If the heater core is leaking, you don't have much choice but to replace it. It's not an easy job though. The entire dashboard has to be removed. That means removing the steering column, all the electrical connectors, and then the mounting screws. After that, you have to discharge the A/C and disconnect the A/C lines. Disconnect the heater hoses and then you can remove the heater box. The heater core itself if inexpensive--only around $50. It's the labor charges that kill you. By the way, the reason a heater goes bites the dust is because the coolant hasn't been serviced often enough. Old coolant enables electrolysis and that eats away at the heater core.

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. .

on the firewall you will see the two hoses going though it,it will have hose clamps on them,remove them,remember or mark witch side they go on,now, under the dash in the passenger side you will see the black box, it has 4screws to it, remove them,then pull the cover off,you will see the coils,get ahold of it,wiggle it towards you,also moving up and down, lightly,lightly, now installing is same but reversed,now i would hold one of the small tubes and install the hose,cause it will slide back and possiably fall out,be carefull,if you are having trouble getting the hose on the tube,use alittle lube,you can do it,just take your time..
