How often and how to replace Volkswagen's new polo antifreeze?

Volkswagen's new Polo antifreeze is usually changed once every two years, but after the high temperature in summer, the antifreeze is likely to have been reduced and needs to be added. Replacement steps of new Polo antifreeze: Step 1: Check. 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 after the 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 a role.

The second step: cleaning. Drain the old antifreeze, clean the liquid channel with clear water, add clear water to the antifreeze replenishment tank, then inject clear water into the tank to make the clear water continuously flow through the engine cooling system, then start idling for 3 to 5 minutes to make the water circulate, and the water flowing out of the water tank is a little pink, and continue to inject clear water until the water flowing out is clean. Don't forget to remove the heating water pipe and clean the water in the heating water tank. Step 3: Replace with new antifreeze. 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), and then add a bucket of antifreeze to the antifreeze tank until the antifreeze tank is almost full, and ignite the car for about 10 minutes. At this point, the liquid level of the cooling system drops due to the exclusion of some air, and then antifreeze is added as long as the liquid quantity is at the highest (MAX

Precautions: open the lid of the water tank and pay attention to the cooling state of the water tank; Observe whether there are impurities in antifreeze; The final liquid level should be kept between "highest" and "lowest"; When finished, tighten the water tank cover.
