If I do not have enough distilled water for coolant mix, can I temporarily use tap water?

Asked by May 23, 2015 at 12:33 PM about the 2002 Toyota Tundra 4 Dr Limited V8 Extended Cab SB

Question type: Maintenance & Repair

I am adding coolant to my new radiator, realize I have only about 1/3 gallon of distilled
water for the 50/50 coolant/water mixture, and there's no way to get to the store. If I
complete the mixture with tap water, should I sometime soon empty the radiator and re-do
the 50/50 mixture with distilled water? Thanks for answers.

You'll be fine with tap water as long as you're not using well water. City supplied tap water is purified for human consumption so it'll be fine for your car. I've always used city supplied tap water without any problems. You can leave it in there as well. HTH. -Jim

No, distilled water has no hard water properties, which both city and well water have. I would say just drive it without being filled up if its not a long distance, just wat h the temp gauge. But this depends on the distance.
