Heater core is accessed from the engine bay. Remove the hoses, and then there are 4 or 5 nuts and bolts holding on the heater box on the passenger side of the firewall.

While you have it off, it would be a good time to buy new seals too.

If its a factory A/C truck, The heater box is under the dash, & will have to be removed.

If only it were that easy! The last nut/bolt is hidden under the inner fender. Drop the inner fender onto the tire to get access. This of course if the heater is non-AC.

I agree also. That last bolt is difficult to get to. I had to take off the passenger side front fender to get at that last bolt. It might be easier to remove the inner fender though.

Doh! Good point, and thanks for clearing that up... I came to realize after I posted that I replaced mine when the entire front end from the firewall forward was off the truck.
