Not Changing Coolant for Ten Years

[LeMicah]

Follow the coolant replacement interval specified in the vehicle's manual, typically every two years, though some may indicate 4-5 years or longer. Adhere to the owner's manual instructions. Below are extended guidelines on coolant: 1. Regularly check the coolant level; if below the minimum mark, replenish promptly. 2. Before each winter, measure the coolant's freezing point to ensure it remains 15°C to 20°C below the local minimum temperature. 3. For vehicles without specified replacement intervals, assess the need for replacement by observing the coolant's condition—cloudiness, sediment, or excessively high freezing point. 4. Coolant colors may vary across different vehicle models; avoid mixing them.
