Yes. Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5%, using ultrapure water as the solvent. The raw materials are specialized automotive urea materials and ultrapure water. Automotive urea is highly soluble in water—105 grams can dissolve in 100 milliliters of water at 20°C, resulting in a neutral solution. Therefore, automotive urea solution barrels can be thoroughly cleaned with water, and once cleaned, they can be used to store water. Below is some relevant information about automotive urea solution: 1. Production Method: Industrially, urea is synthesized directly from liquid ammonia and carbon dioxide under high temperature and pressure. 2. Precautions: Automotive urea solution is non-toxic, but if the barrel is not thoroughly cleaned, long-term consumption of drinking water stored in such a barrel may cause gastrointestinal discomfort.

What are the rules for the combination of arrow lights and round lights?

Here is a detailed introduction to the rules for the combination of arrow lights and round lights: 1. Arrow signal lights: The direction of the arrow pointing left, up, or right indicates left turn, straight, or right turn, respectively. When the green arrow light is on, vehicles are permitted to proceed in the direction indicated by the arrow. When the red arrow light is on, vehicles are prohibited from proceeding in the direction indicated by the arrow. 2. Round signal lights: When the red light is on, right-turning vehicles may proceed if they do not hinder the passage of released vehicles and pedestrians. When the green light is on, vehicles are permitted to proceed, but turning vehicles must not hinder the passage of released straight-moving vehicles and pedestrians. When there are directional signal lights, vehicles should follow the rules of the directional signal lights. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed.

Where is the rearview mirror adjustment button?

The rearview mirror adjustment button is located on the left door. L represents the left rearview mirror, and R represents the right rearview mirror. Below are the adjustment methods for rearview mirrors during normal driving: 1. Interior rearview mirror: The main function of the interior rearview mirror is to see the situation of the vehicles behind. It needs to be adjusted to the angle that provides the maximum rear view range. Adjust the four corners of the interior rearview mirror to see the four corners of the rear windshield, which represents the maximum viewing angle. 2. Two exterior rearview mirrors: First, adjust the tilt angle of the rearview mirror so that the car body occupies one-fourth of the mirror. Then adjust the elevation angle of the rearview mirror. The left rearview mirror should be adjusted so that the sky and ground each occupy half of the mirror, with the center line being the central line of the rearview mirror. Due to the driver's position, the right rearview mirror should be adjusted so that the sky occupies two-thirds and the ground occupies one-third of the mirror.

Why does the old Jetta's water temperature rise when the AC is on?

If the water temperature remains normal during driving and when the AC is off, but rises only when idling with the AC on, it is a typical sign of a malfunctioning radiator fan for the AC evaporator. Below is relevant information about radiator fans: Axial Fan: An axial fan's blades push air to flow in the same direction as the axis. The impeller of an axial fan is somewhat similar to a propeller. During operation, most of the airflow moves parallel to the axis, meaning it flows along the axial direction. The power consumption of an axial fan is lowest when the inlet airflow is free air at 0 static pressure. As the back pressure of the airflow increases during operation, the power consumption also rises. Centrifugal Fan: When a centrifugal fan operates, its blades push air to flow in a direction perpendicular to the axis (i.e., radially). The intake is along the axial direction, while the exhaust is perpendicular to the axis. In most cases, an axial fan can achieve sufficient cooling. However, if the airflow needs to rotate 90 degrees for exhaust or higher air pressure is required, a centrifugal fan must be used. Strictly speaking, blowers also fall under the category of centrifugal fans.

Is transferring a car to my wife considered a used car transaction?

Transferring a car under the husband's name to the wife legally classifies the vehicle as a used car. Vehicle transfer between spouses is referred to as a "name change," which only alters the registered owner's name and has no impact on the vehicle's insurance or market value. Vehicle transfer between spouses requires license plate replacement. This process is identical to standard individual vehicle transfers, requiring the registration certificate, vehicle license, both parties' ID cards, and physical presence at the vehicle registration service station. Vehicle transfer between spouses without license plate replacement is a special case applicable only to married couples. Both parties must bring their marriage certificate, ID cards, registration certificate, and vehicle license to the DMV for modification procedures. If not changing the license plate number, simply submit an owner change application and take a new photo of the vehicle (at the DMV). Provide both spouses' ID cards and marriage certificate, with copies for record-keeping. Post-divorce vehicle transfer. After divorce, the spousal relationship no longer exists, making the transfer process identical to standard individual transfers. License plate replacement is mandatory in such cases, and while divorce certificates aren't required, both parties must bring vehicle documents and ID cards to the DMV. Required materials for transferring a vehicle to one's wife at the DMV: "Motor Vehicle Change Registration/Record Application Form", identification documents for both spouses (local residents provide ID cards, temporary residents additionally provide residence permits), original vehicle registration certificate, vehicle license, and proof of marital relationship (household register or marriage certificate). For used car transfers, the original owner must provide: registration certificate, vehicle license, and ID card. The buyer needs an ID card, with temporary residents requiring residence permits. Vehicle transfer first requires valuation, with assessment fees typically 1%-2% of the appraised value, plus license plate and documentation fees. Original commercial insurance can be canceled (compulsory insurance cannot), or transferred to the new owner through the insurance company. Used car purchase considerations: Incomplete documentation. Complete used car documentation includes: vehicle registration certificate (or original purchase invoice), vehicle license, vehicle purchase tax certificate, road maintenance fee records, and compulsory insurance. Missing documents or unpaid fees create significant complications for buyers. Odometer tampering. Many buyers rely on mileage to assess condition, which sellers may manipulate. Mileage serves not just as usage indicator but as maintenance records. Following falsified mileage for maintenance creates safety hazards. New paint concealing damage. When selecting used cars, fresh paint on the front, rear, or around structural pillars may indicate major accident history. Engine refurbishment inflating value. Many buyers focus excessively on engine condition while neglecting body integrity. Sellers may replace engine components to make the "heart" appear younger and justify higher prices.

Can the vehicle owner be changed?

The vehicle owner can be changed, but changing to someone else's name involves a transfer of ownership, which requires re-registration. Below is some information about vehicle ownership transfer: Introduction: Vehicle ownership transfer refers to changing the name of the vehicle's owner. When buying a used car, besides checking the car's condition, the most important step is completing the ownership transfer process. Principle: Every vehicle has a fixed registration record, which primarily includes the owner's name and address, as well as relevant vehicle parameters. If a vehicle has issues, such as involvement in an accident, failure to pass annual inspection, being stolen, or being smuggled, the ownership transfer cannot proceed through normal procedures.
