Unless the water in your area is especially "hard" I wouldn't be too concerned about using it. You are correct about running straight water. Unless you are testing for leaks you should always have anti-freeze. It should be a name brand permanant type mixed 50/50. It is very important in the Delorean with aluminum and steel parts. Name brand anti-freeze will have lubricants for the water pump, corrosion inhibiters to prevent the dissimilar metals from interacting with each other and sealers to help seal minor leaks. The two main things to check regularly are the boiling/freezing point of the mixture and the PH. If the coolant gets acidic it will start attacking the metal components from the inside. The best insurance is to change the anti-freeze every 2 years or so if you don't have access to a way to test it. Most places have test strips like you use on a swimming pool but made special for checking anti-freeze. Always dispose of used anti-freeze properly and keep animals away from it, it smells sweet to them and if they ingest enough it will kill your furry friends! Never run more than 50/50 or you lower the boiling point even though you can lower the freezing point. (You only do that in the most severe climates and then only for the winter.)
