SOURCE: heater core replacement
It's one of the easiest cores to replace that I have encountered. Disconnect heater hoses at firewall. Probably doesn't matter about hose placement, but I always mark them just in case. To remove the fiber cover under dash, take a flat blade screwdriver and pry out the center pin of the expansion clips that hold it in place. There are four 5/16 head screws that hold the bottom/drain tray cover. Core will pull through the firewall and then down. You may have to silicone/glue or replace the foam seal strips on the new core. Before you install the core, check the distance between the inlet and outlet tubes to ensure they match the openings in the firewall. This saves time. It helps if you have someone on the outside to guide you when stabbing the tubes through the firewall. Replace bottom cover. You may have to hold one of the tubes when reinstalling the first hose to the core. Replace any lost coolant and check for leaks prior to reinstalling the fiber cover. If the cover seal is in good condition, any leak should drain through the firewall, otherwise it may leak inside cab. .

allow the system to cool down
take radiator cap loose to release pressure
once pressure is released tighten cap
loosen clamps on the heater hoses in the engine compartment on the pass. side of firewall.
plug or cap off the heater core tubes to prevent spillage when you pull it into the truck
place a trash bag on floorboard in case spillage occurs
remove the five screws holding the heatre core access cover, three on top and two on bottom
carefully pull heater core back and down and remove it from the dash
install is reverse
Hope this helps
