How to replace heater core on 2002 nissan frontier 6 cyl

This is a very major repair; it takes an experienced Nissan technician between 6 and 8 hours to do this job
it is not something I would recommend attempting unless you are very familiar with and experienced at vehicle repairs; it requires extensive disassembly of the vehicle (pretty much everything you see inside the truck between you and the firewall must be removed to replace the heater core, starting with the entire steering column
it also requires special equipment to safely remove the A/C system refrigerant, draw a vacuum on the A/C system during assembly, and to recharge the refrigerant
if you have sufficient experience and the necessary equipment, i would be glad to look up and post the procedure for you, but if not this particular job might be something you may want to consider having your mechanic do
There are a lot of expensive, easily broken small parts that must be removed and the repair procedure is not going to be extremely detailed (as far as to remove, etc...) since it is written assuming you already know how to do most of the disassembly and reassembly...
