What to Do If Too Much Antifreeze Is Added?

[KateMarie]

The solutions for adding too much antifreeze are: 1. Use a syringe to extract the excess antifreeze; 2. Open the antifreeze drain plug under the radiator to release some antifreeze. The steps for adding antifreeze are: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze; 2. Insert a rubber tube into the radiator filler neck, turn on the tap to flush the engine cooling system; 3. After draining the water from the cooling system, close the radiator drain valve; 4. Unscrew the reservoir cap, add antifreeze until the liquid level reaches the MAX mark; 5. Tighten the reservoir cap; 6. Start the engine, let it idle for 2 to 3 minutes, then open the radiator cap to allow the cooling system to expel some air. The antifreeze level will drop, so top it up again to the MAX mark.
