How do you drain the radiator on a 1992 Chevy Silverado?

If your truck doesn't have a drain plug on the radiator, just

remove the lower hose and place a container underneath to catch the

coolant. there should be a petcock on one of the lower corners of

the radiator. it would more than likely be on the engine side (as

opposed to the front of the radiator). with the engine cold, remove

the radiator cap, then unscrew the petcock. catch the coolant in

some sort of container as it is illegal to dump it into the

environment. its also very toxic to animals.
