air con charge

[ozzyvelcro]

Hi all

Does anyone know the correct charge as I will be topping the
system up over the weekend.The car is a 91 3rd gen.

Cheers Danny

Not sure what you mean by \'charge\'. Being a 91 it probably has R12 in it - now illegal I believe - ozone damaging etc etc. Newer cars have R134.
I had a hell of a job getting mine re-gassed. Now there is a replacement gas which is great so far.
They will just fill the system until it\'s full - probably put a dye in it as well which will show up any seeps/leaks if/when they occur. Visible with a UV light.

The charge is the amount in weight that goes into the system.
Your right about R12 being illegal I have the replacement which is a direct swapover.The charge is quite critical though as to much or to little can cause compressor failure and poor running etc.

Thanks Danny

My Cosmo was on the r12 system there\'s a guy on ebay sells diy aircon service kits and adapters to convert the R12 filler and test port to R134 spec. Easy to convert and fill the system yourself, took less than 30mins on the Cosmo to convert and refill system.Service kit was £34 plus delivery and adapters about £2 each i think. Only took two days for delivery and i\'ve still some gas left from the kit for topping up. http://www.car-air-conditioning-supplies.co.uk/

Does this mean that everyone else\'s aircon has packed up in the hot weather as well?

Mine packed up when i removed the pump and rad for better engine cooling...

Small thread hijack here...

I have noticed my cold air getting warmer, is it easy to get it \'fixed\', and by the sounds of it do it myself?

Mine works but has never been great so will get it sorted tomorrow.
I\'m an air con engineer by trade so I\'ve got the tools to do it but its not something  you can do at home.
Kevin did you vacuum the system before you refilled it?

Cheers Danny

[kev-yorks]

System was fully drained while engine mods where carried out.Red dye into system first to check for big leaks, then UV dye combined with small leak sealer and oring conditioner,oil next then filled with R134a. Just a case of following instructions supplied. Air cons working spot on now, best £34 quid spent this summer as the weathers been recently.
Kevin :cool

[ozzyvelcro]

The reason i ask is that whenever you refill you should use a vacuum pump first to take out any air or moisture in the system but then your looking at spending another £200+.
Still if its working fine then i would\'nt worry to much.

Not sure if this info is any help to anyone, I found it in the manual (it\'s a US manual I have mind you). It means nothing to me, but might make sense to someone who understands air-con systems; -

Heating and Air Conditioning Systems

Refrigerant amount - 600 g
Compressor oil amount cm3 (Nippondenso compressor) - 100-140
Refrigerant normal pressure at 25 degrees C kPa - Low pressure 147-294, High pressure 1,275-1,472
