It use to be said a high concentrate of gylcol would eat away at gaskets. Not too sure if this is still the case
Nothing. It will not hurt anything.
Once your vehicle is warmed up, if you have antifreeze coming out of the overflow you have too much in your radiator.
If it's a question of too much fluid it can overflow, if it's a question about the fluid being too concentrated - don't worry about it.
Don't forget 50/50 solution too What kind of vehicle? What size engine? You don't add antifreeze to the engine, anyway. There should be an overflow jug on post '85 vehicles and on pre '85 vehicles you add the antifreeze to the radiator only. Please check your owner's manual or ask your car dealer for further information.
If your vehicle seems to be having problems try to add the anti-freeze as soon as possible. If you don't use your vehicle much it can wait for when you have time.
Yes, it does hurt.
You can run up to 75 percent antifreeze without any trouble. -------------------------------------------------------------------------------------------------- Actually , Ford states not to exceed ( 60 % antifreeze )
It depends on how much over. A little won't hurt. Too much it will foam and not lubricate. Meaning your engine will wear out much faster than it should.
It hurts alot but try not to think about it it won't hurt if you don't get scared too much
No, if anything it would get cooler from having too much. -You have a different problem, possibly a coolant leak.
