What you need to know
If you’re replacing an A/C Compressor, you have to be prepared to replace additional components in the system depending on the reason why your own
compressor failed. The information provided below was made to help you save TIME and MONEY.
1.) Compressor locked/seized internally:
If your compressor seized internally it was due to insufficient refrigerant or oil in the system or the system was
blocked, leading to overheating of the compressor which caused a breakdown of internal parts.
The oil in the compressor is black and/or has aluminum particles in it. The belt snapped or when the a/c is
turned on, the engine feels like it’s going to turn off.
What you should do:
1. Replace the A/C Compressor (make sure to add PAG Oil)
2. Replace the Receiver Drier/Accumulator
3. Replace the Expansion Valve/Orifice tube
4. Flushing the a/c lines, condenser and evaporator is REQUIRED (We professionally recommend to replace
the condenser on modern vehicles since the passage on the fins are so small that a flush will not remove all
5. Vacuum the system for 30 – 45 minutes. This will remove any moisture in the system.
6. Add the correct amount of refrigerant to the system.
7. Run vehicle on lowest fan setting for about 3 minutes to allow the compressor to cycle the refrigerant and oil.
The reason why it’s important to replace the additional parts listed is because if you add a
new compressor to acontaminated system, the compressor will cycle the contaminants and will eventually lock up again
1) Rotary Vane - Panasonic
Rotary vane compressors consist of a rotor with three or four vanes and a carefully shaped
rotor housing. As the compressor shaft rotates, the vanes and housing form chambers.
The R134a is drawn through the suction port into these chambers, which become smaller as
the rotor turns. The discharge port is located at the point where the gas is fully compressed.
The vanes are sealed against the rotor housing by centrifugal force and lubricating oil. The
oil sump and oil pump are located on the discharge side, so that the high pressure forces oil
through the oil pump and then onto the base of the vanes keeping them sealed against the
During idle an occasional vane noise from the compressor may be heard. This is due to the
time taken for lubricating oil to circulate through the A/C system.
2)Scroll type - Sanden
This compressor uses a unique design with two scrolls, one fixed and one is movable, both are inter-leaved.
The movable spiral is able to ORBIT or oscillate without actually fully rotating. The movable scroll is connected
to the input shaft via a concentric bearing.
As the movable spiral oscillates within the fixed spiral, a number of pockets are formed between the spiral. As
these pockets decrease in size the refrigerant is squeezed, the pressure increases and is discharged
through a reed valve at the discharge port in the rear section of the compressor.
3)Variable stroke - Harrison V5
The Delphi (Harrison) V5 compressor is a non-cycling variable displacement compressor.
The compressor varies displacement to control capacity to meet A/C system demand at all operating conditions. The compressor features a variable angle wobble plate in five (V5) cylinder axial piston design.
Displacement is controlled by a bellows actuated control valve located in the rear cylinder head. This control valve senses and responds to the system suction pressure or A/C system demand.
Through regulation of compressor crankcase pressure, the wobble plate angle, and therefore compressor displacement is variable.
In general, the compressor discharge pressure is much greater than the compressor crankcase. Which is greater than or equal to the compressor suction pressure.
At maximum displacement, compressor crankcase pressure is equal to the compressor suction pressure.
At reduced or minimum displacement, the compressor crankcase pressure is greater than the suction pressure.
Compressors and Mount & Drive:
Mount & Drive
Consists of a bracket to mount the compressor to the engine, a belt idler pulley, compressor
drive belt and possibly and extra drive pulley for the crankshaft.
Manufactured of either plate, cast iron, steel or aluminium, this bracket should exhibit
excellent noise absorption qualities especially if using a piston type compressor.
A small pulley normally used in conjunction with a belt adjusting mechanism, also used when
a belt has a long distance between pulleys to absorb belt vibrations.
Some vehicles do not have an extra pulley to accommodate an A/C drive belt, in these
cases an extra pulley is bolted onto the existing crankshaft pulley.
The clutch is designed to connect the rotor pulley to the compressor input shaft when the field coil is energized. The clutch is used to transmit the power from the engine crankshaft to the compressor by means of a drive belt.
When the clutch is not engaged the compressor shaft does not rotate and refrigerant does not circulate the rotor pulley free wheels. The field coil is actually an electromagnet, once energized it draws the pressure plate towards it, locking the rotor pulley and the pressure plate together causing the compressor internals to turn, creating pressure and circulating refrigerant.
Is the term used when enough heat is added to a liquid substance to change it into a vapor (gas). For example, when water is boiled.
This condition occurs within the A/C system.
The Condenser function is to act as a heat exchanger and allow heat to flow from the hot
refrigerant to the cooler outside air.
R134a entering the condenser will be a high-pressure high temperature vapor. As the R134a
vapor travels through the tubes of the condenser heat is given off to the cooler ambient air; the
refrigerant vapor condenses and changes to a liquid state.
At this point a large amount of heat is given off by the R134a. The refrigerant will now be a hot,
high pressure liquid.
This type of condenser consists of one long tube which is coiled over and back on itself with cooling fins in between the tubes.
2)Parallel flow design
(Recommended for R134a)
This design is very similar to a cross flow radiator. Instead of refrigerant travelling through one passage (like serpentine type), it can now travel across numerous passages. This will give larger surface area for the cooler ambient air to contact.
