The short answer is no, friend can’t mix tap water through engine coolant. Distilled water have the right to work, however it is no ideal. Soft water is the finest solution. We’ll gain into much more detail below.

You are watching: What kind of water do you mix with antifreeze

We all recognize the oil in our cars needs to be changed, but it’s less common knowledge that the engine coolant requirements to be replaced as well.

Eventually, the chemicals that flow from our radiator and into our engine block to prevent overheating do break down and end up being less and also less effective.

How commonly the coolant demands to be changed is walking to vary from vehicle to vehicle. The traditional is about every 30,000 mile or every few years.

So what is engine coolant exactly? Engine coolant is the liquid that surges with your engine and keeps your vehicle from overheating.

This is a high order considering the controlled engine explosions that relocate your vehicle forward get up to around 495 degrees F. These have the right to lead all at once engine temperature up right into the 200-220 degree Fahrenheit variety when you space driving continuously.

To perform its task properly, the fluid that it s okay pumped with your engine and also prevents catastrophic heat damages MUST have a really low freezing point and a very high boiling point. Water alone does not accomplish these requirements.

To fulfill these specifications, we use a solution commonly referred to together engine coolant. It is common for an additive called antifreeze come be contained as part of this solution.

Pure antifreeze actually freezes and also boils more quickly than water, however when combined, it in reality lowers the freezing suggest of the mixture and also increases the cook point. It likewise prevents corrosion in your engine. Coolant is normally a 1:1 ratio of antifreeze to water.

Why antifreeze though? Water freezes at 32 degrees and also boils in ~ 212 degrees. Since engine temperatures can sometimes drop below or exceed these arrays we must use additives to protect against the freezing and boiling the the fluids within the lines of her car’s radiator.

If that liquid were to frozen it would break her engine. If the liquid reaches a boiling suggest it will certainly no longer have the ability to serve as a heat transfer in between the hot metal in the engine block and the vehicle will overheat.

Engine overheating reasons warping of number of important contents of the engine choose the aluminum cylinders, engine head gasket, and water pump.

When water is blended with antifreeze (which is make of a chemical dubbed ethylene glycol), the freezing suggest is bumped under to -35 degrees, and also the boiling allude raised to 223 degrees Fahrenheit.

This makes ethylene glycol the perfect additive come our cooling system!

So currently we understand that mixing antifreeze and water with each other make a suitable concoction for heat transfer within the car’s cooling system, however we need to be particular on precisely what water to mix in through the antifreeze.

Tap Water must Not Be combined With Antifreeze when Replacing her Engine Coolant

Please conserve yourself the trouble down the line. Carry out not use tap water once it comes to your vehicle. While some engine coolants are designed to be blended with water before being poured into the cooling mechanism in your vehicle, friend cannot just use any type of water the you please.

Tap water is full of mineral that will eventually kind deposits inside your radiator, plumbing and water pump. This is additionally referred come as difficult water scale.

This is all types of tap water that we space talking about here, no matter where girlfriend live! madness water has actually mineral deposits in the by nature. You can’t put these mineral in her cooling mechanism without causing troubles down the line.

When insanity water is repeatedly offered in your cooling mechanism you will begin to obtain a buildup the calcium and magnesium. This accumulation is additionally referred to as difficult water scale and also you’ve likely seen that on your family appliances.

When your radiator it s okay mineral buildup or hard water range it becomes less reliable at cooling turn off those warm engine parts. And even just a little build-up is a vast problem. A 1/16 the an inch of difficult water range will make her cooling system 40% much less effective.

That means your engine is apt to gain 40% hotter than it need to be and that can cascade into countless other engine-related issues.

A less efficient cooling system deserve to lead to her engine overheating. As soon as your engine overheats that can, and if untreated will cause damage to her engine. Some engine parts will warp v the warm they room not supposed to withstand.

Common components that break and also require repair after engine overheating include a cracked head gasket (average replacement expense $1500), warped cylinders (average replacement expense $500) and water pump instead of ($350- $700).

A policy from protect My auto can shield you from this high fix costs.

Needless to say it is much cheaper to it is in proactive and also replace her coolant v the suitable ingredients before negligence or laziness leaves you without the convenience the your automobile because the is in the shop undergoing a i have lot of money repair.

Since friend are reading this article it’s pretty most likely you’re wanting to change your coolant yourself. It will probably cost you approximately $30 to finish this project. Through the average cost of coolant fix at the mechanic being roughly $130 you will do it be saving yourself $100 in labor prices from the mechanic. Walk you!!

If you’re trying come learn more about the ins and outs of changing your engine coolant yourself, there’s more on the to come, therefore bear through me.

To reiterate. Madness water inside her engine block is bad! do no not mix your antifreeze v tap water

Distilled Water Isn’t The price Either

There’s a many of information on the internet that recommends using distilled water when it pertains to the cooling unit in your vehicle. I’ve also seen a really famous mechanic top top YouTube placing distilled water in his cooling system!

The thought procedure here is the distilled water has had the minerals stripped indigenous it and also will no leave build-up deposits in her hoses and radiator.

While this is an excellent in concept what this does no take into account is the distillation process. This is why you must NOT use distilled water.

When distilling, the water is heated right into a gas phase. When this water boils off and evaporates it pipeline behind the calcium and magnesium that once lived in between it’s molecules. This process is referred to as mineral stripping.

While we do need water that has been removed of this minerals for the coolant system, the procedure of distillation actually will leave the water ionically imbalanced. Essentially the distilled water solution is unstable since it is lacking an electron. Distilled water will damage the metals in your engine if offered repeatedly.

The science Behind Why This Works

As the water evaporates, the calcium and magnesium take with them electron leaving the remaining solution yearning to rebalance itself and gain a full set of eight valence electrons.

When you placed distilled water inside your engine block that water will execute its best to strip electrons from the metals it come in call with.

Essentially the gist the this without all the subatomic jargon is that distilled water is quiet damaging to the materials of her engine simply in a different means than madness water.

So steer clear of distilled water as well as tap water regardless of what most civilization are posting online.

Use Softened Water For best Results

Softened water is the anwer right here – it makes a difference.

The procedure of water softening takes tap water and also removes the minerals in ~ it. The key minerals in insanity water space calcium and magnesium and there are likewise trace quantities of iron relying on where friend live.

So, softened water, like distilled water, is complimentary of calcium and also magnesium. However, the procedure of removed of this minerals is vastly different. And that makes all the difference. Here’s why.

The large distinction between these procedures is as minerals are removed in the softening procedure they are changed with a sodium ion. The systems that results below is stable, it’s no trying to take it electrons from substances it come in call with. This renders softened water for sure to use, together it won’t damage the inner systems of her vehicle.

Softened water, uneven distilled water, won’t strip the steels in her engine block of your electrons, i m sorry can reason damage to her engine. With the mean engine repair cost sitting at about $3,500 dollars, it payment to be prudent. Be prudent and spend the extra time acquiring soft water next time you need to make a fix on your car.

Softened water is completely safe to placed in your engine and won’t reason damage, uneven tap water or distilled water. So it is in smart. Stick to soft water!!

You deserve to Either do Soft Water you yourself – Or to buy A Water Softener

So now that you’re mindful of the truth that you require to have soft water come mix in with your antifreeze stop talk about where friend can obtain it.

Your insanity if you have actually a water softener. You can get one of these from Amazon/Home Depot/WalmartYou have the right to make your very own using the procedure detailed belowAsk your household or friends who live nearby if they have a water softener system mounted in your home. If lock do and agree to give you some of their water, you can carry gallon jugs or an additional water deliver container, fill them up from the madness at your home. I would verify that the water is actually softened.

Unfortunately native my study I haven’t to be able to find soft water bottled that you can purchase online. What ns did uncover was distilled water claiming to it is in soft gift retailed. You re welcome don’t buy distilled water pretending to it is in soft water. Over there is a difference, nothing let the water suppliers fool girlfriend by declare they have soft distilled water.

LUCKILY you can make softened water pretty easily at home. Here’s how.

How to make your own softened water there is no installing a water softener in her home

Bring her water to a boil.Next allow the water come cool. If her water is temporary hard definition it has bicarbonate and also calcium ion then girlfriend are good to go and the boiling procedure will solve this problem. For most of girlfriend the water is permanently hard, in other words it contains calcium and also magnesium sulfates. If her water is permanently hard, proceed to step two once the boiled water has actually cooled.Add washing soda to her water. Washing soda, i m sorry is comparable to baking soda can be found and also purchased in ~ most huge retailers like Walmart or Target in the laundry section. For specific mixing proportions inspect the packaging the the washing soda.

Coolant or Antifreeze? Which have to I combine With mine Soft Water?

Antifreeze and also engine coolant are used interchangeably, however they room not precisely the exact same thing. Let’s settle this confusion.

Engine coolant refers to the liquid mixed solution that surges through the engine block in your vehicle keeping that from overheating. Basically exactly as its name describes. The is vital to note that it is a solution, definition it is consisted of of a mix of number of substances.

Antifreeze is a chemical, ethylene glycol, which is uncovered in most premixed engine coolants that are all set to be added to your vehicle.

It is also sold individually as a pure substance ready to be blended with SOFTENED WATER and then funneled into your car’s cooling device (after you have actually read the manufacturer’s instructions and safety warnings).

To reiterate, your choices here space to purchase a premixed engine coolant the is ready to be included to her empty, clean, engine coolant compartment in her car. Or you can purchase anti-freeze and mix a 1:1 ratio with softened water. Always read the mixing instructions come verify safety procedures and also mixing ratios which may vary indigenous brand come brand.

I have consisted of some information more along in this short article to assist you clean out your engine coolant device of all old, used and dirty coolant and to aid you dispose of the properly.

REMEMBER antifreeze is toxic and also has to it is in disposed that properly! please be sure to save your used and also replacement coolant far from pets it tastes sweet to them and they will certainly drink it.

You Don’t have to Mix all Coolants through Water

Now that we understand the basic differences in between engine coolant and also antifreeze this question is much much more manageable.

Some engine coolant will come premixed from the store and also is prepared to be added to your automobile as is. That does not need to be included to water. If you space not sure if you have purchased a premixed engine coolant, inspect the indict on the label.

To identify what form of engine coolant your car requires refer to your car’s owner manual. Generally your auto will it is in labeled near the to fill spot too showing what shade of engine coolant is recommended. They space traditionally green or orange.

Antifreeze is a pure substance the does need come be combined with equal parts water to do an agree engine coolant. What form of water everyone?? SOFT WATER.

Please inspect the manufacturer’s instructions when mixing antifreeze before adding the fluid to your vehicle. Be certain to follow all safety and security precautions detailed by the manufacturer together well. Remember that this ingredient is toxic and can kill mammals the drink it.

Why execute We add Antifreeze to The Water We usage To Cool our Engine?

Water is corrosive and also will at some point corrode the engine and cause rusting of the internal contents it comes in call with making them unable to do their job.Water has a fairly low freezing point, however in most locations of the human being winter does obtain cold enough to carry fresh water to a hard ice. If this to be to take place within a automobile it would certainly break the engine.Coolant additionally keeps the water from boiling as soon as it gets too hot. Once engine coolant boils, or any other liquid for that issue it can not get any hotter when in the fluid form. What this way is the it is no longer effective at receiving heat from her engine or cooling noþeles down.Essentially coolant protects her car’s cooling mechanism when control in excessive weather climates. Therefore if you’re planning top top adventuring towards the poles in your auto or control through fatality valley you have to make certain your car coolant levels space full and have been blended with the suitable coolant for your vehicle

What Happens when You include Water come Antifreeze?

The nature of water change when creating a equipment with antifreeze. The temperature at which it boils increases. This makes it far better at withstanding heat and in turn improves its capacity to cool under what it comes in contact with.

Water is an excellent conductor definition it obtain energy, or heat, well. Once you include antifreeze come the mix it i do not care even far better at conducting by nature that the boiling suggest increasing.

Essentially the fluid solution have the right to retain more heat before being converted into a gas state. Layman’s terms below is that the solution containing antifreeze is better at cooling down the warm engine parts as soon as it runs through your engine blocks.

Antifreeze is also a transport for several additives that minimize the remedies corrosive effects. This additives may include but are not restricted to sodium silicate (an aluminum anticorrosive) and also antifoaming agents.

You desire to constantly read the manufacturer’s accuse to watch how and if you need to mix coolant through water.

It’s additionally important to keep in mind that antifreeze is an extremely dangerous come animals. That is enticing come dogs and also cats since it tastes sweet come them. Castle will shot to drink the if provided the chance and it is usually deadly.

Make certain You Dispose Of your Antifreeze Properly

Be mindful with your supplied engine fluid throughout the removal process as the is toxic and should not just be dumped out through the rubbish or down a drain.

It requirements to be disposed of properly. Be certain to deliver the liquid right into something watertight. It requirements to it is in in a container that will certainly be feasible to put in your auto to take in because that recycling.

Used engine coolant deserve to be appropriately disposed of nice easily. Many mechanics will take the off your hands for totally free (they do money as soon as they offer it off to the disposal companies).

You can likewise recycle the liquid at your neighborhood disposal center or hire a exclusive waste disposal company to come choose it increase from you.

I reiterate here, engine coolant is toxic. We execute not want it in ours water systems, in our pets or in our children. That would be bad. It is in responsible.

What kind of Engine Coolant should I Use?

Wouldn’t it be lovely if most vehicle manufacturers used a consistent kind of engine coolant? well they don’t and also I recommend checking your car’s user manual to find the manufacturer’s recommended kind of engine coolant. From there you can choose a brand or generic amongst this group of coolant.

There are three common varieties that engine coolant: lock are not natural additive technology, necessary acid an innovation and lastly hybrid organic acid technology.


This solution a little outdated and is less superior 보다 its competitors nowadays. Together there are now much more effective choices on the engine coolant market you frequently only see inorganic additive modern technology in enlarge vehicles.

If your vehicle uses this form of engine coolant it is necessary that you stay on peak of flushing your system and replacing her coolant.

Inorganic additive an innovation coolant must be readjusted every 24,000 miles or 2 years, whichever comes first. This is far much more frequent than more recent coolants that space on the market.


The next coolant we are going to comment on is much an ext with the times and requires far less maintenance and upkeep. The is increasingly well-known in vehicles newer than the year 2000.

Organic acid technology coolant, i beg your pardon is widely used by basic Motors, only demands to be readjusted every 5 years or 150,000 miles! that is a substantial long size of time that you can go without replacing your coolant. This conserves these vehicle owners time and money associated with maintain procedures.

This range of OAT coolant is traditionally orange yellow in color, however not always.

It is acquired using fully neutralized organic acids and azoles and also these space the contents that do the fluid anti corrosive. This is also where the substance received its name.


Finally we have Hybrid necessary Acid an innovation which is a slim variation the Organic mountain Technology. Both of this coolants have essentially equivalent replacement cycles

Change The Fluids In your Cooling device Every 30,000 Miles

Eventually the chemicals in antifreeze do break down and become less reliable at keeping your car’s temperature moderate. When this wake up your car is at better risk that engine overheating which have the right to lead to i have lot of money repairs.

Its best to be proactive here and adjust this antifreeze mix every 30,000 miles or so for most vehicles. Your car’s user hand-operated should make a recommendation on this mileage specific to your vehicle in the same section whereby they information what

What The shade Of your Anti-Freeze Means

Until an extremely recently the most generally used shade of antifreeze to be a neon green. This is because this is the shade that is associated with the selection of coolant dubbed Inorganic Additive modern technology or IAT.

IAT has actually been ~ above the decline as the an option of car manufacturers simply due to the fact that there space now more effective coolants ~ above the market. Enhancing in popularity are orange and red coolants i m sorry are generally of the essential Acid modern technology variety the coolant.

While these species of coolants are traditionally this colors friend should always verify that you space using the suitable coolant for your vehicle using your owners hands-on of her vehicle.

Nowadays coolant shade doesn’t mean as much as it provided to. The purpose of suppliers who to produce engine coolant dying their products is for marketing purposes and safety concerns.

Antifreeze is by nature clear. By making that a ghastly bright shade it go a pair things. It makes the substance straightforward to determine when compared to water.

This is super important due to the fact that remember antifreeze is really toxic. If you, your household members or friend or your pets were come drink the it deserve to be deadly. Contact a poison center or go to the emergency room if you think you’ve accidentally consumed this stuff.

Antifreeze carriers can include whatever shade dye they would favor to your product. For this reason I encourage my readers not to use color alone as a means to identify the range of antifreeze the is good for her car.

Can you usage battery water together a coolant or various other substitutes?

It depends on what you take into consideration to it is in “battery water”.

Some people refer come battery water when talking around the fluid within car batteries called electrolyte. Electrolyte is a mixture that sulfuric acid and pure water. It have to never be included to the coolant device in her car. Please execute not drain your battery right into your cooling system.

To rather the hatchet battery water refers to the water that you include to your battery. This water is just distilled water.

Putting distilled water in your radiator is a generally embraced practice yet I encourage civilization to opt for soft water end distilled water. Mine reasoning below is the soft water has actually a full set of valence electron whereas distilled water walk not.

Essentially that means that soft water will certainly not strip the steel in your engine block in the same means that distilled water will. If you are confused by this i cover an ext on the science behind distilled water and soft water towards the beginning of this article.

Opt because that soft water over distilled water. Whatever you carry out though, don’t drain battery fluid into your car. I’m willing to bet it will go poorly for you and also your car.

How come safely and effectively drain and flush her cooling system

Most of my readers room interested in engine coolant due to the fact that they are actively undertaking the replacement of your engine coolant themselves. This is awesome and also will conserve you guys some money, however, you need to make certain you room replacing the liquid properly and especially the you dispose of her old coolant in a responsible fashion.
