Features & Details
【PREMIUM ALUMINUM MATERIAL】- This ac air compressor is a replacement compressor and clutch. Its main body is made of high-strength aluminum material, which is durable, rigid, and wearable. It will not crack, break, or leak. Such high-quality ensures a long-time use of each compressor kit.
【STRONG COOLING FUNCTION】- The auto ac compressor can provide sufficient pressure, which increases power force and decreases engine load. It dramatically improves the cooling function: features as high and stable efficiency, safety, and reliability.
【LOW NOISE & FUEL CONSUMPTION】- The AC compressor works steady and efficient under a low noise condition, provide you with a chill nice and cold ride. Under a lower load factor, low power will be input when driving at high speed, which increases fuel economy and makes operation smoothly.
【FULLY TESTED & EASY INSTALLATION】- The ac compressor clutch has been examined and tested carefully before its delivery. And the kit without refrigeration oil inside, be aware of it when starting your installation and replacement.
Note:
The compressor may contain PAG oil for lubrication during shipping; please drain and replace.
It is necessary to add an appropriate amount of oil and refrigerant (70-80%) to the ac compressor before use.
Please check the compatibility to make sure this is the correct compressor for your vehicle!

Attentions:
1. Please make sure the power has been cut off before repair or service the machine; in the meantime, the engineer should push a warning sign to avoid hurting someone else.
2. Shutdown maintenance must wait for the whole A/C compressor cooling down, and the compressed air is safely released. The maintainer needs to avoid any vent closing their relevant isolating valve as much as possible.
3. Adopted no-corrosive safety solvent to clean out the component is essential. Flammable, explosive, and volatile detergent is banned.
4. Please examine the protective system regularly to ensure sensitivity and reliability once a year is appropriate.
5. The A/C system must be flushed with approved flushing solutions by using the proper method. (Solvents and alcohol-based flushes are not supported.)

6.Diode installation at terminals may be required on below models:
For 2007 2009 2010 2011 2012 GL450 4.7L
7.During compressor installation, the pipelines must be thoroughly cleaned first. Failure to do so may cause cylinder scoring and render the product unusable.
