Get a price from a mechanic. Ask why it's so expensive. They will explain the job to you. It's hard to get it apart without breaking plastic parts. It's hard to get it all back together so everything works. Every wire, every vacuum line etc. If you had a warm, spacious, comfortable place to work indoors, and gave yourself a couple of days to do it... maybe you could. Especially if there was someone experienced who would drop by when you got stuck to advise you.
To re-place a heater core first open the drain located at the bottom of the radiator in your Chevy Silverado. Drain the coolant in a container that has a lid and cover to store it for re-use. You should then disconnect the negative of your battery and wait for a few minutes so as to not accidentally deploy an airbag.
