What Does an AC Compressor Do?

The air conditioning compressor is the heart of the AC system.

Its responsibilities include:

• Compressing refrigerant
• Circulating refrigerant through the system
• Creating cooling pressure
• Supporting cabin temperature control

Without a functioning compressor, even a fully charged AC system cannot produce cold air.

Common Signs of a Bad RSX AC Compressor

Many RSX owners notice symptoms long before complete compressor failure occurs.

Warm Air from Vents

The most common sign of compressor failure.

Compressor Clutch Not Engaging

The AC system may fail to activate.

Grinding or Squealing Noises

Internal compressor damage often creates unusual sounds.

Refrigerant Leaks

Seal failures can cause refrigerant loss.

Intermittent Cooling

Cold air may come and go unpredictably.

If these symptoms appear, the compressor should be inspected before further damage occurs.

Direct Replacement Design

The ECCPP compressor is engineered to function as a direct replacement for factory-equipped units.

Compressor Specifications

• Compressor Type: HS090R
• Oil Type: PAG46
• Pulley Grooves: 7
• Pulley Diameter: 100mm
• Internal Oil Capacity: 130ml

These specifications closely match OEM requirements for compatible applications.

Includes Compressor and Clutch

One advantage of this unit is that it arrives with the clutch assembly already installed.

Package Contents

• AC Compressor
• Compressor Clutch Assembly

This simplifies installation and eliminates the need to transfer clutch components from the original compressor.

Pre-Filled with Oil

The compressor arrives pre-filled with PAG46 oil.

Benefits include:

• Simplified installation
• Reduced setup time
• Factory-prepared lubrication

The manufacturer advises against adding additional oil during installation unless system requirements specifically call for it.

Overfilling can reduce cooling performance and potentially damage the compressor.

Aluminum Construction

The compressor housing utilizes aluminum construction.

Advantages include:

Strength

Designed to withstand long-term use.

Corrosion Resistance

Better suited for harsh environments.

Weight Reduction

Lighter than many older compressor designs.

Heat Management

Aluminum helps dissipate heat more effectively.

Pressure Tested for Quality

According to the manufacturer, each compressor undergoes:

Nitrogen Leak Testing

This process helps verify:

• Seal integrity
• Leak resistance
• Proper assembly

Leak testing is an important step because refrigerant leaks are among the most common causes of AC system failures.

Why System Flushing Matters

One of the most overlooked steps during compressor replacement is flushing the AC system.

When a compressor fails, it can release:

• Metal shavings
• Debris
• Contaminated oil

Installing a new compressor without cleaning the system can result in premature failure.

Recommended Service Items

• AC system flush
• Receiver/drier replacement
• Expansion valve inspection
• Refrigerant recharge

Skipping these steps can shorten compressor lifespan significantly.

Cooling Performance

The manufacturer highlights:

• Low vibration operation
• Reduced noise levels
• Strong cooling performance

A properly functioning compressor can restore comfortable cabin temperatures even during hot summer conditions.
