Refrigerant and compressor oil for air conditioning system

I searched this forum and the rest of the Internet, including Suzuki's service manual, for information on which types and quantities of refrigerant fluid and compressor machine oil are needed for Jimny's air conditioning system.

However, the only information I found was that I need R134a type refrigerant fluid (the ubiquitous one). I found that in Suzuki's service manual.

What type of compressor oil do I need?

What are the required quantities of both to fully load the system?


Is the air conditioning system the same in all Jimnys, older and newer, petrol and diesel?
Mine is diesel.

I have just found one Hella's catalogue which lists required quantities of refrigerant and oil for various vehicles' AC systems:

www.autototal.ro/dmdocuments/Catalog%20B...g%20Behr%20Hella.pdf

It lists that Jimny requires between 500 and 600 grams of R134a refrigerant, but 0 ml of oil !?

not sure but I think the oil is simply in the refrigerant (can also put dye in it to show up should there be a leak.

IMO however, from knowledgeable mechanics I have been lead to believe that it's best not to change/recharge the system as experience has shown that once you do, problems start i.e. compressor failure or bursts - could be that the system was about to fail anyway, or maybe the added strain of a newly fully charged system causes failure

anyway ... my compressor seized and failed a few months after a recharge - and to be honest the recharge didn't make the aircon any better than it was in the first place, just hoped it would.

G engine and K (Diesel) charges at 550g
M engine needs only 430g.

STP aircon recharge service or DIY kit offered at Halfords. Charged my Jimny early this year as the refrigerant pressure had dropped below the cut in point preventing the system working. Once charged to the correct pressure its been fine for the last 8 months and is still going strong. The STP solution contains all the system needs ready mixed and also contains a leak sealer.
Will not seal a massive leak, but more than adequate for a slow leak. You can also get the kit on Ebay if you are anti Halfords.
Been loverly and cool all summer

What do you suggest as an alternative to recharging then?

Before you comfirm the compressor oil type, you'd better  to make sure you know the type of the compressor ,so that you can comfirm the oil according to the specific information.

Last summer I had to service both my Swift and my VW. First the AC pump in the Swift (same as a jimny) made horrible noises. Fault finding thru listening with a stick at the pump, and checking for variations during on or off AC.
At the time my daughter had the car at her university sme 8 hours from where I live, so I told her to cut the drive belt with a knife to shut it up. She got a quote from a shop down there for fixing it about 1500£ (norwegian prices!). I changed it next time she was home for a used one bought at a wreckers. I did the job myself and paid 150£ for parts and 150£ for the recharge.
no problems after this except the pulley died so changed it for the one from the broken pump. Now works great.

So the VW. This is a bus so AC aluminium pipes from the engine all the way to the back of the car where the condenser is. four pipes cost about 500£ each and the shop wanted to change them all so quote was 2500 in total for the job++.
I got to it myself again had the shop fill the system with the green dye stuff so I could find the leak. after alot of searching I found it. Car has been undersealed so it was messy and not so easy to find. changed the pipe with leak and was lucky to not destroy the couplings on the pipes got it all seald up and system recharged. still cost me 700-ish in parts and recharge.

So I spent many days of my summer holiday saving maybe 3000£ compared to the shop price.
still would like some time off this summer instead of doing servicing to the cars:)
