This product is already pre-mixed for the correct concentration. If you are going to use this product I would suggest draining and flushing your system, then use only engine ice to fill. I use this in my bike and have notice it does run a little cooler. In an emergency situation you can top off the system with water, however that will dilute the chemicals in the formula so you should flush the system when you get a change. I try and stick with the same brand and type of coolant after any flush....Just like you wouldn't mix different types/viscosities of oil....
