Hi, thinking of topping up air conditioning gas using Ezchill/STP KIT. System dosnt have a leak, as far as I am aware, but dosnt run as cold as I think it did. 2008 model and never been topped up. Anyone done a DIY top up? Thoughts?

Also, is this the HP air conditioning charge point, searched t'internet and haven't been able to confirm location.

Thanks

There is two nozzles the one circled and the one under the plastic hatch just above Former Mod/Member, with the most post & Chicken George Arch nemesis

There is another connection under that small plastic cover above your pointed port.
Don't know exactly which one is which, but the HP port is always on the thinnest AC pipe.

LE: Here, maybe this will help...
