how do you put a heater core into a 92 skylark?

i really need help becasue this is my first car and am unable to pay the money to get someone else to do it please please help...

Sorry for the slow reply. If you are still wondering, the heater core on a '92 should be accessible from inside the vehicle. The center console, ductwork, and core cover can be removed from under the dash, exposing the heater core and evaporator core case (if it's air conditioned).

Try going to Amazon.com and getting a Chilton manual for GM cars for these years. They have the procedure listed there and the manuals are dirt cheap nowadays.
