what kind of truck?, if it's the 73-91 k5, they are piece of cake, remove glove box, undo cables on box, remove whole heater box, nuts are in engine compartment, whole thing should be about an hours work.

If you have air tools and your inner fender clips are still intact you can drop the inner out and get at the bottom two bolts on the blower box. If not it's find the lower bolts by braille and have to hold your tongue Just right using 1-2 wobbles on a bunch of extensions.

Like so many others here, I have had the pleasure of doing this job,(lol). Seriously though, go to the link that mxfireman supplied for grim-reapers detailed how to. It's not that it's a complicated job, it is just many steps that you must go through.rafterman191 said:

usually I'll holesaw through the inner fender in a round abouts location of the hardest ones to get at.
Changed mine on my 89 blazer and was done in an hour.

Just pulled mine and took about 35 mins.. Not going back in. 
Pulled heater core out of my '73 last night: 35 minutes. Bought new one and installed it: about 20 minutes. Was expecting a harder time. It was a piece of cake.
