Radiator sprung a leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hello everybody. Got an 04 Blazer with the 4.3 and the radiator sprung a leak last week. Tried fixing it with JB Weld but didnt work. My question is how hard is it to remove the old one and replace with a new one? I will get a new one from Autozone for $130. I read in my Chiltons manual that the PCM has to be removed to get the overflow tank out as it needs a good cleaning. Any help is appreciated.
Thanks

Did the radiator today. Simple as pie. Took maybe an hour.
