Keeping your car radiator cool in an emergency
The most common question we get is, “Can I use water instead of coolant for my radiator? ”
When your engine is overheating or the coolant overflow reservoir is empty or very low, you can place water in your car radiator to cool it.
When driving only a short distance, you should take this into consideration. It is important to flush the radiator and fill it with the correct coolant mix when you arrive.
In addition to offering excellent engine coolant products, Natrad also offers expert advice. Make sure your vehicle has the right coolant by visiting Natrad.
How To Check For A Problem With Your Car’s Cooling System
Your car’s dashboard will light up a thermometer symbol when the cooling system and engine are malfunctioning. An overheated engine will display this symbol. Overheating might be caused by a broken component, or you may have a coolant leak. It’s hard to know what the cause is just now.
What Do You Do If Your Car’s Radiator Stops Working While You’re Driving?
It is important that you pull over immediately if you notice your vehicle’s engine temperature rising.
When the engine is hot, don’t open the coolant pressure cap, as steam or hot coolant may cause injury. The engine block should be allowed to cool, and the coolant overflow reservoir should be checked. It may be necessary to decide whether to fill it if it is really low or empty:
- You can contact your roadside assistance provider for help
- We may be able to help you if you know the location of your nearest Natrad store
The radiator fluid in your car needs to be topped up before you drive to us.
Water can be used to top off your radiator in an emergency, however, you must have proper radiator coolant with you.
It is not a good idea to replace coolant with water, since it may have long-term negative effects on the health of your vehicle. However, it is better than nothing at all.
How long can I drive my car without a working radiator?
If you don’t have a radiator, your car will run for about five to fifteen minutes before overheating. You can also influence how long you can drive by how hard you push your engine, how fast your vehicle is going, how strong the wind is, and how cold it is.
Overheating your engine is not a good idea if you are going to be driving. When the engine is overheated, significant damage can occur.
How To Fill Your Car Radiator With Water
Filling your radiator’s coolant level with water safely is as simple as following these steps.
- If you want to make sure the vehicle is in Park and the parking brake is engaged, make sure the engine is off and cool.
- The coolant reservoir or radiator cap should be removed after the engine has cooled down. A hot cap can sputter coolant and cause burns if it is attempted to be removed when hot.
- Using a towel or thick cloth, loosen the cap carefully, taking care not to be scalded by pressurized gas or fluid. Remove the cap completely after allowing the pressure to release.
- An indicator will indicate ‘Full’ on the coolant reservoir. It needs to be filled up to that line with water. Water should be filled to the brim of the radiator when added directly.
- Make sure the cap is replaced, tightened to a click, and shut the bonnet of the car.
How much water does a car radiator hold?
If your radiator has been drained completely due to a leak, you should fill it up as much as possible before taking it to a mechanic.
In your owner’s manual, you will find information about how much coolant your radiator can hold. This will provide you with an exact figure. This is the amount of water you will need. The liquid within your radiator can also be filled until it reaches the “Full” line.
What Type Of Water Is Best?
It is recommended that you top off your radiator with high-quality water if you do not have coolant handy. In an ideal world, distilled water would be used. In addition to bottled water, tap water can be used.
You should be aware that tap water and bore water contain minerals which can cause deposits throughout your cooling system, contributing to corrosion which contributes to a shorter lifespan for the radiator and other cooling system components.
If you’ve put water in your radiator, tell our mechanics what kind of water you used when you reach your nearest Natrad store. Once it has been flushed out, the radiator will be cleaned, and coolant will be refilled.
When Can I Add Coolant To The Radiator Again?
Find out why the coolant in your radiator is low by having a technician examine it. Any leaks in the cooling system will be repaired, damaged cooling system components (like the water pump) will be replaced, and before the coolant is replaced, the system will be flushed.
Before top-ups of coolant are performed, it is necessary to flush out the radiators. If you fail to flush your radiator properly, it may fail. When your technician has repaired your cooling system, make sure the radiator is completely flushed.
Your vehicle manufacturer should specify which coolant solution to use after flushing the radiator thoroughly.
You should get your car to a radiator technician if you are forced to drive it with water as the coolant because the coolant is losing volume.
In the event that the radiator and heater are damaged extensively, it is best to repair them as soon as possible.
In addition to diagnosing and repairing radiator problems, Natrad technicians can also flush your radiator. With our large inventory of high-quality coolants, we will ensure your vehicle runs smoothly by filling it with the correct coolant.
If you need radiator repairs, coolant topping up or a cooling system flush, visit Natrad.
Water’s Pros and Cons
Understanding radiator fluid is the first step to understanding what plain water does to your radiator.
Originally, radiator fluid (also called coolant or antifreeze) was created by mixing distilled water with either ethylene glycol or propylene glycol (plus corrosion inhibitors and other additives according to the brand).
A number of important functions are performed by these ingredients in coolants:
- Rust prevention
- Enhancing the boiling point of water
- The freezing point of water is lowered
In order to be effective, coolants must possess these qualities. If you add water to a radiator, you dilute the remaining coolant, reducing its corrosion inhibition and temperature resistance.
When your car’s radiator contains mostly or entirely water, you can still drive it, but for only a short time. Long-term damage can occur to your engine if it is operated with just water.
