Installation Method

Attention Please:

Be sure to clean the air conditioning system before installation, otherwise it will cause compression broken.

1. Remove compressor:

Remove the A/C belt from the A/C compressor pulley. May involve loosening the belt tensioner (if equipped).

2.receiver drier or accumulator, orifice tube or expansion valve.

3.Disconnect the negative battery cable.

4.Remove the bolt that secures refrigerant lines to the A/C compressor. Inspect A/C lines for any contamination such as metal or excessive dirt inside of them. If you find any

contamination the system will need to be cleaned.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.

5.Drain all the oil from the new compressor ,if you compressor has a drain plug you will need to open it up and drain what oil is in there too.

6.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.

7.Install new receiver drier or accumulator and new orifice tube or expansion valve.

8.Evacuate the A/C system for a minimum of one hour.

9.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.

10.Turn on the A/C system with the engine running and check to see if cold air is now coming out of the air duct.

11.If the A/C system is functioning ,you may find that your electric radiator fan and compressor clutch will be cycling off and on depending on the outside air temperature.
