the boxes with the vac lines infront of them... how do i move those or take them out?

zenzee

Color them with paint or other material so you know where each hose goes respectively.

Mitchf253

I understand that, i need to know how to get the plastic box things out from behind those

There are 10mm bolts on tabs at the firewall on the bottom of each box. I would explain more but I am Mobile Phoning right now.

Alright awesome. Thank you!!!

That vent towards the left side of your picture is the top of the housing that holds the heater core. You can remove the whole unit and then swap cores.

I tore all of that out of a junkyard 280ZX in record time. It seemed to all makes sense when I was removing it but that was years ago.

What about the ac lines are they ok to just disconect?

NismoPick

^^^ I thought you were installing a heater core?

The heater core is located in the center control box... you don't touch anything else.

Mitchf253

Oh i figured i had to take everything on the left of it to get to it.... So that center piece just comes right out?

NismoPick

Yesh.

Mitchf253

Is it just two bolts cause i couldnt get it loose

evandubya

there are 2 bolts on the transmission hump and 2 more one on each side in the middle on the firewall.

Mitchf253

Ok so now how do i get it out of the housing. Sorry guys butbthis is a puzzle for me

Mitchf253

this is where i am... thank you guys so much for all the help

Mitchf253

My only queation i have left is what hoses go to the heater core. Like i said befre the previous owner disconnected the two, and looped them under the hood. How do i know what ones are what. Thanks guys

The line coming out of the head goes to the right side, the return side (left) goes back to the water pump...
