Check the Air-Conditioner Sight Glass
The air-conditioner sight glass should be checked to
see if the system is functioning properly.
The receiver/drier (1) is located on the rear, left hand
hood support. Check the sight glass (2) on the top of
the receiver tank every 250 hours. If clear, the system
is in good condition; if bubbles flow across the sight
glass with the engine running, the system may be low
on refrigerant. If the glass is cloudy, it is an indication
that the system is contaminated with moisture. When
moisture is present, the dryer will have to be replaced
by a qualified air-conditioning service technicians.
