How many cylinders does the Envision have?

Where is the OBD port located in the car?

The OBD port in a car is generally located below the left side of the dashboard. The exact position may vary depending on the vehicle model—some are above the accelerator pedal, while others are in front of the gear lever. The OBD port is a 16-pin female connector with a trapezoidal shape. Some vehicle models have a protective cover over the OBD port, and the common colors for the port are black, white, or blue. OBD refers to the On-Board Diagnostics system, which monitors the engine control system and other functional modules of the vehicle in real-time during operation. If any abnormal conditions are detected, the system can identify specific faults based on predefined algorithms and store them as diagnostic trouble codes in the system's memory.

Do Tires Have a Right Side and a Wrong Side?

Tires do have a right side and a wrong side. There is a numerical mark on the side of the tire that can help determine the correct orientation. When installing the tire, ensure the side with the number faces the front of the wheel hub. The following points should be noted when replacing tires: 1. For unidirectional tires, first consider the specific position where the tire and rim combination will be installed on the vehicle. Then, according to the rotation arrow indicated on the tire sidewall, mount the tire onto the rim. After the tire and rim combination is installed on the vehicle, check to ensure that the rotation arrow on the tire sidewall aligns with the forward direction of the vehicle. 2. For asymmetric tread tires, when mounting the tire onto the rim, pay attention to ensure that the side of the tire marked with 'outside' in English faces outward.

How Many Liters of Antifreeze Are Needed?

Changing the antifreeze requires 6 to 7 liters, which generally applies to newly assembled vehicles. For vehicles that are drained and refilled, it typically requires 5 to 6 liters. The specific details are as follows: 1. Both scenarios require adding the antifreeze in two stages. The first stage is when the vehicle is static—add while squeezing the rubber hose by hand until the fluid level is between 'low' and 'high.' 2. The second stage is after the vehicle has been driven for a certain distance. Observe if there are any signs of the coolant level dropping. If so, stop the vehicle and wait for the engine to cool before adding more until it reaches the same level as the first stage. 3. Antifreeze, also known as coolant, is designed to prevent freezing. It prevents the coolant from freezing in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Many people think antifreeze is only used in winter, but it is actually required year-round. 4. Different manufacturers use different additives in their antifreeze. Mixing them may cause chemical reactions that could damage the cooling system. It is best to drain all the old antifreeze before adding new antifreeze.

Why Does a Diesel Engine Shake at Idle?

Here are the reasons why a diesel engine shakes at idle: 1. Stuck fuel injector: A stuck or poorly atomizing injector in one cylinder causes that cylinder to not work or work poorly (blue-white smoke may be emitted from the exhaust). This can be checked using the cylinder cut-off method. 2. Uneven fuel supply from the injection pump: Uneven idle fuel supply from the injection pump leads to inconsistent cylinder operation at idle. 3. Low RPM: Improper idle adjustment (too low RPM) can be resolved by adjusting the idle fuel supply screw. 4. Improper valve clearance: Incorrect valve clearance (due to loose adjustment screws, abnormal wear, or abnormal wear of the valve pushrod) causes the cylinder to not work or work poorly. This can be fixed by adjusting the valve clearance. 5. Poor valve sealing, leading to suboptimal operation. 6. Engine overheating or insufficient oil (causing poor lubrication), making it difficult for engine components to operate smoothly.

Which switch is used for windshield defogging?

Windshield defogging is activated by pressing the defogger switch. Other methods for windshield defogging include: 1. Wiping it clean with a towel. 2. Turning on the car's heater to clear the fog. 3. Leaving a slight gap in the window to remove fog. 4. Using an automotive glass anti-fog spray. Here is some related information: 1. Reasons for windshield fogging are as follows: (1) Temperature difference between the inside and outside of the car. (2) The window temperature is lower than the outdoor temperature. (3) Temperature difference between the two sides of the window. 2. Methods for maintaining the glass include: (1) Using appropriate windshield washer fluid according to the season. (2) Applying automotive glass heat insulation film. 3. Functions of the glass include: blocking wind and rain, noise reduction and sound insulation, reducing wind resistance and guiding airflow, and protecting the safety of passengers.

Does a manual transmission need gearbox oil change?

New cars do not require it. If the driving time exceeds two years or the mileage exceeds 60,000 kilometers, the gearbox oil should be changed regularly. Expired or deteriorated gearbox oil can cause difficulty in shifting gears and wear on the transmission bearings. Below is relevant information about gearbox oil: 1. The main function of gearbox oil is to keep the shifting system clean and to lubricate and prolong the life of the transmission components. Due to differences in transmission design, gearboxes are divided into manual transmissions and automatic transmissions (further categorized into CVT, AMT, etc.). Each transmission design has different technical requirements. Even the same model of transmission configured in different vehicle models will have variations in torque, weight, speed, and structure. Therefore, the original manufacturer specifies its own dedicated gearbox oil. 2. Generally, an automatic transmission in a car requires an automatic transmission oil change every two years or every 40,000 kilometers. This varies depending on the vehicle model. For Japanese models, it is recommended to change the oil every 40,000 to 80,000 kilometers. Vehicles that frequently drive at high speeds are advised to change the oil approximately every 40,000 kilometers.
