the dex cool does get nasty once its been contaminated....i would flush the hell out of the system.....take the rad hose off and point it straight down into a bucket, start the truck and wait for the engine to get rid of the coolant thats in it, take your trusty hose and stick it into the radiator and let it run till the water comes kinda clean....reattach hose, fill with coolant, check for leaks....enjoy
