You get the eagle eye award for the day.AN(Army-Navy - usually Aluminum)
JIC(Joint International Council - almost always Steel)
Both are same 37° taper; and, for all practical purposes, completely interchangeable.
Curious nosy minds need to know; I spy a big TEE and hose-clamps in that big A/C line that goes along the firewall and across the engine; what is going on there ? Possibly a refrigerant line to a remote evaporator ?
That sighting begs the question, as such things go, refrigerant lines are not under anything close to what would be considered high pressure; yet, it has been indoctrinated within us since the beginning of time as we know it that we need some scientific hose-making expert to crimp together these hoses.
I just wonder, if the line fittings had decent barbs or a single hose-nipple barb, if a good double-hose-clamping with quality hose clamps, like those recommended for fuel-injection hose, would not be more than sufficient for clamping the hoses to the hose-ends.
In my experiences with having trusted shops make up A/C hoses, I have had more than a few leak at the crimp after the system is charged; and, to prevent the hassle of losing expensive refrigerant, taking things apart, having the offending hose re-crimped, putting it all back together again and pulling another vacuum, I have on a few occasions put a couple of good hose-clamps over the crimp and managed to stop the leak with no further involvement.
I also have to wonder whether, instead of having a bunch of weird-threaded odd-ball fittings with leaky O-Rings, would not one be better off to put JIC fittings on the ends of lines.
There's a rear inside mounted heat coil located on the passenger side at the Bronco tailgate.
I'm not sure if there's coolant lines running back there yet, as I've been focused on the drive train.
The tailgate is rusted badly, I plan on replacing everything with LMC parts in the not too distant future.
I'm planning on capping off the hoses that run to the back until I gain full access to all the components.
Right now the only way to access is to crawl over the 2nd bench seat.
The front part is a 1989 F350 Lariat 7.3 short box, the back half is a 1989 Bronco.
There's a fan switch and some kind of potentiometer scabbed into the dash.
The Centurion wiring is heinous.
They used crimp splices everywhere, ran 10awg THHN wire in parallel for feeders, and the dash wiring is a complete nightmare.
For now, I'm just focused on making the new 7.3 with rebuilt 088 and Garrett fan blow smoke, the now ZF542 spin the shafts, and soon to be '03 super duty axles push the truck down the street.
That's the truck in my avatar.
I got it in 2009, lifted it and used for about 1 1/2 years, until a very shady mechanic caused an engine fire in 2011.
It sat since then until November '23, when I finally had time to fulfil my promise to repair.
