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.
You want a 50/50 mixture. You can purchase it all ready mixed.
50/50.
