Ok guys I got a 85 f150 non AC winter is coming and it has no heater core so I'm trying to figure out how to tell if it has a high output heater or not
The heater box under the hood will have HI OUTPUT molded into it, you can't miss it if you have it (the lettering is part of the molding of the box and is quite large).
