I used Cascade Dishwashing Gel in my radaitor - 'bout a week ago. 1/2 Cup in radiator with 2 1/2 gals water in it. Covered part of the radiator to get it up to 200 degrees. Ran it on highway at 40-45 mph for about 1/2 hour. Drained out a whole bunch of dark brown looking junk. Repeated the process an drained out some weak tea looking water. Inside of radiator is now clean as whistle. Truck (28 pickup) has a 160 degree thermostat in it. It normally runs at 160 so tho get it to run around 200 I had to do some experimenting with the size of the cover in front of the radiator. Ken
