RC.600.274 12v dc air conditioner 977011D300 For COMPRESSOR KIA CERATO 1.6 2004-2008 WXKA001

Parameter :

Product Description

• Rapid Refrigeration: Thanks to its powerful and robust compressor, the cooling function operates quickly and steadily. It also excels in dissipating heat.
• Stable & Strong Pressure: The air-conditioning compressor is driven by a powerful motor, generating high pressure that is compressed and transmitted to achieve effective cooling.
• Energy Saving & Noise Reduction: The air conditioning compression system helps save fuel consumption, reducing overall fuel costs. Noise and vibration reduction greatly enhance the driving experience.
• Well Tested & Easy To Install: Comprehensive functional testing is conducted prior to delivery. The presence of sufficient frozen oil facilitates easy replacement. No welding, adjustments, or modifications are required.

How to Identify a Malfunctioning Automotive A/C Compressor

1.Inadequate Cooling Performance

• The most obvious sign is when the air conditioning system fails to produce cold air or takes significantly longer to cool the cabin than usual. This could indicate the compressor isn't properly compressing refrigerant.

2.Unusual Noises

• Listen for abnormal sounds when the A/C is engaged:
• Loud grinding or rattling noises suggest internal component damage
• Squealing sounds may indicate a failing clutch or belt issue
• Clicking noises when cycling on/off could signal electrical problems

3.Visual Leaks

• Inspect the compressor and surrounding components for:
• Oil stains or wet spots (refrigerant oil leaks)
• Greenish UV dye (if system has been serviced previously)
• Corrosion or physical damage to compressor housing

4.Clutch Engagement Issues

• With the engine running and A/C on maximum:
• The center of the compressor pulley should engage and spin
• Failure to engage suggests electrical or clutch problems
• Intermittent engagement indicates low refrigerant or control issues

5.Excessive Vibration

• Noticeable shaking when the compressor is running may indicate:
• Internal component failure
• Imbalance in the rotating assembly
• Mounting bracket problems

6.Electrical Problems

• Check for:
• Blown fuses related to the A/C system
• Corroded or loose wiring connections
• Proper voltage at the clutch coil (typically 12-14V when engaged)

7.System Pressure Abnormalities

• Professional diagnosis should include:
• Static pressure tests (engine off)
• Running pressure tests (engine on, A/C operating)
• Comparison of high and low side pressures to specifications
