The short answer is no, you can’t mix tap water through engine coolant. Distilled water can work-related, but it is not ideal. Soft water is the best solution. We’ll get right into more detail listed below.

You are watching: A 50/50 blend of engine coolant and water

We all know the oil in our cars hregarding be readjusted, but it’s much less widespread expertise that the engine coolant requirements to be replaced as well.

At some point, the chemicals that circulation from our radiator and also into our engine block to proccasion overheating perform break down and end up being less and less efficient.

How frequently the coolant requirements to be reput is going to differ from car to auto. The typical is about eexceptionally 30,000 miles or eextremely few years.

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

This is a tall order considering the managed engine explosions that move your car forward acquire as much as roughly 495 levels F. These deserve to lead overall engine temperatures up into the 200-220 degree Fahrenheit variety when you are driving continuously.

To execute its task properly, the fluid that gets pumped via your engine and also avoids catastrophic heat damages MUST have actually a really low freezing point and a very high boiling point. Water alone does not meet these demands.

To satisfy these specifications, we usage a solution generally described as engine coolant. It is common for an additive referred to as antifreeze to be consisted of as part of this solution.

Pure antifreeze actually freezes and boils more easily than water, yet once linked, it actually lowers the freezing point of the mixture and also rises the boiling allude. It also stays clear of corrosion in your engine. Coolant is mainly a 1:1 ratio of antifreeze to water.

Why antifreeze though? Water freezes at 32 levels and also boils at 212 levels. Since engine temperatures have the right to sometimes drop listed below or exceed these varieties we need to use additives to proccasion the freezing and boiling of the fluids within the lines of your car’s radiator.

If that liquid were to freeze it would break your engine. If the fluid reaches a boiling point it will no much longer have the ability to serve as a warmth carry in between the warm metal in the engine block and also the vehicle will certainly overwarm.

Engine overheating causes warping of a number of vital components of the engine choose the aluminum cylinders, engine head gasket, and also water pump.

When water is blended with antifreeze (which is made of a chemical dubbed ethylene glycol), the freezing point is bumped dvery own to -35 degrees, and also the boiling suggest increased to 223 degrees Fahrenheit.

This renders ethylene glycol the perfect additive to our cooling system!

So currently we understand that mixing antifreeze and also water together make a perfect concoction for heat transport within the car’s cooling system, yet we must be particular on specifically what water to mix in via the antifreeze.

Tap Water Should Not Be Mixed With Antifreeze When Replacing Your Engine Coolant

Please save yourself the trouble dvery own the line. Do not use tap water as soon as it concerns your vehicle. While some engine coolants are designed to be blended via water before being poured right into the cooling device in your vehicle, you cannot simply use any kind of water that you please.

Tap water is full of minerals that will eventually form deposits inside your radiator, plumbing and water pump. This is also referred to as difficult water range.

This is all kinds of tap water that we are talking about here, no issue wright here you live! Tap water has actually mineral deposits in it by nature. You can’t put these minerals in your cooling device without bring about problems down the line.

When tap water is continuously supplied in your cooling mechanism you will begin to get a buildup of calcium and also magnesium. This buildup is also described as hard water scale and you’ve most likely viewed it on your family appliances.

When your radiator gets mineral buildup or difficult water range it becomes much less reliable at cooling off those hot engine components. And also simply a tiny buildup is a vast difficulty. A 1/16 of an inch of hard water scale will certainly make your cooling system 40% less efficient.

That means your engine is apt to get 40% hotter than it should be and also that have the right to cascade into many kind of other engine-related problems.

A much less efficient cooling mechanism can cause your engine overheating. When your engine overheats it can, and also if untreated will cause damages to your engine. Some engine components will certainly warp via the heat they are not intended to withstand.

Typical components that break and require repairs after engine overheating incorporate a cracked head gasket (average replacement expense $1500), warped cylinders (average replacement cost $500) and also water pump replacement ($350- $700).

A policy from Protect My Car can shield you from these high repair prices.

Needless to say it is much cheaper to be proenergetic and rearea your coolant with the proper ingredients prior to negligence or laziness leaves you without the convenience of your auto bereason it is in the shop undergoing a costly repair.

Since you are reading this article it’s pretty likely you’re wanting to replace your coolant yourself. It will probably expense you roughly $30 to complete this project. With the average cost of coolant repair at the mechanic being around $130 you’ll be conserving yourself $100 in labor costs from the mechanic. Go you!!

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

To reiterate. Tap water inside your engine block is bad! Do no not mix your antifreeze through tap water

Distilled Water Isn’t The Answer Either

There’s the majority of indevelopment on the internet that recommends making use of distilled water when it involves the cooling unit in your car. I’ve also checked out an extremely well known mechanic on YouTube placing distilled water in his cooling system!

The thought procedure right here is that distilled water has actually had the minerals stripped from it and will certainly not leave build-up deposits in your hoses and radiator.

While this is good in theory what this does not take right into account is the distillation procedure. Here’s why you have to NOT usage distilled water.

When distilling, the water is heated right into a gaseous phase. When this water boils off and evapoprices it leaves behind the calcium and magnesium that once lived between it’s molecules. This procedure is called mineral stripping.

While we carry out require water that has been removed of these minerals for the coolant mechanism, the procedure of distillation actually will certainly leave the water ionically imwell balanced. Essentially the distilled water solution is unsteady bereason it is absent an electron. Distilled water will certainly damages the metals in your engine if provided consistently.

The Science Behind Why This Works

As the water evaporates, the calcium and also magnesium take through them electrons leaving the continuing to be solution yearning to rebalance itself and get a full collection of eight valence electrons.

When you put distilled water inside your engine block that water will certainly carry out its best to strip electrons from the metals it comes in contact with.

Basically the gist of this without all the subatomic jargon is that distilled water is still damaging to the components of your engine simply in a different way than tap water.

So steer clear of distilled water as well as tap water despite what a lot of civilization are posting digital.

Use Softened Water For Best Results

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

The process of water softening takes tap water and also clears the minerals within it. The major minerals in tap water are calcium and magnesium and also tright here are additionally trace amounts of iron depending on wbelow you live.

So, softened water, like distilled water, is cost-free of calcium and also magnesium. However before, the procedure of removal of these minerals is vastly different. And that renders all the distinction. Here’s why.

The large distinction in between these procedures is as minerals are rerelocated in the softening operation they are reput via a sodium ion. The solution that outcomes right here is stable, it’s not trying to take electrons from substances it comes in call through. This renders softened water safe to usage, as it won’t ruin the internal devices of your automobile.

Softened water, unfavor distilled water, won’t strip the steels in your engine block of their electrons, which have the right to cause damage to your engine. With the average engine repair expense sitting at roughly $3,500 dollars, it pays to be prudent. Be prudent and also spfinish the added time obtaining soft water next time you have to make a repair on your car.

Softened water is completely safe to put in your engine and also won’t reason damages, unlike tap water or distilled water. So be smart. Stick to soft water!!

You Can Either Make Soft Water Yourself – Or Buy A Water Softener

So now that you’re aware of the fact that you should have actually soft water to mix in via your antifreeze let’s talk around wright here you can gain it.

Your tap if you have a water softener. You deserve to gain among these from Amazon/Home Depot/WalmartYou can make your very own making use of the process comprehensive belowAsk your household or friends who live adjacent if they have a water softener device installed in their residence. If they carry out and agree to provide you some of their water, you deserve to lug gallon jugs or another water deliver container, fill them up from the tap at their residence. I would verify that the water is actually softened.

Unfortunately from my research I haven’t been able to uncover soft water bottled that you deserve to purchase virtual. What I did find was distilled water claiming to be soft being retailed. Please don’t buy distilled water pretending to be soft water. Tright here is a distinction, don’t let the water suppliers fool you by claiming they have soft distilled water.

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

How to make your own softened water without installing a water softener in your home

Bring your water to a boil.Next enable the water to cool. If your water is temporarily difficult meaning it has bicarbonate and calcium ions then you are good to go and the boiling procedure will certainly deal with this problem. For a lot of of you the water is permanently tough, in other words it consists of calcium and magnesium sulfates. If your water is permanently difficult, continue to action 2 once the boiled water has cooled.Add washing soda to your water. Washing soda, which is similar to baking soda deserve to be uncovered and purchased at many huge retailers favor Walmart or Tarobtain in the laundry area. For precise mixing proparts check the packaging of the washing soda.

Coolant or Antifreeze? Which Should I Combine With My Soft Water?

Antifreeze and engine coolant are supplied interchangeably, yet they are not specifically the very same thing. Let’s resolve this confusion.

Engine coolant describes the liquid blended solution that surges with the engine block in your vehicle maintaining it from overheating. Basically precisely as its name describes. It is crucial to note that it is a solution, definition it is consisted of of a mix of numerous substances.

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

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

To reiterate, your alternatives here are to purchase a premixed engine coolant that is ready to be added to your empty, clean, engine coolant compartment in your vehicle. Or you have the right to purchase anti-freeze and also mix a 1:1 ratio through softened water. Almethods review the mixing instructions to verify security measures and mixing ratios which might vary from brand to brand also.

I have actually included some information even more alengthy in this short article to aid you clean out your engine coolant system of all old, offered and dirty coolant and to assist you dispose of it effectively.

REMEMBER antifreeze is toxic and hregarding be disposed of properly! Please be sure to save your used and replacement coolant away from pets it tastes sweet to them and also they will drink it.

You Don’t Have To Mix All Coolants With Water

Now that we understand the standard differences in between engine coolant and antifreeze this question is much even more controlled.

Some engine coolant will come preblended from the store and is all set to be added to your automobile as is. It does not have to be included to water. If you are not sure if you have purchased a premixed engine coolant, examine the instructions on the label.

To identify what kind of engine coolant your car needs describe your car’s owner hands-on. Generally your vehicle will certainly be labeled close to the fill spot too showing what shade of engine coolant is recommfinished. They are traditionally green or oarray.

Antifreeze is a pure substance that does have to be combined through equal components water to make an acceptable engine coolant. What type of water everyone?? SOFT WATER.

Please examine the manufacturer’s instructions once mixing antifreeze before including the liquid to your vehicle. Be certain to follow all safety and security prealerts thorough by the manufacturer as well. Remember that this stuff is toxic and also have the right to kill mammals that drink it.

Why Do We Add Antifreeze To The Water We Use To Cool Our Engine?

Water is corrosive and will certainly inevitably corrode the engine and cause rusting of the interior components it comes in call with making them unable to do their job.Water has actually a reasonably low freezing suggest, however in many locations of the human being winter does obtain cold sufficient to lug fresh water to a solid ice. If this wregarding occur within a auto it would certainly break the engine.Coolant also keeps the water from boiling when it gets as well hot. When engine coolant boils, or any type of various other liquid for that matter it cannot acquire any kind of hotter while in the liquid develop. What this means is that it is no longer reliable at receiving warmth from your engine or cooling anypoint down.Basically coolant protects your car’s cooling mechanism when driving in extreme weather climates. So if you’re planning on adventuring towards the poles in your auto or driving with fatality valley you have to make sure your cars coolant levels are complete and also have been combined with the appropriate coolant for your vehicle

What Happens When You Add Water To Antifreeze?

The properties of water shift once creating a solution via antifreeze. The temperature at which it boils increases. This renders it better at withstanding warm and also consequently enhances its capability to cool dvery own what it comes in contact through.

Water is an excellent conductor interpretation it receives energy, or warm, well. When you add antifreeze to the mix it becomes also better at conducting by nature of the boiling allude increasing.

Basically the liquid solution deserve to retain even more heat prior to being converted into a gaseous state. Layman’s terms here is that the solution containing antifreeze is much better at cooling down the hot engine components as soon as it runs via your engine blocks.

Antifreeze is additionally a carrier for a number of additives that reduce the solutions corrosive results. These additives might incorporate yet are not limited to sodium silicate (an aluminum anticorrosive) and antifoaming agents.

You want to constantly review the manufacturer’s instructions to see exactly how and also if you should mix coolant through water.

It’s likewise important to note that antifreeze is exceptionally dangerous to pets. It is enticing to dogs and cats bereason it tastes sweet to them. They will certainly attempt to drink it if provided the opportunity and it is normally deadly.

Make Sure You Dispose Of Your Antifreeze Properly

Be careful via your provided engine liquid throughout the removal process as it is toxic and need to not ssuggest be dumped out via the trash or down a drainpipe.

It demands to be disposed of effectively. Be sure to transfer the liquid into something watertight. It needs to be in a container that will certainly be feasible to put in your automobile to take in for recycling.

Used engine coolant can be effectively disposed of pretty quickly. Most mechanics will take it off your hands for cost-free (they make money once they offer it off to the disposal companies).

You have the right to also recycle the liquid at your regional disposal center or hire a personal waste disposal company to come pick it up from you.

I reiterate below, engine coolant is toxic. We carry out not want it in our water units, in our pets or in our kids. That would certainly be poor. Be responsible.

What Type of Engine Coolant Should I Use?

Wouldn’t it be lovely if most auto manufacturers used a continuous type of engine coolant? Well they don’t and I recommfinish checking your car’s user hands-on to discover the manufacturer’s recommended type of engine coolant. From there you can choose a brand or generic amongst this category of coolant.

Tbelow are three prevalent ranges of engine coolant: they are not natural additive innovation, organic acid innovation and also finally hybrid organic acid innovation.


This solution a bit outdated and also is less exceptional than its competitors nowadays. As tright here are currently even more reliable alternatives on the engine coolant market you commonly just see not natural additive innovation in older vehicles.

If your auto supplies this type of engine coolant it is necessary that you stay on top of flushing your system and also replacing your coolant.

Inorganic additive modern technology coolant have to be changed eincredibly 24,000 miles or two years, whichever comes initially. This is far more frequent than more recent coolants that are on the industry.


The next coolant we are going to comment on is a lot even more with the times and also needs far less maintenance and also upkeep. It is significantly popular in vehicles more recent than the year 2000.

Organic acid modern technology coolant, which is commonly provided by General Motors, just requirements to be adjusted eexceptionally five years or 150,000 miles! That is a remarkably lengthy size of time that you deserve to go without replacing your coolant. This conserves these automobile owners time and also money associated via maintenance measures.

This selection of OAT coolant is traditionally orange yellow in shade, but not always.

It is derived using fully neutralized organic acids and also azoles and these are the components that make the fluid anti corrosive. This is also wright here the substance got its name.


Finally we have actually Hybrid Organic Acid Technology which is a slight variation of Organic Acid Technology. Both of these coolants have essentially similar replacement cycles

Change The Fluids In Your Cooling System Eincredibly 30,000 Miles

At some point the chemicals in antifreeze do breakdown and come to be less efficient at maintaining your car’s temperatures modeprice. When this happens your car is at higher danger of engine overheating which can lead to costly repairs.

Its ideal to be proenergetic below and also change this antifreeze combination eextremely 30,000 miles or so for many vehicles. Your car’s user manual have to make a referral on this mileage specific to your automobile in the very same area wright here they detail what

What The Color Of Your Anti-Freeze Means

Until incredibly newly the the majority of frequently used color of antifreeze was a neon green. This is because this is the shade that is associated with the variety of coolant dubbed Inorganic Additive Technology or IAT.

IAT has been on the decline as the choice of vehicle manufacturers sindicate because there are now even more efficient coolants on the market. Increasing in popularity are orange and red coolants which are typically of the Organic Acid Technology selection of coolant.

While these types of coolants are traditionally these colors you have to constantly verify that you are making use of the appropriate coolant for your car making use of your owners hand-operated of your auto.

Nowadays coolant shade doesn’t expect as much as it used to. The objective of providers that manufacture engine coolant dying their commodities is for marketing objectives and also safety and security concerns.

Antifreeze is by nature clear. By making it a ghastly bappropriate shade it does a couple things. It makes the substance straightforward to identify as soon as compared to water.

This is super vital because remember antifreeze is incredibly toxic. If you, your household members or friends or your pets were to drink it it deserve to be deadly. Contact a poiboy facility or go to the emergency room if you think you’ve accidentally consumed this stuff.

Antifreeze suppliers have the right to include whatever before color dye they would like to their product. For this factor I encourage my readers not to use color alone as a means to identify the range of antifreeze that is excellent for your automobile.

Can you use battery water as a coolant or various other substitutes?

It counts on what you consider to be “battery water”.

Some individuals refer to battery water once talking around the liquid within automobile batteries dubbed electrolyte. Electrolyte is a mixture of sulfuric acid and pure water. It have to never before be added to the coolant mechanism in your car. Please execute not drain your battery right into your cooling system.

To others the term battery water refers to the water that you add to your battery. This water is simply distilled water.

Putting distilled water in your radiator is a mainly welcomed practice however I encourage people to opt for soft water over distilled water. My thinking here is that soft water has actually a complete collection of valence electrons whereas distilled water does not.

Basically that means that soft water will not spilgrimage the steel in your engine block in the exact same way that distilled water will certainly. If you are puzzled by this I cover more on the scientific research behind distilled water and soft water towards the start of this article.

Opt for soft water over distilled water. Whatever you carry out though, don’t drainpipe battery fluid into your automobile. I’m willing to bet it will go poorly for you and your vehicle.

How to safely and also properly drain and also flush your cooling system

Most of my readers are interested in engine coolant bereason they are proactively undertaking the replacement of their engine coolant themselves. This is awesome and also will conserve you males some money, however, you need to make certain you are replacing the fluid effectively and also specifically that you dispose of your old coolant in a responsible fashion.
