Thanks a lot for this, so far you are the only one who has experienced
the sort of upgrade I had in mind and hopefully within a reasonable
Balance what you have done with the view of the accredited a/c installer
I spoke to who essentially said an 18 year old system in this
non-standard vehicle would be so affected by deterioration, corrosion,
poor sealing etc in so many components including the long hoses,
realistically no one in the industry with typical high labour costs and
overheads would touch it. Only a complete new system would attract a
warranty. In his view, the removal and replacement with a complete new
system would be prohibitively expensive. He did say though to try and
find someone with lower overheads such as the mobile a/c accredited
installers, even then it would probably have to be treated as a "labour
Ok so please give me your thoughts on the following ok ....
I believe I can get a new modern compressor with double pulley that
bolts straight on to the existing bracket. The compressor pulley will
line up correctly with the drive output pulley.
I expect the o ring connectors on the new compressor head will be set
up/located differently to the existing flair connectors on the old
compressor head. So do you think that cutting off the hose flair
fittings and replacing them with the newer o ring fittings, the hose
will still be long enough to attach to the new compressor head? Worst
comes to the worst, I believe there are adaptors available.
The receiver-drier as a matter of course should be replaced.
As you suggest, replace the X.T. valve.
So from what you remember, you re-used the old front condenser (in front
of the radiator), the in-dash evaporator, the thermostat and pressure
switch as well as the 2 very long rubber refrigerant hoses. The whole
system was evacuated of contaminants then regassed with R134A
refrigerant, tested for leaks and it passed ok?
Are you aware of any other issues and does the a/c system still hold
it's gas ok ... that is, it's still quite cold even now when you use it,
some 5 years later?
Do you run it periodically to keep the seals moist and do you have it
serviced annually or not?
Thanks Yurik, I appreciate your help and guidance.
