How to Tighten the Antifreeze Cap?

[LeBeckett]

The method to tighten the antifreeze cap is: turn the antifreeze cap until you hear a click. The functions of antifreeze are: 1. Provide freeze protection for the engine against low-temperature environments; 2. Offer efficient heat dissipation; 3. Prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when parked in cold winter. The steps to replace antifreeze are: 1. Unscrew the radiator cap to drain the antifreeze; 2. Run the engine at idle speed and inject clean water until the radiator discharges clear water; 3. Close the water valve after all clean water has drained; 4. Fill with new antifreeze until the liquid level is between the max and min marks; 5. Close the cap and let the engine idle for two to three minutes.
