How often should the coolant be replaced in a Focus?
1 Answers
The recommended interval for replacing the coolant in a Ford Focus is every 2 years or 40,000 kilometers. Coolant, short for antifreeze coolant, is designed to prevent freezing. It protects against the expansion and cracking of the radiator and engine block due to freezing during cold weather. Coolant is not just for winter use; it should be used year-round. Failing to replace the coolant for an extended period can lead to a decline in its quality, reducing its anti-corrosion properties and potentially damaging the radiator and pipes. Coolant is primarily used in liquid-cooled engine cooling systems and offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. It is advisable to use the same brand of coolant. Different brands may use different metal corrosion inhibitors, making them incompatible. Most coolants have a shelf life of two years (some products may last longer), so ensure the product is within its validity period when adding it. When replacing the coolant, drain the old fluid completely, clean the cooling system thoroughly, and then add the new coolant. Traditional inorganic coolants should not be diluted with water, as this can cause sedimentation and severely impair their functionality. Organic coolants can be diluted with water, but excessive dilution should be avoided.
