I hope mine never leaks - I don't have that much time on my hands :thumbdwn:

Well, my truck is down for several other things---so
I figure if I can use my time to save some $$$ it is the same as a part time job---huh?

I won this---I think it is a great deal!!

 

[MountaineerGreen]

Looks nice a nice deal

 

[BrooklynBay]

How much is the regular price? Does this one have a warranty? You could get a couple of dollars in scrap metal for your old one.

 

[Turdle]

OK
This and other things has led me to kind of ignore my truck for awhile, to be honest. This last weekend, I warmed the garage, gathered a bit of osage orange (hedge wood) for heat, and basically sat down and stared at my dismanteled mess.
Thanks to xzibita--I am on a roll again. I have the steering colum removed as a module, and the dash is propped up by a box on driver side, totally loose on passenger side--I can see the needed heater core cover bolts--now to loosen the box from under hood , so I can pull it back and access them.I just hope my intake manifold can stay on.
I was following the prcedure in the service manual, for some reason it led me thru removing airbag-steering wheel, then pulling column. This workaround is where I was confused.
There are 5 bolts,transmission indicateor screw, 7 harness plugs, all keyed, and the transmission linkage to disconnect. I made sure to tape the steering whell into position, so it wouldn't rotate and damage the clockspring.
I need to start taking pictures, I'll get more as I put it back together--
This is where I am now--

Are you going to replace the blend door while its all apart?

I like your gauge pod, BTW.

Thanks--about the pod. It is for mustang--fits nicely (or at least it did before all this--). It requires a hole thru dash though---

About the blend door, well I don't have another one. It wasn't in the plan. I was hoping mine was the stronger type lol.
ok-quick, how can I check it?

 

[MountaineerGreen]

He made a good point- I was just about to suggest the blend door thing.

 

[dogfriend]

One of the Blend door fixes talks about how the blend door always breaks in the same place. I think there is a picture to illustrate it. If I didn't replace it, I would at least see if I couldn't reinforce it somehow. JB Weld is a miracle material.

Hello--man, I am on the homestretch now.
I gotta take a lttle break--those under hood nuts threw me.
They were all double nutted underneath the blower housing---

Someone at Ford decided they were a little too easy to get off without the extra nuts. : Ha Ha, what a bunch of pranksters.

I had the pleasure of doing this on my 1987 VW Fox ... back in 1994 or so. A month later VW issued a recall for the problem, and would have replaced it for free. Sounds like the same job here. Steering wheel and dashboard had to come out. Took two of us about 8 hours to do it.

Now I'm wondering if this is where my coolant is going very slowly.

 

[Turdle]

Well, my little helper is anxious to go ride bye bye.

Dash is back in--let's not mention the blend whatever it was---

hey jon, sorry i didnt get to call ya back, i had a really s****y day , but i just realized some thing, are you sure it wasnt the heater control valve, they are pretty common and i havent seen an explorer heatercore go yet, i would double check, but im glad you were able to figure it out

 

[BrooklynBay]

My heater core was a little clogged. I used a tool called the kinetic water ram air powered drain tool on one of the hoses. It cleared it out pretty fast.

Boy I hope not--I looked it over real well, hoses and all.
The leak was dripping from evaperator housing--I found no other wet spots.

Hope tomorrow is better for you

 

[Turdle]

Well, sorry for the delay.
Had some personal issues--but the truck is fine now--and we have heat!!

 

[dogfriend]

and we have heat!!

I still have a recurring problem--which was there before.
I have tried a new HVAC control, but didn't correct it.
It seems my vent functions don't want to switch. All the vaccuum lines are connected. If it is on vent when I start the truck, it will blow from vent, but when switched while running, it blows from defrost only. I am beginning to think it is either the diaphragm in the actuator, or lack of vacuum from my camshaft.
Although, if I rev engine and let off, vacuum goes way over 20--still no vent function switching--the door is all intact and tight.

My reservoir bottle is holding vaccum--mybe I just have a line or 2 crossed still???

I get a real good switch from heat to cold though---
