Is It Necessary to Turn Off the Air Conditioner Before Parking?

[McBrianna]

It is necessary to turn off the air conditioner before parking. Turning off the engine before the air conditioner can be harmful to the engine because, during the next vehicle start-up, the engine will start with the air conditioner's load, which can cause damage due to the high load. The reasons for engine jerking are as follows: 1. High engine idle speed. 2. Improper adjustment of the throttle cable or throttle position sensor, leading to excessively high main oil circuit pressure. 3. Delayed upshift. 4. Cracked or loose vacuum hose of the vacuum-type throttle valve. 5. Malfunction of the main oil circuit pressure regulator, causing excessively high main oil circuit pressure. 6. Stuck damper piston, failing to provide damping. 7. Missing one-way valve steel ball, causing the shift actuator (clutch or brake) to engage too quickly. 8. Slipping of the shift actuator. 9. Non-functioning oil pressure solenoid valve. 10. Faulty computer.
