1999 Ranger heater core replacement

Hey guys,

I am sure this has been asked before but the search engine is down and I need to know what it is going to take to replace the heater core in my 1999 Ranger SuperCab 4x4. It does have A/C. I use to turn wrenches for a living but do not have a GOOD current repair manual such as a Mitchell Manual with an ac/heat section. Any help is greatly appreciated. Thx.
