has anyone ever heard of a cooling system flush and fill which did not involve actually draining the fluid and replacing it? I took the car in a few weeks ago, and I watched the entire process. The guy removed the upper hose, connected it to some piece of connecting hose, and then connected the other end of the connecting hose to the radiator. So, instead of hose-radiator, it was hose-hose-radiator. Then he poured flush chemicals into the radiator, ran the engine for 10 minutes, removed the connector hose, and sent me on my way. No power flush machine, no flushing with water, no draining. I'm starting to get this really bad feeling that my car was not serviced correctly.
