What happens if you overfill coolant?

I know what happens if you overfill oil, but what about coolant? Will it start blowing out of your engine, or will it just flow into (and then out to the ground) of your puke tank?

Fill it completely full. Fill the overflow bottle about a 1/3 full.

Cold, but no snow yet, so I can't complain

Alex,

One thing to be careful of...pets.
If you have a dog or cat, they just love the taste of this stuff.
If you spill it on the ground, and they lap it up, they're in trouble.
It only takes a very small amount to kill them.

When I did my first start I filled it to the top and then filled about 1/3 of the overfill as has been suggested. I ran over as the fluid heated and expanded. It may take a time or two until you get it right so the overflow doesn't overflow.

As John noted ethylene glycol (anti-freeze) is very sweet smelling to pets. They will run to it and lap it up. It only takes one or two laps to kill by shutting down their kidney's.

Very sound advice. I came real close to losing a dog to coolant...costly vet bills...he should have died but thankfully they saved him.

To answer your original question, it won't hurt the engine or anything else (other than the aforementioned pets) if you happen to overfill. It'll just puke out your overflow tank as it expands from heating.

Just because it pukes however, it doesn't necessarily mean it's overfull. The same symptom can also indicate it's not full enough.
If you have air bubbles, that can also make it puke, as the water flashes into steam and really expands (know how steam engines work?).
