You need a 50/50 mixture of water and antifreeze.
Usually 50 / 50 mix ( Ford states not to exceed 60 % antifreeze and preferably distilled water )
Any Ethylene Glycol based coolant mixed in a 1:1 ratio with water. Prediluted means it is already in the correct ratio.
The proper ratio depends on the temperatures your vehicle will be operated/stored in. Typically, a 50/50 ratio will be just fine. If you will park/store your vehicle in extremely cold (sub-zero) temperatures, you can increase to 60% coolant to 40% water.
50/50
Minimum 50/50. Maximum 70/30 (coolant/water).
50% water to 50% coolant is the standard unless you live in a very cold climate where it goes down to -25 degrees F or lower, then you may want to mix 25% water to 75% coolant but never straight coolant.
Ok, 50/50 is pretty much the norm. Coolant is not what keeps your engine cool, the water is. The coolant is what keeps the water from freezing in cold weather as well as from causing corosion to your engine.
50/50 50% Dex Coolant and 50% Distilled Water. This is assuming you did not buy a premixed gallon of coolant. This will protect you to -40 F.
No the 600 ml concetrant coolant will not harm your car. The ratio, however will be affected.
Coolant container will say if it is pre-mixed or full strength. If full strenght, mix it 50/50 with water. Pre-mixed coolant can be added "as-is"
It is always 1 to 1 ratio. If you get the premix then you dont have to mess with mixing it yourself. Good luck.
