it was water and not windshield fluid, you're fine.  Coolant is a mixture of water and glycol.  If you added a LOT of water, you'll want to check the % to make sure you  have adequate freeze protection depending on temperatures where you live.  If it was a few cups, you're fine.

    Providing you're using a proper coolant mix incorporating water and antifreeze all you've done is diluted it a little. Assuming you didn't put a large amount in it will be no problem, though you might find your coolant freezing at a slightly higher temperature than before if that matters wherever you are. 

    If you're overfilled the overflow bottle just drain it down to where it should be.  All will be well.

    It's not going to hurt it a bit next time put antifreeze and to top it off.

  • Usually, your coolant mixture is 50/50 antifreeze and water, so adding a little water to the coolant isn't going to be a major issue.  Just make sure that you haven't filled it up too full.  If you have, then drain some out until you're just below the "Cold Max" line on your tank.

    EDIT:

    Now, there are options that some people have taken, with alternative coolants, where there is no water in the system.  These coolants have a much higher boiling temperature, which means that they don't expand as much as water does when the engine heats up.  If water is in the system with this other coolant, it'll expand too much and cause too much pressure to build in the system, which can cause ruptures.  However, these alternative setups are aftermarket and usually not done (the cost just isn't really worth it), so the chances of you having this in your vehicle are almost non-existent.  But I wanted to cover my bases, like WebMD does.  I didn't want to tell you that water in your system is 100% harmless, when there are cases when it can be a problem. even if those cases are rare.  Kind of like how WebMD will tell you that your headache could be the result of an illness, a cold or flu that's making its way around, blood pressure issues, or a brain tumor (oh God! Not cancer!!).  Sure, the tumor is much less likely, but they still throw it up there, by God, and scare the bejeezus out of you.

    You have put water in the coolant, that's fine. Water or, a mixture of antifreeze with the water is where you're supposed to put it. Its a coolant for the engine. The windscreen bottle is where you put screen wash for the windscreen.
