What type of engine oil does the Toyota Sienna use?

How many kilometers should the car gearbox oil be changed?

Generally, for fuel-powered vehicles with automatic transmissions, it is recommended to change the transmission oil every 2 years or after driving more than 40,000 kilometers; for manual transmissions, it is usually recommended to change the transmission oil every 3 years or after driving more than 100,000 kilometers. Additional information about gearbox oil: 1. Introduction: Gearbox oil, also known as automotive gear oil, is a high-viscosity lubricant primarily composed of petroleum-based lubricating oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil. 2. Function: It is used in various gear transmission devices to prevent tooth surface wear, scuffing, sintering, etc., thereby extending their service life and improving power transmission efficiency. Vehicle gear oil is classified by performance and viscosity.

Can a Car Still Be Driven with an Engine Misfire?

If too many cylinders in the engine are misfiring or two adjacent working cylinders misfire simultaneously, the vehicle cannot be driven and may even fail to start. However, if only one cylinder fails to ignite, the car can still continue to operate. When engine misfire issues occur, it is recommended that owners promptly take their vehicle to a repair shop for inspection. Below are relevant details: 1. Overview: Engine misfire refers to the phenomenon where one or more cylinders fail to ignite properly, resulting in incomplete combustion within the engine's combustion chamber. 2. Causes of Engine Misfire: There are multiple reasons for engine misfires, with common faults including malfunctioning ignition coils, aged or failed spark plugs, clogged fuel injectors, insufficient fuel pump pressure, and excessively high or low air-fuel mixture concentration. Regularly cleaning engine carbon deposits can also effectively prevent misfire issues.

How much over the speed limit is allowed in section speed measurement without penalty points?

On highways or national roads, exceeding the speed limit by less than 10% only results in a warning, without penalty points or fines. Here are the relevant details: 1. Section Speed Measurement: This involves setting up two adjacent monitoring points on the same road section. The principle is to calculate the average speed of a vehicle over that section based on the time it takes to pass between the two monitoring points, and then determine if the vehicle has exceeded the speed limit according to the set standard for that section. 2. Additional Information: Traffic regulations, officially known as the Road Traffic Safety Law of the People's Republic of China, are established to maintain road traffic order, prevent and reduce traffic accidents, protect personal safety, safeguard the property and other legal rights of citizens, legal persons, and other organizations, and improve road traffic efficiency.

What are the functions of the two fans in a car?

One is the radiator cooling fan (to help cool the engine), and the other is the air conditioning cooling fan. Here is additional information: 1. Fan installation location: The fan is installed behind the radiator and shares the same axis as the water pump. When the fan rotates, it creates suction on the air, accelerating the airflow along the axial direction, thereby speeding up the cooling of the coolant flowing through the radiator core. At the same time, it cools the engine body's shell and surrounding components. 2. Fan function: The car fan blows towards the radiator to cool it down, generally blowing forward to dissipate heat from the engine. It should not blow towards the engine direction, as this would increase the engine's temperature.

What Causes a Car to Pop Out of Gear?

Causes of gear popping out include malfunctions in the gear shift control mechanism, wear in the reverse gear locking mechanism inside the transmission, and abnormal wear of the inertia lock ring or synchronizer. If a car's transmission experiences gear popping out, immediate repair is necessary, as it can affect the vehicle's normal operation. Automatic transmissions do not experience gear popping out issues. Below is additional information: 1. CVT Transmission: A CVT transmission is a relatively simple automatic transmission with only two cone pulleys and a steel belt inside. The steel belt in a CVT can move along the cone pulleys. 2. AT Transmission: The AT transmission is the most mature and widely used automatic transmission, also known as a torque converter transmission. This type of transmission connects to the engine via a torque converter.

Where Does Water Enter a Car?

Car can actually take in water from the air intake, which is the inlet of the air filter. All the plastic pipes from the air intake to the throttle must be well sealed to prevent water from entering the engine. Here are some related introductions: 1. Engine stalling due to water ingress: When the engine stalls due to water ingress, do not attempt to start it again immediately. Under such circumstances, it's impossible to immediately determine the cause of the stalling. Acting rashly may cause unpredictable greater damage to the vehicle. The best course of action is to manually push the vehicle to a safe location and then call for assistance. 2. Inspection method: The simplest method is to check if the color of the engine oil is abnormal. If the engine oil turns milky white, it indicates that water has entered the fuel tank or the engine.
