ANOTHER 4.3 v6 S10 in the shop? Overheated? Parts Failure? HOW bad is it?

Another week, another GM 4.3 V6 in the shop, this time with what is reported as a radiator failure and overheating, alright let's see what's up! Previously this truck had a new radiator installed by us about a year and a half ago, did our part fail or is there something else going on? We LOVE these little trucks on the 80s, 90s, and early 2000s. The S10 and Blazer that shared it's DNA were some of the best most dependable small affordable trucks around, and we are more than happy to keep them out on the road! This one just needs a little care and TLC, hopefully there aren't bigger deeper issues!
