It is widely accepted that you should replace your antifreeze every two years but you can buy a hydrometer to check it to be sure. After prolonged use, antifreeze will beak down and become very corrosive. It can lose its rust preventative properties and the cooling system can fail.
Your anti-freeze is a Dex-cool anti-freeze. It is not compatiable with the green kind. It is a long life coolant which can last up to 100,000 miles. If you have to top off, do not add water as this coolant comes pre-mixed.
Yes it can freeze.
Yes, anti-freeze can kill you if you drink it.
GM Dexcool nothing else. Your anti-freeze is a Dex-cool anti-freeze. It is not compatiable with the green kind. It is a long life coolant which can last up to 100,000 miles. If you have to top off, do not add water as this coolant comes pre-mixed.
If you freeze it, it will last for years.
50% anti-freeze, 50% water is normal, this can be elevated to 70% anti-freeze, 30% water. It is not recommended to have a higher anti-freeze ratio than this.
This happened to me last winter. It ended up being that I was low on anti-freeze. I filled up the reservoir with the correct mixture of anti-freeze and distilled water and voila I had heat!
The color of the antifreeze does not have anything to do with the type of anti-freeze. Anti-freeze manufacturers can make their anti-freeze any color they choose. You can use any SAE certified anti-freeze in your 1997 Toyota Corolla.
It's due to the car over heating and it's usually because of cheap anti freeze or too much water in the mixture. (Probably a clogged radiator or a bad thermostat, too much water or "cheap anti-freeze" has nothing to do with it. They don't make "cheap" anti freeze. Anti-freeze is just that... anti-freeze!)
Well, it should last a month.
All Caravan and Grand Caravans from 95 -2003 will run happily on regular green anti-freeze. I have had 4 of these vehicles and never a problem with anti-freeze.
if your anti freeze is green. always stay with green anti freeze. if it is orange. always stay with orange anti freeze no ifs,ands,or buts about it.
