What are the effects of excessive coolant?

1 Answers

07/29/25 11:27pm

Excessive coolant has no impact, as the extra coolant will expand when heated during vehicle operation and be discharged through the pressure relief valve. Types of automotive coolant include: 1. Alcohol-based coolant; 2. Glycerin-based coolant; 3. Ethylene glycol-based coolant; 4. Propylene glycol-based coolant. Functions of automotive coolant: 1. Prevents freezing in low-temperature environments, which could cause the radiator and engine block to crack; 2. Prevents corrosion in the cooling system; 3. Reduces scale formation during circulation; 4. Absorbs heat, allowing the radiator to withstand high temperatures without boiling. Precautions for using automotive coolant: 1. Prevent coolant leakage; 2. Coolant is toxic—do not ingest; 3. Coolant is flammable—exercise caution to prevent fire hazards.

Can Fuel Additives Be Added After Refueling?

Fuel additives can be added after refueling, but the mixture may not be uniform enough in this case. It is recommended to add the fuel additive before refueling at the gas station. Follow the recommended ratio by adding the fuel additive to the car's fuel tank first, then refuel. This way, the added fuel additive will quickly dissolve thoroughly under the impact and vortex stirring of the fuel, ensuring a more uniform mixture. Gasoline-type fuel additives should be added to the gasoline tank, while diesel-type fuel additives should be added to the diesel tank. The two should not be confused. For the first use, fuel additives can be added continuously three to five times, each time following the proportion specified in the instruction manual. After driving 3,000 to 5,000 kilometers, repeat the process by adding the additive continuously three to five times again. This cycle is considered appropriate.

Where is the water temperature gauge in the Lavida car?

The new Lavida model does not have a water temperature gauge, only a water temperature warning light. When the water temperature exceeds 90 degrees, a red thermometer-like warning light will appear. Solutions for high water temperature include: 1. Insufficient coolant causing the engine to overheat—add coolant after the engine cools down; 2. A loose or broken water pump or fan belt causing the engine to overheat—replace the relevant parts; 3. Insufficient engine oil or substandard oil quality causing the engine to overheat—replace with high-quality oil. The Lavida is a sedan produced by Shanghai Volkswagen, with body dimensions of 4605mm in length, 1765mm in width, and 1460mm in height, a wheelbase of 2610mm, and a top speed of 200km/h.

Why does the car remote key have power but no response?

Reasons why the car key has power but no response when pressed: nearby interference; building obstruction; insufficient battery power; remote key circuit board failure. Here are the relevant details: Low battery: As the battery power decreases, the strength of the radio waves is also affected. Normal face-to-face use may not be a problem, but radio waves cannot penetrate buildings. Function of the remote key: The mechanism is a wireless communication system composed of a transmitter and receiver, belonging to low-power radio equipment. The control system in the car identifies the signal code through the electronic control unit (ECU). The first generation of car keys, even if they still use mechanical key ignition, also have remote locking and unlocking functions; more advanced car keys can have one-button start or sensing unlocking; some even more advanced keys can have remote start.

What is the difference between a direct store and a 4S store?

Here are the differences between a direct store and a 4S store: 1. A direct store is a chain store directly operated by the headquarters. The headquarters adopts a vertical management approach, directly commanding all retail outlets, which fully comply with the headquarters' directives. Vehicles are sourced from 4S stores, and services like after-sales maintenance are also conducted at 4S stores. Since they are not directly managed by the manufacturer, there are often significant price discounts available. 2. A 4S store adopts a "four-in-one" business model, including vehicle sales, spare parts, after-sales service, and information feedback. 4S stores have a unified appearance, logo, and management standards, and they only operate a single brand.

How to Cancel the Tire Pressure Warning Light?

The method to cancel the tire pressure warning light is as follows: 1. Locate and press the instrument information switch button on the multifunction steering wheel; 2. The tire pressure information of the vehicle will appear on the instrument panel. If the tire pressure is abnormal, the tire pressure warning will also appear here. Then, press the RES plus button on the multifunction steering wheel; 3. Switch to the tire pressure monitoring setup interface and press the reset button to reset the tire pressure monitoring. The standard tire pressure is approximately 2.2bar to 2.6bar. Excessive tire pressure can increase tire wear and may lead to a blowout, while insufficient pressure can increase fuel consumption and cause a bumpy ride. Generally, tire pressure can be slightly lower in summer and slightly higher in winter.

Are Racing Cars Manual or Automatic?

Racing cars are manual transmission, as manual transmission can better showcase the driving skills of racers. The reasons for using manual transmission in racing include: 1. Manual transmission is easier to control and more efficient; 2. Maintenance and repairs are simpler; 3. Manual transmission allows for faster starts; 4. Manual transmission offers better adaptability. The correct steps for starting a manual transmission vehicle are: 1. Starting on flat ground: Simply release the clutch to the semi-engagement point; 2. Starting with the foot brake: Press the foot brake while depressing the clutch and shifting into first gear, then release the clutch to the semi-engagement position. When the body slightly trembles and the front of the car lifts, release the foot brake to allow the vehicle to start moving slowly.
