Funny, I just got done an hour ago replacing mine!

To replace it, you will need to remove the radiator then remove the fan and fan clutch then pulley wheel behind it, then lift the spring off the belt tensioner, ( I used a large pair of vise grips and pull like hell upward) un-bolt (center hex bolt) the tensioner, also unbolt the shock absorber from the head and pull it out.

I re-used the roller wheel, and shock, just swapped it over to the new tensioner. You probably should buy those two items new along with the tensioner, they are all separate, I just wanted to save a little money because there was nothing wrong with wheel and shock!

I did also put a new ribbed belt on as well as a new fan clutch.

You can order a new tensioner from just about any supplier, but Fastlane has them too. ...............BB
