I have an 87 is with early cooling system that still has heater core and all hoses. Runs fine, but I want to remove the core before it pukes on my feet. Have read every thread I could find about this, but for the life of me, I can’t find any info on how to get to the port on the back of the head to install a block off plate while the head is installed. I can’t even see back there, much less figure out how to remove the hose and barb, and then install the block off plate.
Do I remove the piece covering the blower motor to make room from above? Does not really look like that adds much room, but it may be deceiving looking at it all intact.
I would like to do the block off plate, and also remove the TB hoses and install my OP switch in the block for a coolant pressure warning light, but I do not want to start pulling stuff apart unless I see a path.
If I can’t get back there with the head installed, is there another path that would allow me to remove the core and deal with all the hoses later when I have a reason to remove the head? I have read all of the "“loop vs block off” posts I can find, and what seems to make the most sense if I can’t get to the back of the head is to block off the short hose that runs from the back of the head, and the Tstat housing of course.
