Stupid question on A/C high pressure hose
95 ZJ 4.0 with ATC, 114K miles
Had the air conditioner dyed.... the leak is in that big hose right off
the output of the compressor that goes down to the radiator. Is leaving
behind about a cubic millimeter per week of heavy dyed oil. And the
local forecast is just under triple digits for a week or more.
Is hose this the one that has the fixed orifice inside?
If this hose is replaced, is it a good idea to have the rest of the
system torn down and O-ringed while at it, or is it safe to replace just
that hose then pump and refill?

in the hose or at the bayonette joint? You can vent and replace this
and refill the system without having to vac it out. (not good for
the environment) A little tweek can stop some leaks but be careful as
the aluminum can strip and that gets real expensive.

If your talking expansion valve, that's in the one that runs to the evaporator.

Most shops suggest new rings all the way around or you will be
back fixing more leaks. Plus they have to pump it down anyway.
I tend to agree.

Looks like you are correct about it being at the joint right there at
the compressor since the wetness from the oil/dye starts so darn close
to that end of the hose that I dont see any unwet part. And I don't see
any abrasions or obviously over wet spots along the hose as I would
expect if there were even the tiniest pinhole a tad further down.
I'll replace the hose... I once tweaked a Volvo A/C hose and the thing
scared the living p** out of me when it blew at a stoplight in LA.

The full O ringing was my idea, but think I'll insist since the darn
pump down and refill costs more than the rest of the work.
