Can you put hose water in a radiator?
Hereof, is it OK to put tap water in a radiator?
Yes, there is. Tap water and even purified water have minerals in them. These minerals separate from the water in the radiator and engine under the extreme heat and pressure during engine operation. You want to use distilled water in your radiator, or just buy premixed 50/50 antifreeze and don't worry about it.
Keeping this in view, what kind of water do you put in a radiator?
The best water you can put in your radiator is either totally pure deionized water, or truly softened water. Both of these waters are devoid of calcium and magnesium. These are the hardness elements and this is what ruins radiators.
To add liquid to your radiator, follow these steps:
- Open the radiator cap.
- Look into the radiator fill hole to see how high the liquid level is inside.
- Add water and coolant, or pre-diluted coolant, as necessary.
- Replace the cap by screwing it on clockwise.
