Changed it because it was leaking or because it keeps plugging up?

Sounds like this could be caused by a chemical reaction called electrolysis within the coolant, check this link: http://www.4s.com/Upload/Four%20Seasons/documents/Tech%20Tips/English/4S%20350%20ELECTROLYSIS.PDF

ok i tested the electrolysis level and i got a reading of .200 VDC
im going to clean the grounds anyway for safety but could there be anything else that would cause it
