If in doubt, I would get the car transported to the mechanic - even if you pay retail for the recovery it's likely to be cheaper than a blown engine, unless the engine is fairly terminal already. for some good advice (which broadly speaking boils down to don't do it!). First rule is simple -- if the temperature is above the normal (usually half-way, or in some cars just a hair above half-way on the gauge), pull over and stop the engine. The car must be taken to a mechanic. Can You Put Water In Coolant Tank? A radiator tester can be used to test the temperatures inside the radiator. The coolant in the car, and it is called coolant now not anti-freeze, is year round. Posted on: Apr 26 2018 By: Hy-per Web Crew View all 2 responses; We get this question all the time when talking to customers on our tech line: What is the best type of water to use in my cooling system?”In this post, we would like to address this topic, as the plethora of misinformation … This is essential in a car engine as the purpose of the radiator is to regulate the temperature of the engine as it works. Excessive engine heat can cause damage to some of the sensitive engine parts. Only you can assess your position and condition relative to the damage that your car might sustain. It will pull the water in and mix it with your coolant. The radiator uses a mixture of coolant, water and sometimes antifreeze to keep the engine cool. The coolant has the important task of preventing corrosion in the engine block, but you should not use it excessively. The only time it would be a problem is if you had just water and no coolant/antifreeze. After this I drove the car trying to maintain under 3000 rpm and made it to the mechanic's shop like that. It ensures that the maximum amount of heat is removed from the coolant. Yes you can put water in your coolant for your vehicle only in non-winter weather states. A few years ago, most cars only ran with water in the radiator. With all its moving parts, an engine generates a lot of friction and heat and the coolant passes through channels in the engine to withdraw that heat. I once had an accident that punched a hole in the radiator, a can of bars leak plugged the hole and I drove 150 miles home without incident - your success might vary! When I inspected the vehicle, I realized that the coolant overflow was empty and the radiator's coolant level was rather low (not sure exactly how low but it seems at most 75% remains). I don't think mixture will be problem for a 30 mile drive . First thing I'd try to figure out is how quickly it leaks - run it, stick your head underneath it as check if there is any visible leaking. Silly question: the overflow reservoir should not be empty, right? A mixture containing up to 70% coolant will still work, but a fifty-fifty mix is more efficient. Water in the radiator can become very hot, and it is not recommended to open the radiator cap while the engine is running. This will increase the cooling system capacity by allowing the heater core to dissipate engine heat -- obviously at the expense of cabin comfort. The first thing you would try is in essence what I did. I created this blog because I was tired of finding false information on the web while looking for repair information. There are other cases where the transmission radiator mixes with the coolant. Depending on what you drive and where you live, the coolant available at your nearest gas station may not be compatible with the coolant within your car, and mixing them may cause coagulation. The role that the coolant plays in cooling the engine should not be underestimated. If you did NOT operate the car after putting the washer fluid in the coolant overflow reservoir, simply use a turkey baster, or like tool, to suck the contaminated fluid out of the reservoir, pour some water in and then suck that water out as well until you empty the reservoir. Never had much luck with this, or any other "seal" voodoo. To make a painfully long story short, I had a lot of car issues the past few days and my car was leaking coolant. Faulty radiator caps cause unwanted air to flow into the thermostat, radiator core and radiator hoses. This is done by heat transfer with the coolant. I drive a 1992 camaro. If you live in a cold country with freezing temperatures – your coolant-water can freeze if the mixture is not good enough, and it can cause serious damage to your engine. I decided not to go with pure water because I have read that a 50/50 ratio of coolant to water is desirable and figured even if it were leaking, should it be slow, I should follow best practice. If there is a major leak 30 miles may be too far, and you may cause major (very expensive) damage to your cylinder head or engine block. Engine coolant has also been formulated to keep the parts in your engine from becoming corroded. Wait if you can. as a temp fix I have a plastic bottle acting as a tank with water in it. Water only is ok for short distances. The issues began about 40 miles from home and I made the very bad decision to top off the coolant and proceed rather than turn around back home and choose a different car. Radiator caps are relatively affordable, and you should replace a damaged cap immediately. It will. Overall, I would say this situation was mild in comparison to what could happen. The radiator transfers heat from the hot coolant through a fan. It's not going to damage the engine or anything will it? Additionally, you should avoid adding cold water to a hot engine unless you have no other choice - there is a risk that it can cause a thermal shock and risk cracking the block, which would end up very expensive! Please read this question on driving without coolant! Instead of using plain water, a coolant is always recommended due to a number of reasons. Perhaps these were just the first signs of the gasket going. A coolant-water solution increases the boiling point from 212 degrees to about 265 degrees compared to when only water is used. Your radiator fluid or coolant can be with antifreeze or without. If you can't get up the hill without loading the engine to the point it overheats, there isn't much you can do about that. First of all, water boils faster and at a lower temperature than coolant. I assume there is a leak in a hose, connector, or perhaps the water pump. According to me, cold water won't make a difference, since it will be heated to 160+ in under a few minutes. When coolant and antifreeze is mixed with the water it changes the temperature at which the water will freeze or boil. Ethylene glycol is extremely poisonous. Then another mechanic told me the polar opposite that it’s the winter when you can use water instead of anti-freeze and you’ll be ok whereas summer you … You should only do this when you intend to drive a short distance, and you’ll want to ensure that when you arrive you have the radiator flushed and refilled with the correct coolant/water mixture. If you can't see it, like gushing out of a broken hose or oozing from the radiator, then all you can really do is fill it and then proceed (AC off, heat on, driving very delicately) and see how far you get before the temp breaks the normal reading. Why You Should Never Use Distilled Water in Your Cooling System. Mix the two in a 50/50 ratio by filling an empty radiator fluid bottle halfway with water and topping it up with radiator fluid. Coolant and water are incomplete without each other. Do you think I should stick with water or use a mixture? You may be able to drive with a compromised cooling system at 55mph without overheating, but at 65mph it overheats. If you do this and the temperature stays within normal range (which is often the case) pull over when you can and check the coolant level. I went to the dealership and got some coolant from them to use figuring it would most likely help at least a little to have some in there. Good point about the cold water in a hot engine. If there is, don't drive it. I started the car and let it run while looking to see if any fluid was leaking and could not see any after a minute or so. I am definitely not recommending to drive a car with a major leak, or even with a medium one. It also helps the coolant boil at a higher temp. It is always recommended to use the correct mixture of antifreeze and water. CARS.COM — If you have ever ... you may have wondered whether you really need special fluid or if you could just use plain water instead. An auto supermarket should be able to help you choose the one to suit your car. Had I been close to my home it would have not been very inconveniencing. About a year after this happened the car did blow its head gasket. The reservoir was completely empty, and the radiator had a low level of water. The main function of the transmission cooler is to remove heat from the oil. Avoid stopped traffic. This is because engine load is higher, and if you are on the highway driving a long time with a compromised cooling system, the load is higher than the cooling system can dissipate the heat. Can you use only water without any coolant in the radiator? The problems fixed but I literally have no money for coolant until Friday. Below is my advice based on a lot of experience with managing a vehicle that is overheating. Great answers here, I just wanted to post what I actually ended up doing in the hopes of it helping someone at some point, or maybe to satisfy curiosity. Hills are not your friend when driving with a compromised cooling system. I was told it gets close to the upper limit very quickly upon running the car. I fill up water in my radiator like every 3 days just to be sure that it would not overheat..I drive a nissan sentra b13 and our place is tropical so I dont think that coolant mix would be necessary since our climate would not freeze the engine. I live in Orlando so obviously it never gets cold. The engine becomes extremely hot and heat is transferred from the engine to the coolant and finally to the radiator. Radiator sealant can do the job. car is missing a coolant reservoir tank and now the car is over heating. See my edit for more details. Depending on where you live, it doesn’t seem to be that bad for the engine for several reasons: With that being said, coolant has additives in it to keep it from breaking down metals and for protecting the seal (water pump). The radiator inlet allows the coolant to flow through the pipes and the fins dissipate the heat with the help of the fan. I hope you enjoy my content! Basically, and as its name suggests, coolant works to cool down the engine. Most cars today have alloy heads, and using water will cause corrosion. Because I am assuming there will be a leak, I think that when I drive it, it will most likely loose coolant. The mixture is known for doing wonders by hampering the freezing or boiling of the coolant under severe weather conditions. It caused the engine to be flooded and as a result we had to replace it. Secondly water quickly boils due to the immense heat within an internal combustion engine and would eventually evaporate as well. Check the clamps for looseness. But there are extenuating circumstances that you might be able to find a way to reach a good ending. If temps stay normal while moving but creeps up over normal while stopped, it is probably the fan. I went to two different mechanics and one told me that you can run your car in the summer with just water, HOWEVER you can’t get away with that during the winter which apparently is when you need the anti-freeze the most. @JuannStrauss - It is interesting that you mention that. It is worthwhile to also check the auto transmission fluid, because if that is low the tranny is running hotter than normal and most radiators have a section that is your transmission fluid cooler which is mounted to the radiator putting additional heat on the cooling system. The question that may though eat up your head is “can you use water instead of coolant.” Water also contains minerals that are deposited in the engine. As others have said - the short answer is don't do it. A faulty radiator cap will cause the coolant to flow into the reservoir. The coolant is indicated by a green or yellow color. Although, I wouldn’t recommend it for long term usage, it can work in a bind. The coolant is a greenish-yellow liquid that increases the boiling point of the water. This is because the coolant is released too quickly, causing the reservoir to boil over. Over time, sludge forms inside the radiator, which prevents the coolant from moving effectively. Even then, you probably are going to be OK as hopefully there is a little antifreeze left in the existing coolant. The engines were simple and this resulted in less overheating. Tap water is full of minerals that will eventually form deposits inside your radiator, plumbing and water pump. I agree with Timo - if it is a big enough leak that you can see it clearly, then getting the car transported is much safer. The radiator plays an important role in cooling the engine of a car. It will seal up any leaks and is cheap and cheerful, at least until you can make plans to address the issue full on. Kind of banking on a small leak. now instead of smoke that used to bellow out of the en … read more Yes, you can run straight water, but your coolant boiling point will be lower AND you'll corrode the inside of your engine and destroy your water pump. In general, using water as coolant is OK for a short time or as a "get you home" alternative, but it does not have the anti-freeze and corrosion inhibiting properties of a proper coolant mix, so should not be left in the engine for any length of time… Click here to upload your image pure water is not alternative for radiator coolant, because water will be boil quicker than coolant. Keep in mind that you should circle back after the repair and drain/flush and refill the system (if it was not required for the fix) so that you have the proper proportion of anti-freeze to water. Thanks. If the coolant level is down, fill it. If the coolant is low, top it off by adding clean, drinkable water to the coolant reservoir [source: pontiac ].
