As we start heading into the cold, coolant flushes are an important job you may want to consider. Coolant does a few things for you – it keeps your engine from overheating (which it can still do in the winter) and can also make sure your engine and radiator do not get damaged from cold. Remember, water freezes at 32 degrees, which we hit often in the Carolinas. When water freezes, it expands and that can crack your radiator! Coolant, on top of having a higher boiling point, also has a lower freezing point too (around 220 degrees and -30 degrees, respectively.) If you are not running coolant now but you are running water, now is a good time to switch.
That same coolant is also used to heat your cabin. There is a small radiator-like device called a heater core which coolant runs through to heat your car’s interior. If it isn’t warm when you turn on the heat, now may be a good time to check out your coolant.
Also, coolant helps prevent corrosion. Coolant is made from a mixture of chemicals and over time, they wear out. Old coolant can corrode things, and those repairs, like radiator and hose replacements, can be pricey, to say the least.
Now is the perfect time to get a coolant flush, as you can gain peace of mind heading into the holiday season… which, by the way, starts in next week!
