What is the replacement interval for antifreeze?
1 Answers
The replacement interval for antifreeze is every 2 years or 40,000 kilometers, whichever comes first. The functions of antifreeze are: 1. Providing anti-corrosion protection for the engine's cooling system; 2. Preventing water from boiling when the engine temperature reaches 100 degrees Celsius; 3. Preventing scale formation to avoid reducing the radiator's cooling efficiency; 4. Ensuring the engine operates normally under low-temperature conditions. The steps for replacing antifreeze are: 1. Open the vehicle's engine hood, and the antifreeze reservoir can be seen in the upper right corner; 2. Open the antifreeze drain plug under the radiator to drain the old antifreeze; 3. Add new antifreeze, tighten the cap, and the antifreeze replacement is complete.
