Anyone know the step by step instructions on how to replace a heater core on a 98 f250 5.4

 

Even though I drive E-Series I found this video interesting............:
I did get a huge laugh at the factory procedure for this, it begins with removing the entire dashboard first, sooooooo NOT necessary at least on the vans.

 

Yes you have to pull the dash part of the way out I have a step bey step guide around somewhere I'll try to find it and post it
