Hi All
Forester 2009, AC system never been serviced, still was blowing some cool air 15 year later.
The AC system has been recharged at service shop.
It's blowing cold arctic air however two things 1) the engine revs dip low when idling and AC kicks in 2) observed AC clutch engages and disengages quite frequently, like every 10 seconds or so
I must say I never looked at the AC clutch before but it doesn't look like this is normal?
I would like to check AC low pressure ( and by doing this to make a judgement on the correct quantity of refrigerant in the system). I've been googling for hours and discovered and listened for tens of videos now, that explain how to recharge AC system, however I couldn't find a single one that explains how to check the pressure and that's it.
I am hesitant to connect manifold gauge to LP/HP port, because I don't have vacuum pump and concerned that I would let air into the system. And then, the hoses that come with the gauge are quite long, they would grab a fair bit of refrigerant I imagine... and then I found a simple $8 tool that have just one short LP hose and the gauge... can I just connect that thing to LP and check pressure? Should engine be running when I connect? or should I connect first and then start the engine?...
It's seemingly simple operation, but as I have never done it before there too many questions that introduce uncertainty and I am reluctant to stuff it up...
Appreciate any pointer!! Thanks
