factory heater

Could someone post pics of an early cj5 heater box assembly switches etc for my 59 cj5. I need to know what style to look for on eBay so I can have the correct one. I don't think I'm supposed to have vacuum diaphrams on it but I don't know what style is for what year. And do the wagons and trucks take the same heater assembly or are they different. I need pics of every piece of the heater assembly thanks

 

I'll shoot some pictures of them in the morning..............that system does use two vacuum diaphrams that are regulated by a vacuum & switch panel that mounts under the dash............As far as I know they were pretty much the same from the early 50's till the time AMC took over..........it mounts under the dash on the drivers side.

 

The heater on my 57 cj5 used choke cables to control the heat valve on the heater hose and the defrost butterfly. The controls on the old Jeeps I looked at, mounted the controls in the middle of the dash. I bought a fan solenoid from Walcks. I could not find the original cables so I bought universal cables at NAPA.

 

Correction disregard solenoid. I meant to say rheostat

 

My '55 has an under-dash style heater, located on the passenger side. Really just a heat exchanger with an anemic fan to stir up the air a little, the water lines extend through the firewall.. I can get you pictures if that is the style you are looking for. The others I've seen are the box style that mount on the engine side of the firewall and blow onto the driver, where they might be of some real use....That is probably the one you want....I have no idea when they changed over to that through the firewall style that has a fresh air duct from the grill area..

 

Yea im actually looking for the big box under the hood with the blower inside the cab and 3 cables in middle of dash one that i dont believe has any vacuum anything i think it should be manual cable everything but im open to other ideas also. my jeep still has punch-out points not punched out where the factory one should go. and the only heater i have is small under dash on passenger side that says willys-overland. kinda looks like an old soda machine its probably out of a truck or maybe an aftermarket heater of the time but i dont know.

This is what i have now and i dont know ANYTHING about it (i actually have 2 of them) it actually works just now well and the heater core doesnt leak. if you could tell me about this one i have now that would be great.

That s not what I have. Mine goes thru the firewall on the drivers side with blower portion under the dashboard. Hoses run from the blower to a control box.My info is likely not applicable.

 

Work in Progress, here is the 4 pieces that are normally used,


The Large box on the top with the two copper pipes sticking out on the left and the large air intake hole towards the bottom is the heat exchanger that house's the Heater core and has a cabel operated trap door that allows cold air or heat. It mounts on the drivers side firewall in the engine compartment. The Large tube hooks up to the grill area via a 4" flexible hose.

The large box below that houses the squirrel cage and fan motor that mounts to the firewall above the clutch pedal. The box that hangs off of it to the right is vacuum controlled to direct hot air to your feet or to the two round defroster vents on the top which hook up to a plastic diverter mounted to the base of the windshield frame.

On top of the first box is a dash mounted vacuum control that has a fan switch and 3 vacuum switches and the cable setup to close off the heat or fresh air.

This stuff was pretty antiquated to say the least but this is the Standard Factory Jeep heater for that period from about the late 50's till 1971.

I believe this one is still back in storage if interested PM me and I'll go look for it.

 

My 60 did not have anything vacuum just cable operated - 3 knobs under the center of the dash - one with a reostat for the fan There was a cardboard plenum with a cable operated butterfly that connected to the box under the dash. The under hood box and the box under the dash look similar to the above pictures but the extension where the defroster hoses connect was cardboard. The defroster duct was also cardboard. I believe the one in the pictures above is a newer model later than 60. Walcks had a plastic replacement for the earlier cardboard plenum and defroster duct which was all crumbled.

 

I made what were the deteriorated cardboard ducts out of aluminum flashing. I was given a plenum also made from flashing with the original deflector installed .I used a pvc reducer mounted on the plenum for the defroster hoses I had three old parts jeep and none had anything resembling a vacuum setup.The old manual cable setup is pretty easy to work with.

 

from what ive seen on ebay and elsewhere it seems like i should have this setup jossar is talking about. 3 manual cables in center of dash and no vacuum of anything and in my owners manual and other places ive seen early cj5's with pictures of the dash area that have solely 3 manual pull cables with no vacuum.

 

Our 1964 had vacuum cans under the dash. They did not work so I put on cables to control the heat and defrost. It really can't heat the cab on a cold Wyoming day. It will clear the frost off the wind shield once the engine gets warm.

 

My '67 has the vac can setup, but the core and blower are mounted on the right side- not the left like everybody else's. The auto-idle setup for the welder sticks out off the exhaust manifold, so no room for the heater core assembly.

 

What is the source of vacuum for the heater vacuum cans? Intake tap? Would the dual fuel pump be able to provide enough?...or maybe those cans require minimal vacuum to operate....

 

My '57 Restoration has the in dash cables as mentioned above.

 

Hmm the heater in my '57 is a silver box with three doors on the sides that have to be opened on closed by hand manually?

 

Does yours have the cut outs on the driver's side firewall for the later "Early CJ" heater? Mine also has a passenger side heater similar to that but thinking dealer or aftermarket installation. Mine has the drivers side heater as well but with cable controls as I indicated. I know some of the real early ('55-'56?) CJ's didn't have the heater cutouts for the driver's side heater used in the later Early CJ models. I think Howard posted pics of this in the past.

57willy's heater is the same box as what's in my '64 Peterbilt. Can't remember the mfg- might be "Hadee"? from what was left of the sticker.

 

My '55 is just like the first drawing. Three heater mounting bolts and two larger holes for the hoses. I also have the little panel marked "?" It's cover is removable.. I wonder what it could be for...maybe another holdover from the M38A1..
