How to Replace Coolant for JAC Refine S3?

[DiJayden]

Replacing the coolant involves the following steps: 1. Open the engine hood, unscrew the radiator cap, and open the radiator drain valve to drain the coolant. 2. Connect a tap water hose, insert it into the radiator filler port, turn on the faucet, and let tap water continuously flow through the engine cooling system. Keep the engine idling until clean water flows out from the radiator. 3. Once clean water appears, turn off the faucet, wait for the cooling system water to drain completely, and then close the radiator drain valve. 4. Add coolant to the radiator filler port until the radiator is full. Then unscrew the reservoir cap and add coolant up to the "Max" mark. 5. Replace and tighten the radiator cap and reservoir cap. 6. Start the engine and let it idle for 2-3 minutes, then unscrew the radiator cap. At this point, as some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "Max" mark.
