Does anyone have a vacuum diagram for a 1986 Ford F250 with a 460 that pertains more specifically to the climate control system set up? It has a/c and standard heat package. I am needing to chase down vacuum lines and make sure everything is hooked up to the right spots. The one under the hood on the radiator support I think pertains mostly to the smog control stuff that is no longer on my truck. Thank you to anyone who can help

 

i might have what you need. is your truck a california model? is factory or dealer a/c?

 

I dont believe it is the california truck, in fact I am near positive, it was originally sold here in Oklahoma at a local dealership, it came stock with a Holley 4 barrel and it did have the A.I.R equipment on it, but that has all since changed. It is factory A/C though. It is a XLT lariat edition. If you have one I would really appreciate it. Thanks Danilo

 

ok, here is the deal. i have the factory service manuals for 1986. it covers f150 to f350,
e150 to e350 as well as broncos. i looked through the manual and found a diagram listed as "Manual A/C-Heater System Vacuum Diagram and Selector Test". i believe this is what you need. i will post it as soon as i can. i am going to try and scan it right now.

 

Thank you so much, this thing is driving me crazy trying to figure it out. I truly appreciate it.

 

ok here it is. it's an adobe file. if you can't open it let me know.

 

That is going to be most helpful, that shows me everything and exactly how it is all supposed to work. Thanks so much

 

no problem Dk. enjoy and i am glad i could help.

 

Danilo, I thank you for that most helpful diagram, with your help I was able to isolate the problem, it is actually the mixing door at the beginning of the plenum, it has broke loose from the hinged part that is attached to the plenum. I was wondering if you had any tips, or directions on removing enough of the dash to get to this and replacing it. Thanks

 

hey Dk, glad you isolated the issue. using the diagram can you tell me what door you are talking about. is it the door near #1 and #2 on the diagram? i want to make sure i am on the right sheet of music and i will get back to you.

 

If your looking at the diagram I believe you would call that near #1, its the door right after the temperature blend door

 

I am in need of the vacuum diagram for an 86 E350 (motorhome) with a 460. Anyone know where/how I can get one?

 

The emissions diagram should be on the radiator support of your chassis cab.
Or are you looking for the climate control diagram?
What is missing/leaking?

 

Jim: I had looked for the emissions decal but could not find one. There was some of the emissions equipment missing so I am trying to get that put back together. Knowing that these decals on a van are often on the under side of the hood, this morning I removed the under hood insulation and found the decal there. Looks like I can figure it out from there.
Thanks
