2nd gen Compressor hose changes

[85_Ranger4x4]

Looks like midyear thru 91 there was a change in the hose/manifold assembly for like a 4.0 Ranger. Anybody ever order the wrong one and notice what changed?

I think the suction hose routing was changed.

Dang, now I gotta hit the JY for more recon...

I’m trying to remember the actual differences between my 90 and 92. I’m pretty sure the suction line was run a little different. I don’t remember a huge difference.

My hope is to use the 4.0 hoses on an Explorer 5.0 setup. The run the same compressor but the Explorer has the compressor where the Ranger has its power steering pump and vice versa.

So I need all the reach I can get, but for me it just has to dodge a carburetor not a full intake manifold.

Seems to me that the older style went around the back of the intake, and the newer style went around the front and under the throttle body. It appears that the accumulator to compressor side of the '90 style is significantly longer, maybe that would give you enough length.

I'm assuming you have a second gen condenser? Ports on both sides as opposed to both on the passenger side (1st gen style)

Yup, second gen condenser.

Hate to suggest dropping $50 on a '90 suction hose but it might work. Might be a hard item to find in a junkyard.

I looked at a bunch of different vehicles from that era on RockAuto and not many suction hoses looked promising. Late 90's 4.0 OHC Explorer had a very long hose and maybe the right fitting at the accumulator, but the wrong one on the condenser.

Would pictures of a '90 Bronco II hose help you? It's rubber out of the evap, turns to the rear and routes behind the 2.9's intake with a metal section, then changes to rubber again to run the compressor.

If he's using the 4.0 compressor, the hoses from your application won't work... they are one piece on 4.0s, two pieces on 2.9s and other stuff from that era.

I missed what compressor is being used. I've got the '90 B2 with separate hoses at the compressor, and also have a pair of later 4.0's (94 Ex's) with both hoses on the single manifold block at the compressor. The '94's accumulator to compressor hose does go around the front.

I could have bought the fittings and made my own hose by now..

According to google this is a '91 Explorer:

And so is this:

Now I know what to look for anyway!

Not sure either really have a whole lot of slack to do what I was thinking about doing though.

That is hard to do when the only A/C system part on the truck is the button on the dash.

I haven't had time to do much more than daydream about it.
