Non AC heater removal

[Wes]

I've finally got my dash out, a big relief.
I still need to pull some of the heater assembly, notably the section that protrudes through the fire wall, see below.

I've removed 4 large nuts under the dash that appear to hold the main heater assembly in place but it doesn't want to budge. It looks to me like there is a metal strip holding it in place along with some type of foam gasket.

Help..

I had the same issue. It's just the foam gasket which holds the heater box in place and you don't want to use force since the box is plastic. I soaked the area around the box with Goo-off and that soften up the gasket enough to remove the heater box.

So it should come away after you remove the 4 x 13mm bolts under the dash?
Can't say I know 'Goo-off' will go find some.

Yep

ALSO SPRAY WITH WD40 FRON THE OUTSIDE
IT WILL SOFTEN RIGHT UP

Almost any fluid will do! Just make sure you soak the gasket enough. We used some heat and break fluid to remove the heater box.

Well you could always use piano wire. I just gently pried mine off with no soaking. Mine was just an ordinary CSI heater box, not the CSL heater box within ultra-thin plastic.

How did you use piano wire? There's almost no room to get around the bloody thing. I'll try getting some WD40 in from the top and bottom and see what happens. I suspect using a heat gun may also help. Guess it's jus another one of those pigs of jobs that take a lot of patience?

I was just spitballing. I didn't use piano wire. I used a screwdriver and reckless abandon I guess. The heater box faired well.

It is a tight fit getting it out and in. The four bolts are all that are solid in the fixings. The front where it joins the bulkhead can be softened by fluid or by gentle heat from the front.

I would suggest you practice this by wrestling a few octopus's to get your technique tuned.
