A last warning - using acidic treatments like white vinegar may flush/remote the grease in the water pump packing nut that helps seal the water pump shaft. The cooling fan will blow hot rusty water/vinegar through the motor bay and out through the hood louvers. A real mess that also can ruin your paint. I've seen pictures, and it is not pleasant.
