I got 4 gallons of 50/50 dexcool to use after the flush. Going to flush the radiator repeatedly. I am also going to flush the block until the water comes out clean of the lower radiator hose. Then I am going to flush everything out the block drains. Scrubbing all the crap out of the overflow tank as well. After it's all done I change out the thermostat, upper and lower radiator hoses, heater hoses as well. Already did the ones on the bypass pipe. Water pump should be ok as it only has 20,000 miles on it.
Car never had a cooling issue. So not worried about that. The dexcool just has 160,000 on it and never been changed.
Changing out the belt tensioner as well. Taking a road trip from Nebraska to Michigan next month and wanna be prepared
