Do new cars need antifreeze in winter?

[VanHolden]

New cars require antifreeze in winter. The original antifreeze is a high-concentration ethylene glycol-based type, whose freezing point varies with the ethylene glycol concentration in the aqueous solution. The procedure for adding coolant is as follows: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the antifreeze; 2. Insert a rubber tube into the radiator filler neck, then turn on the tap to flush the engine cooling system; 3. After draining all water from the cooling system, close the radiator drain valve; 4. Unscrew the reservoir cap and add antifreeze until the liquid level reaches the MAX mark; 5. Tighten the reservoir cap; 6. Start the engine and let it idle for 2-3 minutes, then unscrew the radiator cap to allow the cooling system to expel air. The antifreeze level will drop - replenish it again until reaching the MAX mark.
