Radiator corrosion usually results from old o r poor-quality coolant o r from using plain water instead of coolant which is still common in some areas of Pakistan. Rust can weaken the metal o r aluminum fins and create small holes that leak coolant. Once corrosion sets in, its often not repairable. A temporary fix might include using a radiator stop-leak product, but these are only short-term solutions and may clog the system. The best fix is to replace the radiator with a genuine o r high-quality aftermarket part. Also, flush the cooling system thoroughly to remove any remaining rust o r deposits, and refill with the correct coolant to avoid future corrosion.
