I have another heater related ?. I do not need the rear heater, in fact the motor is shot and I do not want to spend time and $ fixing something I do not need or want. I have already taken the housing off the rear radiator core and moved the core underneath the drivers seat so I could fit a speaker where the rear heater was. I would like to remove the entire rear heater pipe system and core. It looks like where the heater pipes come into the interior there is a t-piece where the rear heater and front heater pipes split. Could I just remove this t piece and insert a straight piece? What size would this piece be, and how would I stop coolant from flowing out when I temp disconnect the pipes to remove t piece? Thanks for any help.
Here's a pic of the heater valve on my '74. Have a friend open and close the knob in the cab, and look to see if the valve is properly opening and closing.
Thanks, I'll probably keep the pipes for the future. I build my own speaker boxes . If you could check I would appreciate it, I would like to have the pieces on hand before I take anything apart, since this 40 is my transportation to get the parts.yes, you can just take out the t-peice. You can clamp off the heater hoses to limit spillage to the coolant in the core. Be careful of those rear heater pipes. They are worth a few pennies on e-bay. i forget the size. it's either 1/2" or 5/8" I can check when I get to the shop.
It might be worth selling the rear core with the pipes. my guess is you can buy a pretty spanky speaker box for what you get for it.
