Stan, visualize the front of the engine. You have to catch the crank pully which sits right behind the aftmost lip of the shroud. How I have done this is to pull the shroud off the radiator, lift up and lay it over the fan. Sometimes helps to remove cover on distributor. Loosen tensioner, remove belt from pulleys and work it out around the shroud. Same with replacement, work the new belt in over the front of the shroud and mount to pulleys ans so on.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
