How does KIA k2 change antifreeze?

KIA k2 replacement antifreeze method: Replacing antifreeze is relatively simple. Drain the raw water tank and fresh water, then tighten the drain screw, open the water tank cover, and add antifreeze until it is full. Method of adding antifreeze (antifreeze coolant): After the car cools, open the engine compartment and check whether the coolant is sufficient. The side of the coolant pot has an upper limit scale and a lower limit scale. When the liquid level is lower than the lower limit when the vehicle is cold, the addition amount shall be subject to the scale on the pot side, as long as it is between the maximum (max) and the minimum (min). Replacement steps of antifreeze: 1. First, do a comprehensive inspection to see if there are cracks and leaks in the pipeline, with the focus on the five-way pipe (named because there are five interfaces connecting all parts). Antifreeze must flow through the five-way pipe and then be distributed to different parts of the car in order to play its role. 2. Drain the old antifreeze, clean the liquid passage with clear water, add the clear water to the antifreeze replenishment tank, then inject the clear water into the tank to make the clear water continuously flow through the engine cooling system, and then idle for 3 to 5 minutes to make the water circulate. The water from the water tank is a little pink at first. Continue to inject fresh water until the water is clean. Don't forget to remove the heating water pipe and clean the water in the heating water tank. 3. In order to make antifreeze flow into the water tank quickly, after draining for about 1 hour, add new antifreeze from the water pipe of the water tank (radiator), then add a bucket of antifreeze to the antifreeze tank, and ignite the car for about 10 minute until the antifreeze tank is almost full. At this time, the liquid level of the cooling system drops due to the exclusion of some air. Million car purchase subsidy
