Distilled water has no added minerals (the type you’d find in well water or city tap water), which prevents mineral contamination inside of your cooling system. It’s been steam distilled to remove all mineral impurities, making it safe for use in your BMW’s engine and cooling system.

Can I put distilled water in coolant reservoir?
As it chemically removes electrons from the metals of cooling system components, distilled water eventually does extreme damage that could lead to cooling system failure.
What kind of water do I mix with BMW coolant?
Coolant is mixed with distilled water for the best protection against boiling, freezing, corrosion, and lubrication. A 1:1 mix of antifreeze and distilled water will give the best protection in street cars.
Should BMW coolant be mixed with water?
Keep in mind, you never want to pour antifreeze or water by themselves into your engine system. They need to be combined to create the good coolant.
How do I mix BMW coolant with distilled water?
Last edited by novasol; 12-26-2011 at 06:04 PM. I just keep an old coolant jug (same jug like the coolant came in) for mixing 50/50. If you’re completely draining the radiator, pour half the coolant in, pour the other half into another container, fill the coolant jug with 1/2 distilled water & dump into the radiator.
Which is better coolant or distilled water?
By itself, distilled water, is much better at heat transfer compared to antifreeze/coolants. However, water, by itself, causes the metal parts in the cooling system to corrode. Antifreeze/coolants also cause corrosion, but modern versions of the product have been infused with rust inhibitors.
Can you top up coolant with just water?
This is a frequently asked question, yes you can top up with just water, but you should only do this in an emergency to enable you to get to a garage. Engine coolant contains antifreeze, so diluting with water will lower the boiling point and the coolant will stop to work efficiently.
What happens if you use water instead of coolant?
If you were to just use water rather than the coolant mixture, high temperatures inside the motor would easily boil that water and cause it to evaporate, meaning you’d quickly have no coolant at all and the engine would easily overheat.
Is it OK to mix water with coolant?
No! You should never mix coolant fluid with regular tap water. Tap water contains minerals that can form deposits inside the radiator and cooling system passages of your engine. Use only pure, distilled water.
Do I need to use distilled water for coolant?
The question comes up: Do I use regular tap water when mixing my coolant and water together? No, you should use distilled water or better yet, de-ionized water. The reason for this is that tap water has minerals that can deform deposits inside the radiator and the cooling system passages of your engine.
Does a BMW need special coolant?
BMWs have specific coolant requirements (nitrite and phosphate free) to prevent build-up and corrosion of aluminum components, so not just any off-the-shelf antifreeze will do.
Is BMW antifreeze already mixed?
For that small amount I would just add some distilled water. BMW coolant does not come pre-mixed.
Does 50 50 coolant need water?
You’re just putting a weak form of antifreeze into your cooling system, which will drop the freeze point a few degrees, but won’t stop it from freezing. 50/50 coolant is ready to use. Don’t add water to it.
Why does BMW use blue coolant?
We recommend using BMW’s “Blue” coolant in your car because it is silicate & phosphate free, and has a much longer lifespan inside of your car’s cooling system.
What color is BMW antifreeze?
Genuine BMW green HT-12 antifreeze for optimal cooling system performance. Compatible with all BMW models.
Why should you mix a 50/50 blend of water and antifreeze?
A 50/50 mixture of antifreeze and water is the standard recommendation for most applications because it provides the best all-round cooling protection and performance for most applications. Premixed antifreeze is 50/50 and takes the guesswork out of correctly mixing antifreeze and water.
How much water do you mix with coolant?
Mixtures with a ratio of 50:50 work almost in every climate. In climates where temperatures drop below 0℃ for a longer period, mixtures closer to 60% antifreeze and 40% water are better suited to keep coolant from freezing.
Is deionized water OK for coolant?
Deionised water is used in cooling systems because of its low conductivity. This means it can stop certain devices from overheating and be able to maintain a certain temperature level. Also ideal for other medical devices.
Why is distilled water better in a radiator?
If you use only tap water inside the radiator, your engine and radiator can start building up deposits of minerals from the water that can damage it. Distilled water is safer but it can also rust and corrode from the water, mineral or tap. This will eventually lead to serious engine and radiator damage.
What is the best coolant to be used for radiator?
- Zerex Original Green.
- Zerex Dex-Cool.
- Zerex G-05.
- Zerex G-48.
- Zerex Asian Red Vehicle.
- Zerex G-40.
Can you put tap water in a car radiator?
What does matter is that the water is distilled or bottled, since tap water often contains minerals or suspended particles that can damage engine components and clog up the radiator pipes over time. Pour in equal amounts of water and antifreeze using a funnel to avoid spillages.
How do you top up BMW coolant?
How long should I wait to start my car after adding coolant?
Once the hood is open, there’s a risk of being sprayed with hot water or steam. “Your personal safety is most important,” he says. “Waiting for at least 15 minutes allows the hood, engine and leaking coolant to cool.”
How long can you drive with low coolant?
If your car has a low coolant you can drive for some time. It really relies on the level of coolant. If it is low but it is above the minimum, you can drive your car for a few days. But if it is below the minimum, please do not even try to run your engine.
How long can you drive with water instead coolant?
However, if you absolutely must start your car without coolant, it can probably run for about a minute without too much risk of damage. You may be able to get away with as much as 5 minutes of running without coolant, depending on the engine, car model, and how hard you’re asking the engine to work.
