Default Heater core. How Hard?

Dodged all work today to put my stereo in. I was so happy.

Then, I see a drop of Dexcool on the bottom of the heater box.



How hard is it to get that out of there?

It is a 1985.

Can you replace the AC Evaporator at the same time?

Because, if so.. I'll just do both and it will be done.

Do a search for the fast guy method (No I'm not kidding) that's the title of the thead you can do it from underneath the dash.

THANK YOU SIR!


Do you know if I can get the Evap at the same time doing it that way?

You don't pull the dash, instead, pull the passenger seat.

Pull the hush panel, drop the ECM and the door control module.
Remove the support bar going from the door pillar to the dash.
Use a 7mm to take the cover off the heater box.
Pull the cover, unbolt the core, re-install.
Drink beer and laugh at webpage showing guys pulling dash.

Interesting.

"Fastguy" sounds familiar.

I may have even seen that years ago and forgot.

Regardless, screw it! I'll order both and if you can change both with that method, I'll let you know when I try it.

Thanks again.

This is what you will see looking for the heater core. This unit is the C68 AC/Heater.

my understanding is that the evaporator is actually outside the cab, that black box that the ac lines go into. but again check your fsm

No. There is nothing in common with these two jobs.

Pull the hush panel, drop the ECM and the door control module.
Remove the support bar going from the door pillar to the dash.
I don't remember anything about a "door control module". That "support bar" is a challenge. Here's my creative tool: box/end wrench with long 1/2" extension.



That screw in the upper left corner is done by the "braille" method. You can't see it!

I hope you're flexible!

The plastic clips I see mentioned. I guess there are two of them?

I found one part number in a thread as: 20007898

Are they the same or is there another part number? Anyone happen to know what it is?

PS:

The heater valve is broken too. (the little arm is off of it)

I remember seeing threads on repairing that. Just been putting it off.

May as well just do it all at once, as I think that thing has to come off too.

While searching for the part number, I found this. I guess someone from here made a video of it and it is pretty good. Others may find it helpful. (I know I did.)

It is here:


The Part Number is 74800. (Which I believe is a a Four Seasons number)

Woot!

May I get a direct link to the forum, please?

I've searched and searched, nothing showing up.

Supposed to be "fast guy method" in title, right? This discussion?
