97' Ranger Heater Core
2WD, 4.0L, Ranger w/AC. I smell coolant with the vent on, so I know that the heater core is bad. My Chiltons manual tells me to pull the core from the engine side. AC hoses and evaporator are definetly in the way, I don't want to break the AC system. I dropped glove box, looks like the whole dash has to come out. Somebody help me. Tell me I'm wrong.
How big a headache is this going to be. Any advise would be helpful.

This thread has some very good directions on how to access and remove the plenum chamber so you can replace the heater core:
