While you can drive the car for a short time using water in place of the coolant, it won't effectively protect your engine. This means its essential to get the problem that caused a low coolant level fixed as soon as possible, and the radiator filled with a 50/50 ratio of coolant to water.
What happens if you put 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 safe to put water in your coolant tank?
In the vast majority of cases, it is completely safe to refill your vehicle's cooling system with water, in the event of an emergency. However, before doing so, it is important to understand that water offers no freeze protection, and also boils at lower temperatures than antifreeze.
Is it better to use coolant or water?
While water does help to keep your engine cool, it does not work nearly as well as coolant does. First of all, water boils faster and at a lower temperature than coolant. If it is winter, then you risk having your engine block crack if you run your engine with only plain water.
What happens if you add water to 50/50 coolant?
You aren't really protecting anything by doing it. 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.
How long can you run engine without 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.
What happens if you put water instead of coolant?

Can you put straight water in your radiator?
Answer provided by It's okay to use straight water in your radiator in a pinch, like if your engine is overheating and you're out of coolant. But it's not recommended you drive any extended distance with straight water in your radiator, as this can cause severe damage to your engine.
What kind of coolant does my BMW need?
Your BMW, Porsche, Mercedes Benz, Audi or Volkswagen uses an HOAT coolant. HOAT coolants are derived from OAT coolants with the addition of silicate to protect aluminum surfaces.
How long can you drive with water in radiator?
You may be able to run without coolant for up to five minutes depending on the engine, the model of your car, and how hard you try to work the engine.
Can I mix coolant with tap water?
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. And over a long period of time they can lead to over-heating.
Is engine coolant just water?
Stop your car overheating Engine coolant is a mixture of water and anti-freeze that helps to stop your engine overheating. Most modern cars have a sealed cooling system so they shouldn't need topping up.
Can I drive my BMW with low coolant?
To ensure the engine stays at an optimal operating temperature, your car relies on a fluid called antifreeze, or engine coolant. Driving with low coolant could let your engine get too hot, which usually spells trouble for your engine, your vehicle, and your journey!

Can using water instead of coolant cause overheating?
Can I use regular water instead of engine coolant in my car? No. Regular water or even distilled water will cause the engine to overheat. You might end up with a cracked engine block due to thermal expansion.
How long can you run engine without coolant?

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.
Can you use water instead of coolant in the winter?
Technically speaking yes you can use plain water in your cooling system but it isn't recommended as a long term solution and certainly not in extreme weather conditions. The problem with using water in your cooling system is that water freezes at 0°C.
Does BMW require a 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.
Why is my BMW coolant low?
Reasons Why Your Coolant Might Be Low leak in radiator. leak in radiator hoses. leak in water pump. damaged or broken radiator seal.
Does BMW coolant need to be mixed with water?
They need to be combined to create the good coolant. You can purchase ready-made mixtures of coolant that already have water added, or you can purchase full-strength antifreeze which needs to be diluted with distilled water before being added to the engine system.
Can I put straight water in my radiator?

When the cooling system reaches a low pressure, the car might perceive this as low coolant. In this case, the sensor will likely need to be replaced. Coolant leaks can occur due to a number of reasons, including a broken radiator seal or a compromised radiator.
Can you use regular coolant in a BMW?
Therefore, the coolants designed explicitly for such vehicles help prevent rusting or cause other harm like damage to the cylinder gasket, water pump, and radiator. In worst situations, prolonged usage of a regular coolant may compel you to install a new engine in your BMW car.

Can you mix antifreeze and water in the radiator?
Water is often mixed with the coolant in a 50:50 ratio; you can also add antifreeze if you live in areas with extremely cold temperatures. The reason why water is not used alone in the radiator is that it has a low boiling point compared to the coolant.
