To check for overcharge:
- run A/C on high speed for 2 minutes,
- idle engine with A/C on for one minute more
- while loking on the sight glass, switch A/C off
If you see the foam and bubbles for about 10 seconds after shut-off
, the system is charged properly
, if glass clears right away
, the system is overcharged.
Also, the overcharged system cycles frequently from on to off.
