You can buy your own engine oil and go to a repair shop for maintenance. The main functions of engine oil are as follows: 1. Cleaning: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. 2. Rust and corrosion prevention: Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 3. Anti-wear: Adding a lubricant to friction surfaces can reduce the friction coefficient, thereby decreasing friction resistance, saving energy consumption, and reducing wear: the lubricant between friction surfaces can minimize wear caused by abrasive wear, surface fatigue, and adhesive wear.

Will There Be Any Impact If the Car Air Conditioning Pump Is Broken and Not Replaced?

Damage to the car air conditioning pump will affect the air conditioning system, leading to a loss of cooling function. This can result in issues such as damage to the air conditioning compressor. Damage to the air conditioning compressor can be categorized into two scenarios: first, electrical circuit damage, primarily involving damage to the compressor coil, open or short circuits in the motor coil, or insulation failure, all of which constitute motor damage. Second, mechanical failure of the compressor, mainly characterized by excessive noise, abnormal sounds, significant vibration, and a decline in the compressor's compression capability. If the compressor's compression capability declines, it is necessary to disassemble the compressor's exhaust pipe and intake pipe for diagnosis. Most standard compressors are of an integrated design and cannot be opened for repair; they must be replaced. Impact of a damaged car air conditioning pump: The air conditioning may stop working or exhibit poor cooling performance. Common symptoms include the compressor failing to rotate, unusual noises during operation, abnormal pressure levels (low high pressure or high low pressure), and damage to the exhaust valve. If the compressor's electromagnetic clutch coil burns out, generally, the compressor must be replaced, though the clutch coil can sometimes be replaced separately. A leaking shaft seal indicates compressor leakage, which might be caused by refrigerant contamination with water or oil seal damage, allowing non-compressible liquid to enter the compressor and damage the piston. Clutch damage can prevent the compressor from functioning. Once damaged, compressors are typically not repaired but replaced outright. It is advisable to use original equipment manufacturer (OEM) parts for replacement. A damaged air conditioning compressor can also impose unnecessary additional load on the engine.
