inspected and that accumulations of dirt, dead
insects and leaves etc, are removed to ensure
that the efficiency of the system is not impaired.

Compressor Drive Belt
A/C
0.315 in. (8mm)
TENSION PULLEY
CRANK PULLEY
G140D01A
The air conditioning compressor drive belt
should be checked to ensure freedom from
damage or excessive wear and correct ten-
sion. The belt tension is correct when the belt
deflects by about 0.3 inches (8 mm) when a
force of 98 N is applied to the belt halfway
between the compressor and crankshaft
pulleys.
Adjustment of the belt should be entrusted to
a Hyundai authorised repairer.
SG140C1-E
Checking the Refrigerant
1. Start the engine and run at idle for several
minutes with the refrigeration system run-
ning at the coldest setting.
2. Open the bonnet and inspect the sight glass
on the top of the receiver dryer.
3. If the refrigerant charge is insufficient, a flow
of bubbles will be observed through the sight
glass.
4. If the refrigerant charge is satisfactory, no
bubbles will be observed through the sight
glass.
CAUTION:
Running the air conditioning system with a
low refrigerant level may damage the com-
pressor.
SG140D1-E
Off Season Maintenance
The air conditioning must be run for ten minutes
or so weekly during periods when the system
would not normally be used to ensure that the
compressor and seals are lubricated. If this
precaution is not observed the compressor seals
may become stuck to the compressor shaft and
damaged when the system is next used result-
ing in a loss of refrigerant and damage to the
compressor.
