Make sure your bike doesn’t catch a cold this winter, by ensuring that it has the correct level and concentration of engine coolant. That’s the advice from lubricant specialists Q8Oils. According to the AA a 50:50 mix of antifreeze and water in the cooling system is needed in winter. This gives maximum protection down to -34° centigrade and without it severe engine damage costing hundreds of pounds can occur. While it may sound odd to raise the subject of coolant in winter, modern motorcycle coolants are designed for year-round use. They have a higher boiling point than water, for summer cooling, and a lower freezing point for winter protection. If the coolant has been diluted, perhaps by topping up with water over the summer, it may freeze during a cold spell of weather. Just like the effect of freezing on the pipes in your house, this has the potential to cause damage by bursting the radiator and hoses on your motorcycle.
