The quick answer is no, you can’t mix tap water with engine coolant. Distilled water have the right to work, but it is not ideal. Soft water is the best solution. We’ll gain into an ext detail below.

You are watching: Can you put water in coolant tank

We all know the oil in our cars needs to be changed, yet it’s less usual knowledge the the engine coolant requirements to be changed as well.

Eventually, the chemicals that flow from ours radiator and also into ours engine block to protect against overheating do malfunction and end up being less and also less effective.

How frequently the coolant requirements to be changed is walking to differ from auto to vehicle. The conventional is about every 30,000 miles or every couple of years.

So what is engine coolant exactly? Engine coolant is the liquid that surges through your engine and also keeps your automobile from overheating.

This is a high order considering the controlled engine explosions that relocate your vehicle forward obtain up to roughly 495 degrees F. These deserve to lead in its entirety engine temperature up into the 200-220 degree Fahrenheit variety when you space driving continuously.

To perform its job properly, the liquid that it s okay pumped with your engine and prevents catastrophic heat damages MUST have a really low freezing suggest and a really high boiling point. Water alone walk not satisfy these requirements.

To fulfill these specifications, we usage a solution generally referred to as engine coolant. It is common for an additive dubbed antifreeze come be contained as part of this solution.

Pure antifreeze in reality freezes and boils an ext quickly than water, yet when combined, it actually lowers the freezing suggest of the mixture and also increases the boiling point. It additionally prevents corrosion in her engine. Coolant is normally a 1:1 ratio of antifreeze to water.

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

If the liquid to be to freeze it would certainly break your engine. If the fluid reaches a boiling point it will certainly no longer be able to serve together a heat transfer in between the hot metal in the engine block and the auto will overheat.

Engine overheating reasons warping of several important materials 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 down to -35 degrees, and also the boiling point raised come 223 degrees Fahrenheit.

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

So currently we understand that mix antifreeze and water with each other make a perfect concoction for heat transfer in ~ the car’s cooling system, yet we have to be details on exactly what water to mix in v the antifreeze.

Tap Water must Not Be blended With Antifreeze once Replacing her Engine Coolant

Please save yourself the trouble down the line. Execute not usage tap water once it involves your vehicle. While part engine coolants room designed to be blended with water before being poured into the cooling device in your vehicle, you cannot just use any type of water that you please.

Tap water is full of minerals that will eventually form deposits inside her radiator, plumbing and also water pump. This is likewise referred come as hard water scale.

This is all species of insanity water that we are talking around here, no matter where you live! insanity water has actually mineral store 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 start to obtain a buildup the calcium and magnesium. This buildup is likewise referred come as difficult water scale and also you’ve most likely seen that on your household appliances.

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

That way your engine is apt to gain 40% hotter 보다 it have to be and also that deserve to cascade into many other engine-related issues.

A less reliable cooling system have the right to lead to her engine overheating. When your engine overheats the can, and if untreated will cause damage to your engine. Part engine components will warp v the warmth they room not intended to withstand.

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

A plan from defend My vehicle can shield girlfriend from these high fix costs.

Needless to say the is much cheaper to be proactive and replace her coolant through the ideal ingredients prior to negligence or laziness leaves you without the convenience of your car because the is in the shop undergoing a i have lot of money repair.

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

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

To reiterate. Madness water inside your engine block is bad! perform no no mix her antifreeze with tap water

Distilled Water Isn’t The prize Either

There’s a lot of info on the net that recommends making use of distilled water once it involves the cooling unit in your vehicle. I’ve even seen a an extremely famous mechanic on YouTube putting distilled water in his cooling system!

The thought procedure here is that distilled water has had actually the minerals stripped from it and will no leave build-up deposits in your hoses and radiator.

While this is good in concept what this does no take right 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. As soon as this water boils off and evaporates it leaves behind the calcium and also magnesium that once lived in between it’s molecules. This process is called mineral stripping.

While we do need water that has been eliminated of these minerals for the coolant system, the procedure of distillation actually will certainly leave the water ionically imbalanced. Essentially the distilled water solution is unstable because it is absent an electron. Distilled water will damage the steels in her engine if offered repeatedly.

The scientific research Behind Why This Works

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

When you placed distilled water inside your engine block the water will perform its ideal to strip electrons indigenous the steels it comes in contact with.

Essentially the gist that this without every the subatomic slang is that distilled water is still damaging to the materials of your engine just in a different method than insanity water.

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

Use Softened Water For ideal Results

Softened water is the anwer below – it provides a difference.

The procedure of water softening takes tap water and also removes the minerals in ~ it. The main minerals in tap water room calcium and also magnesium and also there are also trace quantities of iron depending upon where girlfriend live.

So, softened water, like distilled water, is free of calcium and magnesium. However, the procedure of remove of these minerals is vastly different. And also that provides all the difference. Here’s why.

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

Softened water, uneven distilled water, won’t strip the metals in your engine block of their electrons, which can reason damage to your engine. With the average engine repair price sitting at around $3,500 dollars, it payment to be prudent. It is in prudent and also spend the extra time acquiring soft water next time you must make a fix on her car.

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

You can Either make Soft Water you yourself – Or buy A Water Softener

So now that you’re conscious of the truth that you require to have soft water come mix in through your antifreeze let’s talk about where girlfriend can gain it.

Your madness if you have a water softener. Girlfriend can acquire one of these from Amazon/Home Depot/WalmartYou have the right to make your own using the procedure detailed belowAsk your family or friends who live adjacent if they have a water softener system set up in their home. If they do and also agree to give you some of their water, girlfriend can bring gallon jugs or another water carry container, fill them increase from the madness at your home. I would verify that the water is in reality softened.

Unfortunately from my study I haven’t been able to find soft water bottled that you deserve to purchase online. What ns did discover was distilled water explain to be soft being retailed. Please don’t purchase distilled water pretending to be soft water. There is a difference, don’t let the water suppliers fool girlfriend by claiming they have soft distilled water.

LUCKILY you have the right to make softened water pretty easily at home. Here’s how.

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

Bring your water to a boil.Next allow the water come cool. If her water is temporarily hard meaning it contains bicarbonate and also calcium ions then you are great to go and the boiling process will fix this problem. For most of girlfriend the water is permanently hard, in various other words it consists of calcium and also magnesium sulfates. If your water is permanently hard, continue to step two when the boiled water has actually cooled.Add washing soda to her water. Washing soda, i m sorry is similar to baking soda have the right to be found and also purchased at most large retailers like Walmart or Target in the to wash section. For precise mixing proportions check the packaging that the washing soda.

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

Antifreeze and engine coolant are offered interchangeably, yet they space not precisely the exact same thing. Let’s clear up this confusion.

Engine coolant describes the liquid blended solution the surges with the engine block in your auto keeping it from overheating. Essentially exactly as its name describes. The is essential to keep in mind that that is a solution, meaning it is made up of a mix of several substances.

Antifreeze is a chemical, ethylene glycol, i m sorry is uncovered in most premixed engine coolants that are ready to be included to her vehicle.

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

To reiterate, your choices here are to purchase a premixed engine coolant the is prepared to be added to her empty, clean, engine coolant compartment in your car. Or you can purchase anti-freeze and also mix a 1:1 proportion with softened water. Constantly read the mix instructions come verify safety and security procedures and mixing ratios which might vary from brand to brand.

I have had some information more along in this write-up to assist you clean out your engine coolant mechanism of every old, used and dirty coolant and to assist you dispose of it properly.

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

You Don’t have to Mix every Coolants with Water

Now that we understand the basic differences between engine coolant and antifreeze this concern is much an ext manageable.

Some engine coolant will certainly come premixed native the store and is prepared to be included to your vehicle as is. It does not should be included to water. If you space not sure if you have actually purchased a premixed engine coolant, inspect the instructions on the label.

To identify what kind of engine coolant your auto requires describe your car’s owner manual. Typically your vehicle will be labeled near the fill spot as well showing what color of engine coolant is recommended. They room traditionally eco-friendly or orange.

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

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

Why perform We include Antifreeze come The Water We usage To Cool our Engine?

Water is corrosive and also will at some point corrode the engine and cause rusting the the internal materials it come in contact with make them can not to perform their job.Water has a fairly low freeze point, however in most locations of the civilization winter does obtain cold sufficient to lug fresh water to a hard ice. If this to be to happen within a auto it would certainly break the engine.Coolant also keeps the water native boiling once it gets as well hot. When engine coolant boils, or any kind of other fluid for that matter it can not get any kind of hotter when in the liquid form. What this way is the it is no longer efficient at receiving warm from her engine or cooling something down.Essentially coolant protects your car’s cooling device when driving in too much weather climates. For this reason if you’re planning top top adventuring towards the poles in your automobile or driving through fatality valley you should make sure your car coolant levels are full and also have been blended with the proper coolant for your vehicle

What Happens when You add Water come Antifreeze?

The properties of water transition when developing a equipment with antifreeze. The temperature in ~ which the boils increases. This renders it far better at withstanding heat and in turn improves its capability to cool under what it comes in call with.

Water is fantastic conductor meaning it obtain energy, or heat, well. When you include antifreeze to the mix it i do not care even much better at conducting by nature of the boiling allude increasing.

Essentially the fluid solution deserve to retain an ext heat before being converted into a gas state. Layman’s terms here is that the systems containing antifreeze is far better at cooling down the hot engine parts as soon as it runs with your engine blocks.

Antifreeze is likewise a transport for number of additives that minimize the services corrosive effects. This additives may include yet are not minimal to sodium silicate (an aluminum anticorrosive) and antifoaming agents.

You want to constantly read the manufacturer’s instructions to check out how and if you must mix coolant through water.

It’s also important to keep in mind that antifreeze is an extremely dangerous come animals. That is enticing come dogs and cats because it tastes sweet to them. Lock will try to drink that if given the chance and it is usually deadly.

Make certain You Dispose Of your Antifreeze Properly

Be mindful with your used engine fluid throughout the removal procedure as that is toxic and also should not just be dumped out through the trash or under a drain.

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

Used engine coolant deserve to be properly disposed of nice easily. Many mechanics will take it off her hands for free (they make money when they sell it off to the handle companies).

You can likewise recycle the fluid at your regional disposal center or hire a private waste disposal agency to come choose it increase from you.

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

What type of Engine Coolant must I Use?

Wouldn’t it be lovely if most automobile manufacturers provided a consistent form of engine coolant? fine they don’t and also I recommend checking your car’s user manual to uncover the manufacturer’s recommended type of engine coolant. From over there you can choose a brand or generic amongst this category of coolant.

There are three typical varieties of engine coolant: lock are not natural additive technology, essential acid modern technology and ultimately hybrid organic mountain technology.


This solution a little outdated and also is less superior 보다 its rivals nowadays. As there room now more effective alternatives on the engine coolant sector you frequently only see not natural additive technology in larger vehicles.

If your vehicle uses this type of engine coolant it is vital that you remain on peak of flushing your system and replacing her coolant.

Inorganic additive technology coolant have to be adjusted every 24,000 miles or two years, whichever comes first. This is far an ext frequent than newer coolants that room on the market.


The following coolant we are going to comment on is much an ext with the times and requires far less maintenance and upkeep. It is increasingly famous in vehicles more recent than the year 2000.

Organic acid technology coolant, which is widely supplied by general Motors, only requirements to be changed every five years or 150,000 miles! the is a remarkable long size of time the you have the right to go without replacing your coolant. This conserves these automobile owners time and money associated with maintenance procedures.

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

It is derived using fully neutralized organic acids and azoles and these room the contents that make the liquid anti corrosive. This is likewise where the substance received its name.


Finally we have actually Hybrid organic Acid technology which is a slim variation that Organic mountain Technology. Both of this coolants have essentially comparable replacement cycles

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

Eventually the chemicals in antifreeze do malfunction and come to be less reliable at keeping your car’s temperatures moderate. As soon as this wake up your car is at greater risk the engine overheating which have the right to lead to costly repairs.

Its finest to it is in proactive right here and readjust this antifreeze combination every 30,000 miles or therefore for most vehicles. Her car’s user hand-operated should do a reference on this mileage specific to your auto in the same section wherein they detail what

What The color Of her Anti-Freeze Means

Until really recently the most frequently used color of antifreeze to be a neon green. This is since this is the shade that is connected with the variety of coolant called Inorganic Additive modern technology or IAT.

IAT has actually been ~ above the decline as the selection of automobile manufacturers simply due to the fact that there room now more effective coolants ~ above the market. Increasing in popularity room orange and also red coolants i m sorry are typically of the organic Acid an innovation variety that coolant.

While these types of coolants room traditionally these colors girlfriend should always verify that you space using the proper coolant because that your vehicle using her owners hands-on of her vehicle.

Nowadays coolant color doesn’t typical as lot as it used to. The purpose of companies who manufacture engine coolant dice their products is for marketing purposes and safety concerns.

Antifreeze is by nature clear. By making the a ghastly bright shade it walk a pair things. It provides the substance easy to recognize when contrasted to water.

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

Antifreeze carriers can add whatever color dye castle would choose to their product. Hence I encourage my readers no to use shade alone as a way to identify the selection of antifreeze the is an excellent for your car.

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

It relies on what you take into consideration to be “battery water”.

Some individuals refer come battery water once talking around the fluid within vehicle batteries dubbed electrolyte. Electrolyte is a mixture of sulfuric acid and also pure water. It should never be added to the coolant system in your car. Please do not drain your battery right into your cooling system.

To others the ax battery water refers to the water that you include to your battery. This water is just distilled water.

Putting distilled water in her radiator is a generally accepted practice but I encourage people to opt for soft water over distilled water. My reasoning here is that soft water has actually a full collection of valence electrons whereas distilled water go not.

Essentially that means that soft water will not piece the steel in your engine block in the same means that distilled water will. If you are puzzled by this ns cover more on the science behind distilled water and also soft water in the direction of the start of this article.

Opt because that soft water over distilled water. Everything you execute though, don’t drainpipe battery liquid into her car. Ns willing to gambling it will certainly go poorly for you and your car.

How to safely and effectively drain and flush your cooling system

Most of my readers are interested in engine coolant due to the fact that 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 room replacing the liquid properly and also especially the you dispose of your old coolant in a responsible fashion.

Coolant Leaks can Be one Expensive worry – get A car Service Contract & protect Yourself From fix Bills


Car repairs have the right to be absurdly expensive, and also you deserve to expect those unforeseen repairs before too long no issue what vehicle you drive.

If there’s an concern with her engine coolant, it can cause significant damage to your engine. For many vehicles, a new engine can expense up to $5,000.

If that seems absurd come you, luckily you aren’t alone.
