G140D01S-GAT Checking the Compressor Drive Belt When the air conditioning is being used regular- ly, the compressor drive belt tension should bechecked at least once a month. To check the drive belt tension, press down on the belt halfway between the engine crankshaftand compressor pulleys. Pressing with yourfinger, you should not be able to deflect this beltanymore than 8.0 mm. If you have the instru-ments to check it with a force of 98N (22 lb.),the deflection should be approx. 8.0 mm (0.315inches). If the belt is too loose, have it adjustedby your Hyundai dealer.A/C

o Replace the filter every 12,000 miles(20,000 km) or once a year. If the car is being driven in severe conditions such as dusty, roughroads, more frequent pollen filter inspections and changes are re- quired.
o When the air flow rate is decreased, it must be checked at an autho-rized dealer.

o Vacuum, crankcaseventilation hoses
Inspect the surface of hoses for evi- dence of heat and/or mechanical dam- age. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessiveswelling indicate deterioration. Particu- lar attention should be paid to examin- ing those hose surfaces nearest tohigh heat sources, such as the ex- haust manifold. Inspect the hose routing to assure that the hoses do not come in contact with any heat source, sharp edges or mov- ing component which might cause heatdamage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they aresecure, and that no leaks are present. Hoses should be replaced immedi- ately if there is any evidence of dete-rioration or damage. 6ZF060H1-A
o Air cleaner filter
A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed.
6ZF060J1-A
o Spark plugs
Make sure to install new spark plugs
of the correct heat range.
F060N02E-EAT
o Valve Clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces- sary. A qualified technician should perform the operation. 6ZF070B1-A
o Cooling system
Check the cooling system part, such
as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.
6ZF070C1-A
o Coolant
The coolant should be changed at
the intervals specified in the mainte-nance schedule.
6ZF070D1-A
