In this video, we're going to be replacing the radiator drain plug on my 1994 Chevrolet c1500. For what it’s worth I have the 4.3L V6, but this part also works on the V8 model OBS trucks.
In this video I use the BlueDevil Pour-N-Go Radiator and Block Sealer that I purchased from AutoZone on my 1994 Chevy C1500 with the 4.3L V6 to see if I can fix a coolant leak.
