Auto ac compressor for benz w202

Types of Auto AC Compressor for Benz W202

The auto AC compressors for Benz W202 have different types. They include:

• 1. Scroll compressors

  These are a type of refrigeration compressor that use two spiral-shaped, non-overlapping scrolls that orbit each other to compress refrigerant vapor. One scroll acts as an inlet, and the other acts as an outlet. The orbiting scroll traps the refrigerant between the scrolls and moves it toward the center, where it is discharged. The design of scroll compressors results in smooth, quiet operation with high efficiency and reliability, making them ideal for AC.

• 2. Variable displacement compressors

  Variable displacement compressors automatically adjust their cooling output to match the temperature set on the thermostat, maintaining more precise temperature control and using less power. They achieve this by varying the stroke of the swashplate, which changes the amount of refrigerant cycled through the system. As a result, variable displacement compressors provide better energy efficiency and comfort.

• 3. Electric AC compressors

  These compressors are powered by the car's electrical system rather than the engine drive belt. This allows for more precise control of the cooling output, even when the engine is idle. Electric AC compressors enable better climate control and can improve fuel efficiency by reducing the load on the engine.

• 4. Belt-driven compressors

  Belt-driven compressors are the most common type of compressors used in vehicles. They are powered by the engine through a belt and pulley system. The belt-driven system is simple and reliable, but the compressor runs constantly while the engine is operating. Belt-driven compressors can be either fixed displacement or variable displacement, depending on the design.

Specification & Maintenance of Auto AC Compressor for Benz W202

Specification

The specifications for the AC compressor for the Benz W202 vary depending on the make and model. However, the general specifications remain as follows.

• Model Number

• Voltage

  The AC compressor uses a specific voltage to function. Compressors used in W202 models use a voltage of 12.

• Current

  The current rating for the compressor is also specified. The current rating indicates how much current the compressor draws while running. For the Benz W202, the current ranges from 4 to 10.

• Displacement

  The displacement measurement indicates the amount of air moved by the compressor in one rotation. It is measured in cubic centimeters (cc). The displacement for the W202 compressor ranges from 100 to 200 cc.

• Mounting

  The mounting for the compressor is also specified. The mounting indicates how the compressor is attached to the engine. For the W202, the compressors are mounted using bolts or brackets.

• Cooling

  The cooling type for the compressor is also specified. The compressor cooling type indicates how the compressor is cooled. For the W202, the compressor is either air or water cooled.

• Oil Type

  The type of oil used in the compressor is specified. The oil helps lubricate the moving parts of the compressor. The oil used in the W202 compressors is either mineral or synthetic oil.

Maintenance

Like any other mechanical part, the W202 AC compressors need to be maintained to improve their lifespan and efficiency. Here are some maintenance tips:

• Regular Inspection

  The first step while maintaining the W202 compressor is to inspect it regularly. During the inspection, check for signs of wear, damage, and leaks. Check whether the mounting bolts are loose. In case of any damage, the part should be replaced or repaired.

• Check and Replace the Drive Belt

  The drive belt is responsible for connecting the compressor to the engine. Check the belt regularly to ensure it is in good condition. Also, ensure the tension is at the required level. In case of any damage, replace the belt.

• Check the Oil Level and Quality

  The oil level in the compressor should be checked regularly. Ensure it is at the recommended level. The oil quality should also be inspected. In case the oil has degraded, replace it with a fresh one.

• Check the Refrigerant Level

  The refrigerant level should also be checked regularly. Ensure it is at the recommended level. In case the level is low, check for leaks and repair them.

• Clean the Compressor

  The W202 compressor should be cleaned regularly to prevent the build-up of dirt and debris. Use a soft cloth or brush to clean the compressor.

• Inspect and Replace the Electrical Components

  Check the electrical components like the wiring and switches. Inspect them for any damage or wear. Replace the components in case of any damage.

• Professional Maintenance

  In case of any major repairs or maintenance, take the car to a professional mechanic. The professional has the required tools and knowledge to handle major repairs.

How to choose auto AC compressor for Benz W202

Choosing the right AC compressor for a Mercedes Benz can be challenging because of the many options available. Here are some factors to help choose the right compressor:

• Model and make

  Choose the compressor that matches the make and model of the Mercedes Benz. This information can be found in the user manual or by contacting the dealership.

• Quality and warranty

  Choose a compressor from a reputable company. This ensures that the client gets a quality product. The compressor should also have a guarantee or warranty in case of failure.

• Price

  The price of the compressor should be within the set budget. However, it should not compromise quality.

• Professional advice

  If unsure of which compressor to choose, consult the mechanic. The mechanic can advise on the best compressor depending on the budget and needs.

How to DIY and replace Auto AC Compressor for Benz W202

It is important to note that before attempting to replace an AC compressor, make sure the R134a refrigerant has been recovered using an AC recovery machine. DIYers can follow the steps below to replace the compressor.

• Step 1: Locate the auto AC compressor on Benz W202.
• Step 2: Remove the serpentine belt from the AC compressor.
• Step 3: Disconnect the high-pressure and low-pressure AC lines from the compressor.
• Step 4: Use a wrench to remove the bolts that hold the compressor to the engine.
• Step 5: Remove the old compressor and install the new compressor by reversing the steps above.
• Step 6: Once the new compressor is mounted, fill the system with the recommended amount of engine oil.
• Step 7: Reconnect the AC lines to the compressor, ensuring a good seal to prevent leaks.
• Step 8: Reinstall the serpentine belt, making sure it is properly aligned on all pulleys.
• Step 9: Use an AC machine to recharge the system with the specified amount of R134a refrigerant.
• Step 10: Start the engine and run the AC to ensure proper cooling and check for any leaks or unusual noises.

Q and A

Q1: How long does an auto AC compressor for Benz W202 last?

A1: The AC compressor can last for 4 to 7 years. However, its lifespan can be shortened by factors such as frequent short trips, low refrigerant levels, and poor airflow.

Q2: What is the sign of a failing AC compressor?

A2: The compressor has a major role in the cooling process of the air conditioning system. Therefore, if the W202 has warm air blowing from the AC vents, it could be a sign of a failing compressor. Other signs include strange noises and visible leaks.

Q3: Can I drive with a failed AC compressor?

A3: The users can drive the W202 with a failed AC compressor. However, it is recommended to get it checked as soon as possible. This is because, aside from the discomfort caused by the warm air in the car, a faulty compressor can damage other components of the AC system.
