There are several reasons for abnormal noise when accelerating with the air conditioning on: 1. Belt Tension: The air conditioning belt may not be tight enough, causing it to slip. When you press the accelerator, the slipping belt produces abnormal noise. You can check the belt tension. 2. Voltage and Dirt: The electromagnetic clutch inside the compressor may slip due to insufficient circuit voltage or surface dirt and sludge. 3. Compressor Damage or Malfunction: The car's air conditioning compressor is the heart of the entire system. If the compressor has issues, it can cause corresponding faults. 4. Bearing Failure: A faulty tension bearing on the compressor's drive belt can also produce abnormal noise.

Is the Corolla the 86?

AE86 is a model from the compact car series of the Toyota Corolla. AE86 is not a name but merely a chassis code. The AE86 refers to the fifth-generation Corolla first produced in 1983. Previous models included the TE27, TE51, TE55, TE61, TE65, and TE71, followed by the AE86 chassis. This chassis was not only used in the Corolla but also in the Trueno, hence the distinction between fixed-headlight and retractable-headlight AE86 variants. The AE86 marked the final FR (front-engine, rear-wheel-drive) model in the Toyota Corolla lineup, as the current Toyota 86 shares nothing with the AE86 beyond the '86' designation.

Can You Release the Clutch After Starting the Engine?

Manual transmission vehicles can be started in neutral without pressing the clutch. Below are detailed explanations: Explanation: Pressing the clutch when starting the engine reduces the load on the starter motor and allows the ignition system to deliver more electrical power, ensuring a good starting condition for the engine. If the clutch is not pressed during ignition, it increases the load on the starter motor, causing the battery to output a higher current, which affects the engine's ignition performance. Additional Information: For European and American imported vehicles, the ignition circuit cannot be engaged without pressing the clutch. American cars are particularly strict about this, with Ford models being a standard example—they cannot be started without pressing the clutch.
