How to Replace the Antifreeze in a Sylphy?
1 Answers
The method for replacing the antifreeze in a Sylphy is as follows: Open the radiator cap, drain the old coolant, refill with new coolant, and install the radiator cap. In some cold regions, you can warm up the car for about 5 minutes before replacing the antifreeze, but be sure to turn off the engine and wait for it to cool down before replacement to avoid burns from hot coolant or steam. The specific steps are as follows: 1. Open the radiator cap: Remove the engine undercover, open the radiator drain plug at the bottom of the radiator, then remove the radiator cap. Before unscrewing the radiator cap, turn it slowly to release accumulated pressure, then fully unscrew it. 2. Drain the old coolant: Locate and open the coolant drain screw, usually located at the rear of the engine. For faster and more thorough drainage, you can add distilled water from the coolant filler port for cleaning, and use an air gun to blow out excess coolant. Note that the air pressure should not be too high to avoid damaging internal components. 3. Refill with new coolant: After tightening the drain screw, add new coolant from the filler port, generally not exceeding the "MAX" mark (approximately 6.6L). 4. Install the radiator cap: Warm up the engine for about 10 minutes at an idle speed of 3000 RPM. If the fan starts running, it indicates the coolant has reached normal temperature. Then, tighten the filler cap and install the radiator cap.
