Thanks for the write up. I followed them Sunday when I repl my stock with DeWitts. For me, I unhooked fans from radiator and then pulled the radiator out. It did make removing fan assembly much easier. I then unhooked the wires and removed the fan assembly. I did attached to rad before I put radiator back in. I did mine by myself, which it would have been much quicker and easier with some help. Thanks for posting. What are you doing with your stock radiator?

Wow, I wish I had thought of unhooking the fan assembly and pulling out the radiator and then the fan assembly. This would have cut out 45 minutes.
As for my radiator, I used it as a show and tell for my club. Folks don't really care about this stuff until they experience cooling problems. In fact many of my associates are swearing by the 225 to 230 degree temps for stop and go traffic (not me). I have been attempting to explain to them that settling for this may not be a good thing since there is not much of a buffer for the really hot and humid days.
Other than that, the old radiator is covered and just sitting in my garage. I am holding it for someone that needs one and does not have the money for a install or a new one.

On top of all of that the new hoses were tighter fitting on the new radiator than the old stock ones (wear and heat degradation from the inside out). Also with my old hoses and clamps on the new radiator I could never seem to get the bottom hose to fit tight enough to stop dripping (slow drip). When I used the new hoses and clamps there was not a problem. Consider replacing the bottom hose and clamp at the very least.

Actually this is a great question. Although the stock hoses and fittings worked just fine, I would still recommend getting new hoses and clamps. I decided to replace all of my hoses with the exception of the two small ones on the passenger side. The stock ones fit on the DeWitts just fine but I found myself a bit uncomfortable considering the price that I just paid for the new radiator; another $50 was nothing...new radiator, new hose and clamps, right!
