AC Compressor 67671 Fit For NISSAN Maxima Murano Quest Pathfinder For INFINITI QX JX
Feature & Details：
【PREMIUM ALUMINUM MATERIAL】- This ac air compressor is a replacement Compressor and Clutch, 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 for each compressor kit.
【STRONG COOLING FUNCTION】- The auto ac compressor can provide sufficient pressure, which increases power force and decreases engine load. It greatly improves the cooling function. Features as high and stable efficiency, safety, and reliability.
【LOW NOISE & LOW FUEL CONSUMPTION】- AC compressor works great and has low noise for a better experience. With 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 start your installation and replacement.

Fitment：
- For NISSAN Maxima Murano Quest Pathfinder For INFINITI QX JX
Package Including：
1 x A/C Compressor
Installation Method：
- Remove compressor, receiver drier or accumulator, orifice tube or expansion valve.
- Flush the condenser and evaporator using NON-OIL BASED A/C flush. On expansion valve systems. The valve must be removed before the evaporator can be flushed. Flushed condensers from outlet to inlet and evaporators from inlet to outlet.
- Drain all the oil from the new compressor and dispose of according to local, state and federal laws. (NOTE: if your compressor has a drain plug, you will need to open it up and drain what oil is in there too.)
- Install half oil charge into the compressor and the remainder throughout the system. Turn compressor shaft 8-10 full revolutions to insure front seal and other internal parts are lubricated.
- Install new receiver drier or accumulator and new orifice tube or expansion valve.
- Evacuate the A/C system for a minimum of one hour.
- After evacuation install half the refrigerant charge and let the system set for 1 minute. This will allow the refrigerant to pick up oil and spread more evenly throughout the system.
- Start engine whit A/C controls on MAX AIR with door and windows open.
- Add the remaining charge of refrigerant as called for by the manufacture.
Automobile Air Compressor Installation Instruction:
I. The function of air compressor is to compress air, not to cool air. A product that has no signs of leakage, abnormal sound and has sufficient pressure can be certificated as a qualified product.
II. If the original automobile compressor is broken, it indicates the original automobile air conditioning system has already failed. The causes of the failure can be summarized as follows:
(1) Poor heat dissipation and too much fluoride will cause impressively high pressure, overwhelming the capacity of the compressor and causing components of the connection rod broken or burning lock;
(2)Because of too long vehicle service, the compressor is aging seriously and produces organic carbide ,which will impede water from being drained out by making the pipes blocked or the deliquefaction jar invalid, resulted in pipeline ice blockage;
(3)The installed pipe assembly isn't fixed properly, resulted in air leakage.
III. The following steps shall be followed before the replacement of the compressor:
(1) Clean all pipes of the air conditioning system individually, inject cleaning agent into the condenser and evaporator and soak them for about 20 minutes. Pour out the cleaning agent and dirt with high-pressure nitrogen. The deliquefaction jar, fluid collector and throttle shall not be cleaned; make sure that no residue of the cleaning agent remains in the system; desiccate the refrigerant circuit, if necessary;
(2)Clean the surface of the condenser and evaporator, check if the cooling fans' speed is normal;
(3)Clean or replace the expansion valve; the deliquefaction jar and pipe filter shall be replaced;
(4) Check and correct oil filling level and oil viscosity before installing the compressor; vacuumize, fill fluorine, check high pressure and low pressure. Usually, the normal ranges of high pressure and low pressure are 180-200Psi and 30-40Psi respectively. If the pressure is abnormal, diagnose and troubleshoot first before installing the compressor;
(5)Check and correct oil filling level and oil viscosity before installing the compressor.
Note:
If the original automobile compressor is jammed and shows cylinder scoring, make sure to clean the pipes and replace the heatsink net. Because the specific characteristics of the heat sink net, the above mentioned problems would produce Aluminum scrap, iron powder and residues that cannot be eliminated. Warranty will not be provided in case of the following circumstance: install the compressor without cleaning the pipes and replacing the heatsink net, which would cause cylinder scoring and lock of the newly installed compressor immediately.
