Air Con

[pheobe]

Hi can anybody tell me how much gas and oil is required after blanking rear air con off on a ls 430?

A leak on the rear pipes has resulted in me going down this path, I was also wondering why these pipes can't be repaired joined or have a small section fitted to replace the leaky section

Thanks up front Eric

It may be best to consult a car AC specialist, they have the weight and amount of pag oil for a complete system so there would still have to be some guesswork with part of the system removed, as for repairing the pipe I've no idea but I don't see why it couldn't be done apart from an inaccesible location perhaps. Again ask the AC experts is probably the best way forward.

Hi Steve thanks for the prompt reply, it was the AC guy that was asking what difference blanking the rear AC off would make to the amount of gas required. They are prepared to blank off as requested. Regarding the repair to the pipe it was just a blanket can't be done, not the location of leak,not trying for more work,not even an offer to make one.

The requirement of Gas and oil would be the difference in the amount required for a ls430 with rear A/C and a Mark 4 LS400 which as no rear A/C the amounts are available to the A/C guy through Manufacturers info so he should be able to deduce from that the amount required,which is the same as a Mark 4 LS400.

I can't remember the exact figure but when I had mine re-gassed the guy said it's around 600 grams of gas but with the rear ac it's around 900 in total.
