heater core..how complex is it to swap?

i have a 2.2L xtreme n my core crapped out on me...this is something id like to try myself if i could, but it it ona those rip apart the damned truck for a two second swap? just a rough walkthrough bout time n stuff would be cool, till then im gonna reroute the hoses to hold it off....im getting tired of huffing antifreeze
thanks

its not complex.....actually quite...simple..
its getting to it thats the Bi#%H!!!
blazer lt has a link to a how too guide....if he reads this maybe he can point it out.
i recently did the core on my 93 4.3...tooke me almost 4 hours.....and cost my 55$ core/fluid.
be verry shure you are willing to go all the way..once you start...the core change....its
not that its hard.....its pactience and time.
if you dont wanna do it your self.....most places i went to wanted between $300-400......
and some didnt even want to be botherd...said cores are to much time...and not worth the $$
well good luck ......

I have changed 2 of them on my 92 S-10 4.3 4 x 4. It is a pain to change.

After doing the first one I said I would never changes another one, BUT I DID!

Could not afford the money they would charge to do it at a shop. Took me a bit over 6 hours, but I have physical problems with my neck and head that makes it a bit difficult to hold wrenches and use my arms and hands.

But it makes one feel good to do such a task and know it has been done properly and saved $$$.$$.
