    Why is only distilled water suitable to add to cooling the car? What happens if you use tap water?

    Anti Freeze would be more proper. I've used tap water many times. The reason for the recommendations for distilled water is that all impurities are filtered out. Less chance of internal corrosion.

    Nobody listens to that junk though. Tap Water is fine. If adding to a battery then yes distilled water is the correct choice. Particles of tap water will collect on the plates and lower the life of the battery.

    Who puts water in cars anymore? Other than in the console cooler.

    good post, but on a technicality, impurities in distilled water are distilled out.

    Distilled is only way to get pure H2o. Filtered can leave a residue from the filter medium.

    From my experience after 35+ years of working on cars, it doesn't make a noticeable difference unless you put it in the gas tank. + many batteries are sealed and you cannot add water.

    /----/ Distilled means tap water is boiled and the steam is collected, cooled and bottled. All minerals are left behind. Filtered means tap water is run through a paper or charcoal filter that collects most but not all of the sediment and minerals. As an example, sea water that is distilled will no longer contain salt and you can drink it. But sea water that is filtered will still contain most of the salt.

    Thank you. I understand I screwed up my wording. Why I said I screwed up.

    Was in the Navy 10 years. Helped repair the systems. Usually Brine pumps screwed up........clogging up..................We used 6 stage distillation process on the 1st ship...older ship.................The last ship we produced 10,000 gallons in each engine room per day.............

    After distillation the water is treated with Bromine................if you drink distilled water it will give you the shits.............lol

    I ran battery shops..........we used distilled water..........as it prevents minerals from collecting on the plates...........and lengthens the life of batteries. Lead Sulphate is the death of a battery................The only thing that really matters with whether you have a good battery is the specific gravity of the sulfuric acid in the cells which can be tested with a simple Hydrometer...................For how strong the battery is you must perform a load test and record the results.
