Can Old and New Coolants Be Mixed?
1 Answers
Old and new coolants cannot be mixed. Here are the relevant explanations: 1. Reason: Different coolants contain varying chemical components such as rust inhibitors, anti-corrosion agents, anti-foaming agents, and colorants. Mixing them can easily lead to chemical reactions, causing hazards like sedimentation and scaling. Therefore, the same brand of coolant should be used for replenishment. 2. Precautions: Be cautious when selecting and adding coolant. Choose a coolant with the appropriate ratio based on specific conditions. Then, add the selected coolant to the radiator until the liquid level reaches the specified position.
