I need some help!!! I can't get my heater box out. My dash is completly out, but i can't figure out how to get out the heater box. i see the bolts and nuts sticking through the engine side of the firewall, but when i turn the nuts, the bolts spin too! I can't even see, little on get to the bolt heads on the other side to grab them.......any advice???

They are studs (4ea) so doesn't matter if they both turn
Removed mine yesterday (97 TJ) without removing the steering wheel & complete dash panel.

Stud meaning threaded on both ends with a nut on both ends??? That explains why when i turn the nut, the bolt turns too, but i can't get the nuts off!!! What is the trick for them???

No nut on orher end
Stud has fine thread on the firewall side ( where you can see inside engine compartment) and there is a course thread on the other end which screws into the plastic plenum these two threads are seperated by a hexagon fixed washer which seats against the plastic.
So if nut & stud are turning together it should come out with no problem
Could send a picture if you want ( just give me an e-mail address, as i seem to be unable to attach files over the allowed limit of 109K ( or somthing in that range)

Heater Box

I seem to have found the end of the instructions...FSM is on the way...in the mean time, I'm at the point (I think) where I need to get the heater box out. Just want to make sure I have the correct bolts behind the firewall before I go taking them out...I don't mind spending hours ripping out my dash, but I'm not a mechanic and am not as comfortable taking out random nuts under the hood...Let me know...THANKS!!



BTW, Thanks to scorpionkill for this write-up!

wow, if that doesn't look like a huge PITA. Easy to see why having a shop replace it is so expensive!

I haven't seen this job turn out to be easy in any vehicle. This part is so close to the firewall that I can't understand why there couldn't be a better design.

It's definitely long, but I haven't found it all that troublesome other than not being sure which nuts to take out to get the heater box off...just long.

I'm learning a lot, that's for sure...

Anyone?

Can anyone comment on my last post (quoted below)? I'm ready to go, but without the FSM or confirmation from one of you experienced guys, I've got to wait.

THANKS

One more try

Ok, one more try on getting someone to take a look at the pictures and confirm the nuts are the right ones to take out to remove the heater box...

Much appreciation!!

Last time I'll ask...

Are these the right nuts to pull off to get the heater box out?

Thanks and Happy Presidents' Day

Update: Found one more behind the battery thanks to someone from one of the google groups. Also found a mount inside the cab near the fuses. The guys says there's one more somewhere??? Anyone care to let me in on the secret? The new core came today, I'm chomping at the bit!!!
