What is Engine Coolant?

1 Answers

07/29/25 11:36pm

Coolant, also known as antifreeze, anti-freeze liquid, or radiator fluid, primarily functions to protect the engine and ensure its proper operation. It circulates within the engine radiator to provide anti-freeze, anti-boil, anti-rust, and anti-corrosion effects. Most coolants are red or green in color, and different types of coolant should not be mixed. Below is more information about coolant: 1. Function: Modern engines rely on both coolant and engine oil to lower the engine temperature, achieving a dual-cycle cooling effect. During normal operation, coolant gradually depletes, so it is important to replenish it in a timely manner while using the vehicle. 2. Precautions: The coolant level should neither be too high nor too low. The engine compartment's radiator has markings indicating the maximum and minimum coolant levels.

How to Remove Static Electricity from Cars in Winter?

Methods to remove static electricity from cars in winter: 1. Using anti-static spray can reduce the generation of static electricity in cars. Generally, spraying it on the clothes you wear can prevent static electricity caused by clothing friction; 2. Anti-static eliminators are very effective in eliminating static electricity. Their main working principle is to use diodes in the eliminator to dissipate the static electricity; 3. Using a car static grounding strap, which involves attaching a grounding strap to the rear of the car, allows the static electricity to flow directly into the ground. However, this method is ineffective on insulated asphalt roads; 4. Static electricity usually occurs in winter due to dry air and friction. Therefore, placing a humidifier in the car can effectively eliminate static electricity.

How Many Liters of Engine Oil Can a Car Hold?

The amount of engine oil a car can hold depends on the type of engine. Generally, small-displacement vehicles require 3.2 to 3.6 liters of oil, while larger-displacement vehicles need around 4.5 liters. The engine oil level should neither be too low nor overfilled. You can check the oil level using the dipstick—the oil mark should be between the upper and lower lines on the dipstick, slightly above the middle. Each car model has a different oil capacity, so the required amount of oil varies. The oil level should be just slightly below the upper mark on the dipstick. Engine oil, also known as motor lubricant, serves multiple functions, including lubrication, reducing friction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and providing cushioning and shock absorption for the engine.

How to Use a Vehicle Battery Charger?

How to use a vehicle battery charger: Connect the positive terminal of the charger to the positive terminal of the battery, and the negative terminal of the charger to the negative terminal of the battery.
