Yes, friend can. And in that situation, girlfriend should. Water in your automobile radiator beats nothing, hands-down.
Water matches Coolant
A long time ago — a really long time ago — dare ran through water in your radiators most of the time and people included antifreeze when it gained cold. Back then, cars were simpler, engines ran cooler and, uneven something was wrong, the boiling suggest of water (212 levels Fahrenheit in ~ sea level) to be high enough that it operated just fine.
Modern engines run at higher temperatures. Running just water in your car’s radiator will guarantee overheating and damage, including to her cylinder heads and also engine block. And also most madness water has minerals that will certainly leave deposits within the radiator, leading to corrosion, shortening that life and further diminishing its ability to cool.
Coolant provides a protective coating for her radiator come inhibit corrosion. A 50/50 mix the coolant and water additionally lowers the freeze temperature and also raises the boiling allude of the water in her car’s radiator. Instead of freezing and also cracking your engine block at 32 degrees Fahrenheit, a half-water, half-coolant mix has actually a freezing allude of an adverse 34 degrees. The boiling point takes a healthy jump native 212 degrees to 265, together well.
So, if you find yourself in the case we began with — questioning yourself if you deserve to put water in my automobile radiator — make certain it’s for a brief distance only — simply far sufficient to buy and add coolant. Then, see a mechanic to find out why you were low in the first place, repair any type of leaks and also flush the system, and add a new 50/50 mix of water and also coolant with a funnel.
Why no Use simply Coolant?
That’s too much of a an excellent thing. Remember, water has actually natural cooling properties. It’s why friend drink it. The coolant’s job, beyond inhibiting corrosion, is stretching those properties to make freezing or boiling happen external the normal selection of temperatures her engine experiences. Coolant by itself would freeze in ~ 8 levels Fahrenheit. Wouldn’t you rather be protected to an unfavorable 34?
