When I first flushed the coolant on my Grand Marquis, I used Liqui-Moly Radiator Cleaner. What came out was brown fluid, and I had to use over 20 gallons of water before the system would run clean. However, there is still dirt in the cooling system and I'm looking to flush it again soon.
In the mean time, would there be any harm in adding the said Radiator Cleaner to my coolant for some clean-as-you-drive? It's a slow cleaner, and consists of a soapy solution. Thanks!
