drain radiator and refill according to percentage in manufacturers handbook.
just drain half of it and top up with water,to much antifrezze will quickly corride internal parts of the engine,
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.
No, if anything it would get cooler from having too much. -You have a different problem, possibly a coolant leak.
You can run up to 75 percent antifreeze without any trouble. -------------------------------------------------------------------------------------------------- Actually , Ford states not to exceed ( 60 % antifreeze )
it varies by car to car
A car's cooling system is designed to contain a certain amount of fluid. With too much in the system, the fluid will expand after reaching high temperatures and you might see a puddle of antifreeze. Don't worry, the puddle is due to the overfill Make sure to check your overflow reservoir after you shut off your car. Make sure that there is still some fluid left in it.
So that the water used as coolant in most car radiators does not freeze overnight. If it does then, because ice expands as it freezes and melts, it can crack the engine block. The antifreeze lowers the freezing point of the coolant and reduces the risk. The more antifreeze, the less risk of freezing. But too much and it will boil when the car is running. Additives in antifreeze also reduces corrosion and raises the boiling point.
Antifreeze/Coolant is a fluid that prevents the car from overheating or becoming so cold that it won't start. Without it, in the summer, your car would run too hot, and in the winter, your car wouldn't run at all.
Once your vehicle is warmed up, if you have antifreeze coming out of the overflow you have too much in your radiator.
Putting 100% "straight" antifreeze in your car's radiator will expose the cooling system to freezing at a much higher temperature than would the appropriate and recommended mix of roughly 50/50 antifreeze and water. Antifreeze works best WITH water.
Low antifreeze, No antifreeze, Stuck thermostat, plugged up radiator, Old radiator with no more fins to disipate heat, or all the fins are plugged full of debris, Antifreeze mixture bad(too much or too much water) one or the other is no good for 200 degrees but together they work great. also if your car? has to have all the air bled out of the system to function correctly.
you can use as much as you like as it makes the car run cooler
Nothing. It will not hurt anything.
