The use of anti-freeze had been decreasing recently, either as a result of modifications in or reduced extreme cold temperatures that usually occur during . Despite that, there are still places round the globe that it must be necessary to use anti-freeze during. The reason why such place must need it, is to avoid a total knock down of their .
Beside the , other still need anti-freeze to avoid similar problems it could give to .
Even though a is kept in a heated garage in , its may freeze up when the is used. The first sign of a frozen will be the squeal made by the trying to turn the frozen water pump. If the is driven straight from its heated garage when the air is below freezing point, the thermostat will stay shut and the water in the will not circulate. In a short time, soft, mushy ice will form in the tubes, and they will become blocked.
Once this happens, even though the thermostat opens, no additional cooling is available and the overheats. This is the reason why so many without anti-freeze are seen boiling on a freezing morning.
A good quality anti-freeze will prevent the from freezing. The higher the concentration of anti-freeze, the greater the protection. In Britain a 33% anti-freeze/water mixture gives adequate protection. In addition, it contains inhibitors which discourage rusting or , particularly of aluminum components, and so gives benefits all year round. Over a period (some anti-freezes have a claimed life of 2 or 3 years), the inhibitors lose their effect, and after the recommended lifetime the should be drained and the anti-freeze renewed. Note that, topping the anti-freeze with water alone can weaken the mixture in the anti-freeze.
