HP from "D" port on compressor (Red cap if still in place) to condensor to receiver drier.
From there to firewall and then T/X valve.

Return from T/X via firewall to "S" (blue cap) port on compressor.

Then look for the "S" and "D" stamped on the compressor.
IIRC, the S is usually the one that is located near the centre of the head depending on the brand of compressor but without being connected and no gas in it, the S sucks and the D discgarges (or blows) as an easy way to remember or check.

Thanks Alan,

My compressor is Delphi Harrison no 1135920 for your info, I'll let you know if there are letters printed on the caps.

Cheers

Hi Kenny,
I regassed my MkII Xantia aircon and the valve nearest to the radiator is the low pressure. It has a larger valve too.
