Can Coolants of Different Colors Be Mixed Together?

Coolants of different colors may vary in chemical properties and compositions. Even if their primary ingredients are the same, their secondary components and formulation ratios can differ. In other words, coolants of different colors should not be mixed. Combining multiple chemical components may trigger reactions, causing the coolant to lose its original properties. 1. Coolant Composition: There are three types of coolants based on their main ingredients—ethylene glycol, propylene glycol, and glycerin (glycerol). Currently, most coolants on the market are ethylene glycol-based. To distinguish coolants from other liquids and to indicate their toxicity, dyes are added, resulting in coolants of various colors such as green, red, and blue. 2. Handling Mixed Coolants: If coolants are accidentally mixed, drain the coolant from the radiator, rinse it thoroughly with clean water, and then refill with new coolant. Most vehicle radiators have a drain valve at the bottom of the radiator's backside, usually black—simply unscrew it to drain. However, never remove the radiator cap when the engine is hot, as high-pressure coolant may spray out, potentially causing severe burns.

What Does Transit Vehicle Mean?

A vehicle from another region passing through the local area is called a transit vehicle. Below is relevant information: 1. Transit Vehicle: Local traffic authorities often impose restrictions on the routes and times for transit vehicles to ensure smooth traffic flow in their jurisdiction. A vehicle from another region passing through the local area is called a transit vehicle. For example, a vehicle traveling from Beijing to Guangdong Province that passes through Nanjing would be considered a transit vehicle for Nanjing. To ensure smooth urban traffic, traffic authorities frequently restrict the routes and times for transit vehicles. 2. Transit Transportation: Transit transportation refers to the movement of passengers or goods from one country through the territory of another country to a third country. International transport agreements typically include clauses on transit transportation, specifying transit fares, procedures, and other details. Countries that are parties to these agreements can conduct transit transportation in accordance with the agreed terms.

Does replacing a car door have a big impact?

Replacing a car door has little impact on the vehicle, as long as the door is installed correctly and does not affect the normal use of the car. Unless the car door is severely damaged and needs replacement, minor scratches or dents do not warrant a door replacement. The cost of replacing an original car door is very high, so it is essential to drive according to traffic regulations in daily use to avoid damage to the car. Car doors can be classified by opening methods: 1. Front-hinged doors: Commonly used in family cars. 2. Rear-hinged doors: Mainly used in limousines and luxury vehicles. 3. Sliding doors: Their advantage is that they can fully open even when the distance between the car body and obstacles is small. 4. Gull-wing doors: Mostly used in sports cars. 5. Folding doors: Widely used in large and medium-sized buses.

Where to Apply for ETC?

ETC can be applied for at bank branches, expressway service areas, and other authorized institutions. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the owner, the agent must also bring their valid ID card. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. Additionally, a Postal Savings credit card application form is required, as the credit card will be used to bind the ETC card. After obtaining the credit card, swipe it twice and present the POS receipt to the designated Postal Savings outlet to receive and install the ETC onboard device for free, with no additional charges. Applicants must be between 18 and 60 years old and own a vehicle registered under their name. ETC stands for Electronic-Toll-Collection, which refers to the electronic toll collection system. To apply, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle license. If the application is not made by the owner, the agent must also bring their valid ID card. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. A bank card for deducting expressway toll fees is also required. Applicants must be between 18 and 60 years old and own a vehicle registered under their name. Here are some important notes for installing ETC: Do not obstruct the driver's view; it is best to install it behind the rearview mirror: Many car models have a steeply angled windshield, which can reduce the driver's field of vision. Installing the ETC without considering this may increase blind spots. Install it on the right side behind the rearview mirror to avoid obstructing the view. Avoid affecting charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. After installation, the windshield will press the lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid paying for the vehicle in front due to its ETC device malfunction, maintain a distance of more than 10 meters. The ETC lane recognizes vehicles at a speed of 20 km/h; driving too fast may result in failure to read the device information and toll deduction failure. If using a debit card to bind ETC, insufficient balance may also cause toll deduction failure.

Is it safe to keep the cigarette lighter plugged in all the time?

It is not safe to keep the cigarette lighter plugged in all the time. Generally, the cigarette lighter will automatically pop out after reaching a certain temperature, which will not harm the vehicle. However, if the pop-up mechanism is damaged, it will continue to heat up until it damages the vehicle or runs out of power. Functions of the cigarette lighter: 1. Lighting cigarettes: It allows people in the car to light cigarettes even if they don't have a lighter. 2. Charging devices: Car air pumps and air purifiers can be charged using the DC power from the cigarette lighter. 3. Installing a charging frequency conversion fuel saver: The most concerning issue when driving is fuel consumption, as a car cannot run without fuel. Many people want to reduce their vehicle's fuel consumption. By plugging a universal charging frequency conversion fuel saver into the cigarette lighter, it can not only reduce fuel consumption in stop-and-go traffic but also clearly display the fuel consumption amount. Additionally, it can alert the driver when the vehicle is running low on fuel.

What should I do if I accidentally filled up with 92 octane gasoline instead of 95?

If your car originally used 95 octane gasoline and you accidentally filled it with 92 octane, there generally won't be any significant impact. Here is some relevant information about automotive gasoline: 1. Gasoline octane rating: The octane rating primarily indicates the ratio of a gasoline's anti-knock properties compared to standard gasoline (knock resistance). Standard gasoline consists of isooctane and n-heptane. The higher the octane rating, the stronger the anti-knock performance. 2. The difference between 95 and 92 octane gasoline: 95 octane gasoline contains 95% isooctane, with the remaining 5% being n-heptane. The higher the proportion of isooctane, the better the gasoline's anti-knock capability. In other words, 92 octane gasoline is more prone to knocking but has less explosive force, while 95 octane gasoline is less prone to knocking but has greater explosive force.
