Step 2: Clean

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.

Change it every two years or so.
