RADICOOL SF Pink FAQ
Do I need to mix Castrol Radicool SF Premix with water?
No. It is premixed and ready to use. The maker says you can pour it straight into the cooling system without adding water.
What vehicles is Castrol Radicool SF Premix for?
The maker says it works in gasoline, diesel and gas engines and in all radiator types. Check which coolant type your owner's manual calls for.
Can I mix it with a different-colored coolant?
Don't mix coolants of different types or colors, because their corrosion inhibitors may not be compatible. To switch types, drain and flush the system first. The maker lists this coolant as pink/violet to light red, but go by coolant type, not color alone.
Can I open the radiator cap when the engine is hot?
No. Wait until the engine cools before opening the radiator or reservoir cap, because hot pressurized coolant can spray out and scald you.
Is coolant dangerous?
Yes, it is harmful if swallowed. The maker adds a bittering agent to deter accidental swallowing. Keep it away from children and pets.
