What is the idle speed of an automatic transmission car?

Under normal conditions, the idle speed of an automatic transmission car is 700-800 RPM. Below are the specific details about car idle speed: 1. High idle speed: The hazards of high idle speed include increased fuel consumption, elevated engine operating temperature, and accelerated machine wear. 2. Low idle speed: The hazards of low idle speed include stalling during startup, which can damage the engine and starter if frequently restarted. Additionally, excessively low idle speed may lead to stalling while driving, and long-term operation can cause carbon buildup in the engine cylinders, resulting in weak acceleration. 3. Prerequisites for idle speed adjustment: The engine temperature must be normal, valve clearance appropriate, ignition system functioning properly, all pipelines well-sealed, choke fully open, and throttle able to close tightly.

How many liters of coolant does a Prado require?

Prado requires approximately 7 liters of coolant. Generally, the coolant reservoir has a max and min level mark, and the coolant should be filled between these two marks. For most family cars, the coolant replacement requires 4-6 liters, depending on the vehicle. Methods to determine if coolant is insufficient: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to insufficient coolant, though it could also be caused by excessively high engine temperature. Check the coolant reservoir. If the level is below the minimum mark (MIN), do not continue driving and add coolant promptly. Check the water level marks on the coolant reservoir. The normal coolant level should be between the max and min marks. Whether the coolant is insufficient depends on the marks. If the coolant is below the minimum mark, it indicates a shortage.

What to Do When the Car Steering Wheel Becomes Heavy?

Solutions for a heavy car steering wheel are as follows: 1. If the steering wheel becomes heavy while driving, slow down, pull over promptly, and check for oil pipe leaks. 2. Inspect the vehicle's tire pressure. Low tire pressure can make the steering wheel heavy, and air leaks can also cause this issue. Inflate the tires if necessary. 3. If there is excessive play in the front suspension system, replace the lower control arm after inspection. 4. Check if the power steering pump belt is too loose. Tighten the belt if it is loose. Also, check if the fluid is too dirty, which can impair flow. Typically, replace the fluid every 2 years or 60,000 kilometers.

What to Pay Attention to When Entering a Gas Station?

Things to note when entering a gas station: 1. Follow the road to enter the gas station; do not park at the gas station entrance.
