i thought the problem had been solved last August at a local car repair shop, where I threw about five hundred dollars for a lifetime water pump. The previous pump was tested to be leaking. and they did a coolant system flush, fill in new G12 in.
Yesterday I opened hood to find the coolant was on "MIN" level again. In a week or two the coolant warning indicator will be on. Should I go to buy some G12 to replete ?
