How to Add Coolant to a Car Radiator?
1 Answers
Method for adding coolant to a car radiator: 1. Open the radiator's drain valve to release all the antifreeze inside. Insert a tube into the radiator to flush it with water. While flushing, fully release the accelerator pedal to keep the engine idling until clear water comes out of the radiator. 2. Close the drain outlet and start adding antifreeze to the radiator until it is full, not exceeding the marked level, then tighten the cap. 3. Start the engine, open the radiator cap, and let the engine idle for two to three minutes to expel some air from the radiator. If the antifreeze level starts to drop, continue adding antifreeze, then replace the cap.
