How to Replace Coolant More Thoroughly?
1 Answers
Draining the coolant from the drain port at the bottom ensures a more thorough replacement. Here are the detailed steps: 1. Locate the coolant reservoir. 2. Some old coolant may remain in the reservoir; drain all of it. 3. Find the connection point—a tube can be seen behind the condenser. 4. Unscrew the clamp on the tube, then pull the tube out directly, allowing the old coolant in the reservoir to drain. 5. Refill with new coolant until the level stabilizes at the marked line. Coolant Usage Notes: 1. The replacement interval for coolant is detailed in each vehicle’s maintenance manual. Generally, coolant should be replaced every two years. Users in southern regions can extend the replacement cycle slightly compared to those in northern regions, where it is recommended to replace the coolant annually. This is because northern areas experience prolonged snow and rain for several months, demanding higher-quality coolant. 2. Coolant consists of a base fluid and soft water. The base fluid can vary, including types like tetra-alcohol, ethanol, ethylene glycol, or glycerin. Soft water refers to water with little or no calcium or magnesium ions, such as distilled water, uncontaminated rainwater, or snowmelt. In winter, the proportion of base fluid in the coolant should be increased. However, it should not exceed 60%, as an excessive base fluid concentration can reduce the engine’s cooling efficiency.
