Need to replace Heater Core!!
Ok, Im new to the 1983 280zx. I bought this car a few days ago, and the guy who sold it to me said the heating core leaked in the car. The heat doesnt work in the car, and I dont know how to replace the heating core. Do I need to take out the entire dash, or can i take out the Glove Box and get to it??

I just changed mine out and I don't seen how you can do with w/o taking the entire dash out. I ended up removing my entire dash and the crossbar under the dash. when I first did this tho I forgot about the 2 bolts holding the A/C controls to the dash tho.

If you need to change the hoses from the engine to the heater core then you can only take the glove box, and the panel below it . But If you need to replace the whole heater unit , then just take the dash out.. Its actually very simple ( plus you will have some working room)

I just replaced me heater core and my heater valve in my 82 280zxt. And I did it with out taking out the dash. It wasn't that hard and didn't take that much time. A few years ago i tried to pull the dash out. It took way to long and to much work, so I gave up. Some people say its easy but I don't see how, i wish they would show me or do a write up so I could do it that easy.

Oh hai... dash removal: https://www.zdriver.com/forums/280zx-s130-forums-77/remove-dashboard-25586/
Dash removal process:
-Remove steering wheel (18mm nut?)
-Remove knee kick panels
-Remove entire radio unit
-Remove all 10mm bolts at mid level
-Remove vent control border & then you will see 2 more screws)
-Remove phillips screws at windshield
-Disconnect wiring harnesses @ passenger door A-pillar
-Pull dash out several inches
-Get under drivers side dash, reach up to speedo cable, & twist off.
Out comes dash.

I've removed that unit and dash once before so it only too me around 3 hours or so to changed out everything and have it all hooked up. But if you haven't done it before I'd give yourself the better part of the day if not a weekend just to be on the safe side.

The dash is about an hour job if you haven't done it before and you take your time. Finding the necessary bolts/screws to remove is what is a pain. It does help if you have a friend to help you lift out the dash from the car since most of the dashboards I've seen are brittle from age. It took me 3 days to change out my old heater core, swap from auto to manual a/c and change out all the vacuum lines under the dash.
I figure if you're just doing a heater core, it'd take you half a day on your first try. It'd be a good idea to change the heater control valve and heater hoses while you're at it so you don't have to repeat the process again for a while.
