Clean the sealing ring position thoroughly. Replace with a new sealing rubber ring. Cut a 6 cm long nylon rod, shaped as shown, with a small end diameter of 20 mm and length of 4 cm, followed by a step with a diameter of 35 mm. Insert it into the hole where the sealing rubber ring is located. This hole has a diameter of 20 mm. After tightly fitting it into the drainage column hole, it can be pressed into its original position. The pressure from the spring at the top of the drainage column should be slightly higher.
Installing a freeze plug is actually quite simple, but the key is to operate carefully. Last time I helped a friend with his car, we had to deal with it because the engine was leaking water. First, let the car cool down—safety first, don't burn your hands. Then clean the hole thoroughly, lightly sand off any rust with sandpaper, and make sure there are no residues left, otherwise the seal won't hold. Find a freeze plug of the right size—usually available in metal or rubber; I used a rubber one because it's more leak-proof. Apply some silicone sealant around the edge of the plug, then gently tap it in with a rubber mallet—don't use too much force, or it might deform and make things worse. After tapping it into place, wait a few minutes for the sealant to cure. Finally, check everything, start the engine to see if there's any leakage, and redo it if there's a problem. If you're not familiar with this job, it's easy to leak coolant, which can affect the car's cooling system. I recommend watching some tutorial videos to learn the hands-on techniques.
