Is it OK to put only water in your radiator?

Running just water in your car’s radiator will guarantee overheating and damage, including to your cylinder heads and engine block. And most tap water contains minerals that will leave deposits inside the radiator, causing corrosion, shortening its life and further diminishing its ability to cool.

Is it better to put water or coolant in radiator?

It’s much better for the engine to use water than to drive with low coolant, but you should replace the water with the correct coolant for your vehicle as soon as possible. When you add water to the radiator, you dilute any coolant that may still be in the radiator.

Can you use water instead of coolant in the summer?

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. Even if it is the height of summer, failing to put antifreeze into your coolant system can be detrimental to the health of your vehicle.

Can I pour water into my radiator instead of coolant?

The short answer is that it’s a bad idea to pour pure water into your radiator, no matter what your climate conditions are. A proper coolant mixture is essential to the proper operation of your engine’s cooling system and to its long life.

What should I do if my car radiator is leaking water?

Check the radiator for water levels. If you cannot see any liquid, it could mean that your radiator system is leaking. The rule is to use a 50/50 mix of coolant and water. The coolant has a higher boiling point than normal tap water. It helps to keep your engine cool.

Can you use water as a coolant in an emergency?

Yes, you could use water as a coolant in an emergency. However, doing so is not recommended since water won’t work well beyond its freezing and boiling points. This could also cause expensive engine damage. So, use it only in unavoidable situations.

Is distilled water better for your car than coolant?

Distilled water, on the other hand, is free from any residue. This is why it’s used in combination with antifreeze. Coolant not only changes the freezing and boiling point, but it also creates a protective layer on metal parts. Your radiator and engine will last much longer using the proper antifreeze.
