You can use diluted coolant by itself, or a 50/50 mixture of concentrated coolant and distilled water..

Can I use water instead of coolant in an emergency?

Yes, you could use water as a coolant in an emergency. However, doing so is not recommended since water won’t work well beyond its freezing and boiling points. This could also cause expensive engine damage. So, use it only in unavoidable situations.
