The ion-exchange process works similar to a water softener but takes it even further. You must log in or register to reply here. In this post, we explored in great detail the topic of distilled water vs reverse osmosis water. Dunno. Distilled water is often more pure, especially if it's been filtered first, and it should not contain any bacteria or other pathogens which could, in theory, be left in DI water. Notice the bottle of concentrated coolant says to mix with deionized water. And what happens if you put deionized water in a Saturn Ion? Deionized water has had all ions removed and is neither positively or negatively charged. Everyone should use deionized (or at least softened) water in their radiators for the reason listed by Leo. Distilled water is purified water that has been boiled into steam and collected. This type of water has had all ions removed and no longer has any charge, positive or negative. Since it’s basically a blank slate, deionized water will pick up anything it contacts. However, it’s still got ions present that can be removed in the deionization process. I mean if you used PURE 100% water, maybe. Chuck Since it lacks ions, it can actually absorb the ions from your body, robbing you of essential nutrients. Ever since that day he has worked towards making the world a better place. That's more than enough for your pump to move … You can also use deionized in batteries. It may not display this or other websites correctly. These days, with all of the hoopla' about ruining something in the engine(W/P, H/G, IMG), I've become reluctant about using anything other than the dealership coolant w/ distilled water...and ATF for that matter! If you're not using well water or water with a high mineral content then distilled is over kill. Shelf brand coatings vs higher end brands. Distilled water is devoid of all contaminants and minerals. If it is transported through pipes, it can pick up metals from those pipes. He first learned about water filtration and the impact it has on the world in college. However, other contaminants like bacteria, chemicals, and viruses may still be present. I have been using tap water for the past 20 years for what it's worth. I don't use it simply because I would have to make a special trip to buy it and the additional required shelf space in the garage. Substituting Distilled and Deionized Water . Am about to change the radiator fluid and was wondering if either distilled or demineralised water is better for the radiator/engine. For a better experience, please enable JavaScript in your browser before proceeding. ===========. Corrosion protection is a little ammonia, hydrazine, and/or carbohydrazide, and they last 30 plus years doing so. Deionized water is very nearly as pure as distilled (or more pure in some cases from what I gather) and for radiators it doesn't matter which. But, they differ in two different ways. Tubes are steel, 5mm wall thickness, and run at 2,600psi and a few hundred degrees. It also won’t replenish any of your essential minerals either, so keep that in mind if you decide to start drinking it. Well, if you did use JUST deionized water you would have issues. Either a translation thing or an ignorance thing. Since it’s basically a blank slate, deionized water will pick up anything it contacts. Maybe they meant distilled. You are using an out of date browser. (Seems a little over dramatic to me. Deionized water, it's what we use in development engines. 1. The newest car in my stable is 15 years old. For this reason, deionized water is often passed through a reverse osmosis membrane prior to being filtered through the charged resin. otherwise tap is good. Both types of water are great for lab work, but since deionized water lacks a charge it is often the choice for situations that require high levels of water purity. At the power stations, all of the boiler water is de-ionised, through an anion, cation, and mixed process. The PH acidic and as a result attempts to correct this by pulling metal from the radiator (it will corrode the water blocks to get So better choice is distilled, but your will be fine with deionized as well. You don't generally want to substitute one type of water for the other, but if you have deionized water made from distilled water that has been sitting out exposed to air, it becomes ordinary distilled water. This is why all race orgs say to use "distilled" water only vice deionized OR distilled water. I replaced my water pump on my old 96 Merc GM when it had 190,000 miles( for preventive maintainance) and the inside of the pump and engine were spotless. Deionized water and distilled water are both in the running, but you may not even know what they are. Purified water is required for a wide variety of uses including industrial, medical and home use. My choice for my 928's radiator is Texaco DexCool and distilled water. ========================= While the significance of the PH isn't anything to be concerned with right away, over time this can have an effect on a radiator. But the problem is that when water is distilled, or “stripped,” of its minerals and impurities, the resulting solution is composed of chemically imbalanced “ions.” Distillation, however, is energy-intensive and involves capturing the condensation of boiling water. One goes for pretty colored coolants, the other wants only cooling performance and doesn't worry about looks. Today, of course, we do the opposite to prevent scaling etc. its ions back) to correct the imbalance. He writes to inform you about water filtration, the consequences of plastics, bottled water, and how we can do things better. First Generation Camaro Info and Tech - 1967-1969. This filter will collect any chemicals that may have boiled off with the water. Updated Dec 29, 2020 | Same topic: Handy Maintenance Tips We could say that the best use for the radiator should be a mixture of both car coolant and distilled water. It has been recommended from the manufacturer of the coils to use distilled water. Note: Don't use deionized water. This means that distilled water is superior for drinking, but it’s still not the best choice of water to consume. Will deionized water harm copper tubing in a heat exchanger 2004. Deionization involves the passage through ion exchange material which removes ions such as calcium and fluoride. This means it’s not the best choice for drinking, especially if it’s traveling through plumbing after being deionized. At the very least, all you need is distilled water. Not only does it taste bad since it’s missing all minerals, but it’s also not good for your health. Using deionized water a few times really isn't a big deal, but being left in for an extended period of time can have harmful effects. I've kept my last 3 cars 16, 17 & 18 years and only 1 of those vehicles needed a radiator around 15 years and it was only due to exterior rot, way down low where I must not have blasted out the road salt well enough during my winter washings. This ensures that there is nothing but ions remaining to be removed by the resin. Use only distilled water. To be classified as purified water, it must contain 10 parts per million (ppm) of total dissolved solids or less. It contains just one part per million of dissolved solids. Since both treatment methods produce high purity water, choosing between deionized water vs. distilled water often depends on how you're using it. Alone, neither one is better because of the following reasons. Not to say that the other radiators would have lasted much longer, I don't know. Is much purer than distilled water. Deionized water underwent a deionization process. Now I am hearing that you should only use distilled or de-ionized water. By itself, distilled water, is much better at heat transfer compared to antifreeze/coolants. The lack of ions means it’s not a healthy choice for drinking since it can rob your body of ions you need. Distilled water will also carry over inorganic material in small amounts so the purity regarding TDS will be higher than DI. Where they differ is that deionized water is water that has had all the ions removed from it. distilled is very cheap, and good, if you live in an area with hard water. I also keep all my vehicles for at least 10 years. Of course, it will need to be treated by more than just deionization to be useful for most of these situations. Both produce types of pure water, but depending on the end use, the type of purity matters. This means that particles, bacteria, and chemicals will remain after the process. Both types of pure water are deionized. Years ago many mechanics always said NEVER to use distilled water as it "was hungry" for metal and that you should use only tap water or else you would eat right through your radiator. Kestas pointed out that there's plenty of stuff in the coolant to make it a non-issue. Why would the manufacturers all put mix with deionized water on thier bottles if this were the case - what do you guys think) He loves to spend time with his beloved wife, 3 kids, and dog when he’s not writing. In my experience, many radiators fail at the 12-15 year mark. David Slone runs the TapIt Water blog. Our Review Process & Affiliate Disclaimer. we use DI water on my job to clean wafers after etching. It will entrain ions out of concrete and anything else. Coolant Recommendations-08 Nissan Altima & 07 Dodge Dakota. It has been completely stripped of all dissolved solids, so naturally, there is no nutritional value remaining. When ultra-pure water with no charge is necessary, deionized water is the way to go. de ionized is if you own a Bentley. I have never had any radiator, water pump, head or intake manifold gasket issues with engine known for their reliability. So, distilled water is indeed better than tap water, but it will still, over time cause scale build up. Some of the people in the other movement are promoting pure distilled water as the best choice for liquid cooling as it requires almost no maintenance. It will jsut take a lot longer to do it. But once you mix even the tiniest amount of coolant/antifreeze with additives, it does not really matter how the water was purified. The sales rep says he knows of places that go as long as several years between coolant changes and sump cleaning, and the deionized water and a good oil skimmer is how they do it. You can buy demineralised water at Woolworths , RRP $3.50 for 5 litres. Distilled water and deionized water are both fit to drink, but deionized water is more pure. This process removes everything from the water leaving purified water with just one part per million of dissolved solids. The minerals in regular water prevent toxic substances from accumulating, but since deionized water lacks these minerals, it can easily pick up plenty of toxins from any source. I went to buy distilled water to flush my new radiators before using them but they only had Deionized water, can I use this to flush my radiators or is it very different? Continue reading below ↓ I brought this up years ago. That stuff is a myth with bunk mixed in. Deionizing removes all ions from water, but it does not filter the water. We have been testing new coolants in the shop from different sources. I read this from the internet - do you guys think this is nonsense: At our manufacturing facility we have heat exchangers that cool our induction annealing coils. The book further explains that at elevated temperatures of around 200C (390F) and above, both distilled and deionized water cause severe corrosion of most aluminum alloys. In the water cooling world, there are two tides. Distilled vs Purified Water: What’s the Difference? I had a radiator repaired at a local shop last fall. EDIT: Just went to the local pharmacy and got a 5l bottle of purified water for €5. Both types of pure water are deionized. This spring I disassembled an engine from a 1965 MGB that has been in the family for the last 30 years. All rights reserved. Plus, it doesn’t taste good. Just my experience. Given the differences in local water standards and mineral levels, it seems like a reasonable precaution. However, to maintain the integrity of a cooling system and to help assure long life, deionized or distilled water is preferred over tap water. Years ago many mechanics always said NEVER to use distilled water as it "was hungry" for metal and that you should use only tap water or else you would eat right through your radiator. Deionized water won’t cause corrosion like regular water might. They might sound similar, but distilled water and deionized water are very different substances. It has always been filled with a 50/50 mixture of Prestone and tap water. It's fine to use this type of leftover deionized water in place of distilled water. I recommend the use of only distilled water in cooling systems . Ions are still present in distilled water, so it won’t rob your body of any nutrients when you drink it. For 25-30 years all I have ever used was water from the garden hose and I never had trouble unless it was in an engine that was known for having trouble like Chrysler 2.2's, some Ford Vulcans, GM 2.8, 3.1 & 3.4 V6's. Distilled water is the most common kind of purified water and may often be confused with deionized water, but the two are certainly different. However, water, by itself, causes the metal parts in the cooling system to corrode. It's been recommended that we use deionized water to mix the coolant. When it comes to clean water, several types vying for the title of purest. Once this final filter is passed through, the water will be collected and is now completely distilled. Today, of course, we do the opposite to prevent scaling etc. Neutral PH and no mater how many times it is steamed, it is still distilled water. Both of these types of water meet the qualifications of purified water and fall way below the 10 ppm limit. If it is transported through pipes, it can pick up metals from those pipes. Also, we use aluminum radiators, not brass, and aluminum is more resistant to corrosion from glycol/water than brass. Otherwise all I ever used was regular green antifreeze/coolant and garden hose water. Based on my experience, it would be a needless complication, although rather … Is there any reason they don't list distilled water? The difference between distilled and deionized water is in the way that they are produced and the quality of the output water. I agree. Lessons Learned... or, how I discovered Bar's Stop Leak and what I used to fix the brand new heater core it clogged up. Have been using just tap water the last two fills. Water Filter Pitcher vs Faucet Filters: Which to Choose? While the ion exchange process results in high-quality, mineral-free water, there are other forms of water such as distilled water which is even purer. Re: Deionized vs Distilled Water for Radiator - 11/12/09 01:11 PM I use distilled water with my AF and engine internals stay clean. All minerals have been removed. But I thing you’re confusing deionized water with distilled water. I use distilled water with my AF and engine internals stay clean. Distilled water is distilled water. Yes, this is an old myth. If you have to replace water in your radiator often, then even distilled water will scale your radiator. While distilled water still lacks essential minerals that you usually get from water, it doesn’t rob your body of ions as it passes through you. It's an ion magnet. Deionized water is water that is acidic from the H+ ions. Normally change the fluid every year if not every two years. 1993 - So the bottle says to mix with deionized water? Distilled water is your water cooling friend. © Copyright 2021 TapItWater. The water is then condensed back into its liquid phase, so the resulting liquid is pure water – in fact, some of the purest water on earth. So, what separates these two types of purified water from each other? Distilled water is still very pure, but not to the level of deionized water that’s had all ions removed. Distilled water conducts electricity, whereas deionized water does not. To recap, both processes do purify water. Heating & Cooling. There was virtually no rust anywhere in the cooling system. The water will have a different taste and smell than other water since there are no substances present. Demineralised (deionized) water is useful for household appliances like irons and car radiators and if the research is right, that's probably the best way to use it, rather than drinking it. If you're keeping your cars for only 10 years then tap water may be okay. [However, radiator tubes being very thin (.013’’) the damage that can be done in a “few days” can be sufficient to damage the radiator. The mechanic there commented that he thinks people who use distilled water have cleaner radiators on average, based on what he sees brought in. So use either and the proper antifreeze and you will be fine. I replaced my water pump on my old 96 Merc GM when it had 190,000 miles( for preventive maintainance) and the inside of the pump and engine were spotless. The water is passed through a special resin that is charged to attract all molecules from the water. We do have good water here in the Rochester area. JavaScript is disabled. Hydrogen and hydroxyl molecules are exchanged in place of the ions being removed. Usually distilled water is purer (has more of its minerals and organisms removed) than deionized water. When should you choose one over the other and which one is the best choice for your health? Deionized vs Distilled Yes, this is an old myth. Distilled water vs Coolant: Which is the best product for your radiator? While distilled water offers very high purity, it may be contaminated when volatile materials rise away with the water vapor and end up in the distillate in what is known as carry-over. Deionized water, like distilled water, produces a pure form of water. However if the coolant user manual says to use distilled water I advice you to use distilled. The steam is then captured in a condenser. it's not acidic. When laboratory-grade water is necessary for medical work, food safety work, or lab testing, deionized water is used. When Should You Choose One Over the Other? Distilled water, especially if it's been double or triple distilled, can be used for nearly all laboratory applications, including those in which DI water might not be pure e… Deionized water, like distilled water, is a very pure form of water. Unlike the resin in water softeners, this resin cannot be regenerated and has a limited useful lifespan. You can put any kind of clean water in your car radiator, running water from your house’s faucet is OK, but if you have distilled water, it would be better. When the water is converted to steam, all impurities such as bacteria, sediment, and protozoa will be left behind. A fan will then cool the steam in the condenser, returning it once again to a liquid state. Featured image credit: PublicDomainPictures, Pixabay. Some benefit over it? Time travel due to flux capacitance?? As the drops of steam condense into water, they will pass through a final stage of filtration, a carbon postfilter. Deionized water is water that is acidic from the H+ ions. Distilled water is created by boiling water to rid it of contaminants and collecting the steam to condense it back into water. Distilled water can be purchased at any grocery store for about $1/gallon, and the distillation process removes all the thing sthat can cause problems with your cooling system including the salts and minerals. The other way around, distillation removes minerals and organic material. The minerals in regular water prevent toxic substances from accumulating, but since deionized water lacks these minerals, it can easily pick up plenty of toxins from any source. This makes it the best choice for situations like laboratory tests, cleaning industrial machinery, aquariums, and more. This means that it typically needs to be used in tandem with another type of treatment, such as Reverse Osmosis, to ensure that all contaminants are properly eliminated from it. (not sure what the mechanics use when he has had to drain the radiator. Of course, you wouldn’t want to drink deionized water.
