Air con gas and oil
Discussion
Thanks Graham,
I had mine done last year but can not remember what amounts they put in and they had real problems finding out.
I am back in the UK next week and want to get it done again at quickfit as if they can not lower the temp then you do not pay and it is worth a yearly check for the price they do it at.
Thanks again

Hello all,
Can someone tell me what the grades and quantitys of air con gas and oil that is required for a Sagaris.
Thanks

Hi Paul,Can someone tell me what the grades and quantitys of air con gas and oil that is required for a Sagaris.
Thanks

Approx 725g with 60cc of Pag46 lube oil
But lee put 800g in his recently and worked better for him

Paul, if yor stuck for Pag46 oil, I have plenty if you want some. I took my own oil to kwik-fit and they knocked a tenner off the price...

Having mine done tomorrow as managed to get a valve from power so I'll suggest they put 800g in as well.
Hope all is well bud.Be careful about the 800g. It worked for me (still not sufficient pressure at 725g to turn the system on). I'm no aircon expert and don't know the systems capabilities. 800g worked for me but the recommended 725g may work fine for you without overcharging the system.

I would not get to hung up over the weights etc. Although a standard amount for both the refrigerant and oil is given all systems will vary slightly.
I am lucky (being from an air conditioning and refrigeration background) and undertake this myself as I have all the required equipment. I would recommend the following:
Always try and get someone to do it that knows what they are doing and looking at. Just weighing in the gas and oil isn't always the best course of action.
For example, if your system is just low on refrigerant I would not recommend adding the quoted amount of oil unless your compressor is noisey. If the compressor sounds fine I would just add a small amount of oil to compensate for any loss, if any.
In answer to the question above the low pressure connection is on the suction pipe at the compressor end and the high pressure connection is on the liquid line on the passenger wing,(on my T350 anyway) and are easy to get to.
The best way to make sure your system if charged correctly is to montior the suction pressure whilst charging the system. Mine runs at just under 2 bar which is about right. A system mod you could have done is to have a sight glass fitted in the high side line. When charging you will see the refrigerant passing through as a liquid and when all the bubbles have gone and the sight glass is full of liquid the system will be at the correct charge.
Hope this helps. Its a shame more of you don't live near me as I would do your top ups etc for free and just ask for a little bit of cash to cover the refrigerant!!
Cheers. Lee.

Where about's are you Lee?
I've had some work done on the front of my T350 including having air con radiator replaced as well as some other bits. Due to this I believe that my air con has no gas and oil in it. I'm off to Le Mans soon and want to try and get it regassed. Where should I take it? I'm not really able to go to Coventry to TVR Power where most of the work on my car is done as I can't take the time off of work to drive all the way there (from Cambridge). So I was thinking of going somewhere local, I've been to a local garage that I use for other cars but they charged me £100 last time they did the regassing a few years ago. Is somewhere like Kwik-Fit really able to do a decent job with the air-con?

Kwik-fit did an excellent job with mine - and only charged me £35.All they do is plug a machine into the car and the machine does the rest. As long as you tell the guy operating the machine how much oil and gas are reqd, I don't see any reason why they can't do as good a job as someone charging much more?
I will say my aircon now done is an improvement on the cold blower, but it still is not great. Yesterday in the hot temperatures we had, I had the system on full and I still would have liked to be a little cooler...
Thanks, I shall give them a bell. I have Graham's workshop manual which has all the gas and oil weights (same as listed above) so I shall take that along. I'm not sure if the system is leaking or not at the moment, last time it was tried to be gassed up it leaked from the drier filter but a replacement was found by the garage and put on (not a new one). Hopefully they will pressure test the system before trying to pump it full of gas!
