Instructions on how to replace heater core on 1992 Honda Accord Ex

this is a job for a mechanic,have to pull most of the under dash.

Yes, if you are not mechanically inclined, this is something I wouldn't attempt as a first job. If you do have some experience and want to attempt it, you'll need a Haynes manual -- this will contain all of the different steps and pictures so you can do it right.

Would like to get instructions on the best and easiest,if there is one,way to replace the heater core in a 92 Honda Accord,thanks,Dave
