How to Determine the Amount of Antifreeze?

The indicator lines on the antifreeze reservoir mark the maximum and minimum levels of antifreeze that can be added. When the antifreeze level falls below the minimum mark, it indicates a deficiency, signaling the need for timely replenishment. Below are relevant details: 1. The full name of antifreeze should be "antifreeze coolant," meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. 2. There are many types of automotive antifreeze agents, such as calcium chloride (CaCl2) among inorganic compounds, methanol (CH3OH), ethanol (C2H5OH, commonly known as alcohol), ethylene glycol (C2H4(OH)2), glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oils, as well as everyday substances like sugar and honey. These can serve as the base liquid for antifreeze. When mixed with an appropriate amount of pure soft water (water containing little or no calcium or magnesium ions, such as distilled water, uncontaminated rainwater, or snowmelt, with a total hardness concentration between 0-30 ppm), they form what is generally referred to as antifreeze.

How to Deal with Fogging on the Inside of the Car Windshield?

Fogging on the inside of the windshield is primarily caused by the condensation of small water droplets when warm air inside the car comes into contact with the cooler windshield surface. Here are four solutions to address this issue: 1. Turn on the heater. Activating the heating system will quickly dissipate the fog. (Some vehicles feature a one-touch defogging function.) 2. Open the windows. This helps to release the warm air. 3. Apply chemical solutions. Applying these to the windshield can prevent further fogging. 4. Use the air conditioning for defogging. Adjusting the interior temperature to match the exterior temperature will help the fog to dissipate.

What causes the ESP light to illuminate in the Highlander?

Highlander ESP light illumination reason: Wheel speed sensor malfunction. Solution: Send to a 4S shop for inspection and repair as soon as possible. More information about the ESP light is as follows: 1. The ESP system involves many sensors, and the general cause of failure lies in the sensors, which may include loose wiring connectors, sensor function failure, false alarms, etc. When the ESP light is found to be on while driving, reduce the driving speed, avoid excessive steering, and find a nearby repair shop for inspection as soon as possible. 2.

When starting a car, should you release the handbrake first or shift into gear first?

When starting a car, you should first shift into gear and then release the handbrake, mainly for safety reasons. This is because when starting, you may not know if the ground is level. If the ground is sloped and you release the handbrake first, the car will be in a neutral coasting state, causing the vehicle to roll in the direction of the slope without any braking, which can easily lead to a safety accident. The sequence when parking is the opposite of starting. When parking, you should first engage the handbrake and then shift into neutral. This ensures the vehicle does not move to the greatest extent possible. This is because many people are accustomed to releasing the clutch and brake after shifting into neutral. If the gear is not correctly shifted into neutral or the parking spot is on a slope, the vehicle may move. However, for automatic transmission cars, when parking, you can directly shift into P (Park) and then engage the handbrake.
