Believe it or not, the only "chemical" you need to flush a radiator, is Cascade powdered dishwashing detergent.
Industrial / Big-Rig diesel mechanics have been using it for years.
Drain your radiator at the petcock, fill it back up about 1/2 way, add 1 to 1-1/2 cups of Cascade, then top it off with water.
Get it up to operating temperature and run it (high idle or on-road) for 20 minutes, then flush with tap water.
I work for a company that has a LOT of off-road diesel equipment (CAT
, Cummins, Komatsu and etc.....). They utilize this process quite often.
Cummins Operation and Maintenance Manuals for B Series Diesel Engines: Coolant System Flushing: Use 0.5 kilogram (1.0 pound) of Sodium Carbonate (aka Cascade
) for every 23 liters (6.0 gallons) of Water.
That sounded like a good idea until I read that the second chemical is sodium silicate which is what we are trying to get rid of.
