I have been using green anti-freeze mix 50:50 for more years that I can remember. As long as the hoses and water branch joints are in good order there should be no problem. Modern vehicles tend to use OAT coolant (Organic Acid Technology) which is also possible, but it is not compatible with other, ethylene glycol based coolants. A complete flush of the system is necessary before changing over.
