1990 S10 heater core replacement

How do I replace the heater core in my 1990 Chevy S10 Pickup? Looks like a pain. If it requires dash removal I may not be up to it. If so, how much of the dash must be removed? THNAKS, Laura.

Not much I I remember correctly.......take out the glovebox.......Behind the glovebox is a panel/cover angled towards the firewall........Some of the 1/4 in screws will be a bear to get too, but they CAN be removed.........Behind the cover is the heater core.......once you remove the retaining straps and the hoses on the outside......the core wiggles out
