What is the Difference Between Car Antifreeze and Windshield Washer Fluid?

[VanErin]

Car antifreeze and windshield washer fluid differ in their purposes: antifreeze is used for engine corrosion prevention, rust protection, and scale inhibition; windshield washer fluid is used for cleaning the windshield. The steps for replacing antifreeze are: 1. Open the vehicle's engine hood and locate the antifreeze reservoir; 2. Open the antifreeze drain plug under the radiator to drain the antifreeze; 3. Add new antifreeze and tighten the cap. Precautions for using coolant: 1. Do not mix different types of coolant; 2. Avoid using low-quality coolant; 3. Do not directly add concentrated coolant to prevent deterioration and excessive viscosity at low temperatures. The functions of antifreeze are: 1. Providing anti-corrosion protection for the engine's cooling system; 2. Preventing scale formation to avoid reducing the radiator's heat dissipation efficiency; 3. Ensuring the engine operates normally at low temperatures.
