What is the normal coolant temperature for a car?

The normal temperature is indicated by the center of the needle--90℃. Here are specific details about coolant temperature: 1. Coolant is an essential part of a car's engine. It circulates within the engine cooling system, carrying away excess heat generated during engine operation, allowing the engine to run at its optimal working temperature. 2. Both excessively high and low temperatures can cause damage to the car. Lower temperatures indicate stronger heat dissipation. Excessively low temperatures mean greater heat loss through dissipation, and lower working temperatures result in higher fluid viscosity. Increased viscosity leads to greater resistance in moving parts, reducing output power. 3. Excessively low cylinder wall temperatures prevent proper formation and combustion of the air-fuel mixture, increasing fuel consumption. The engine becomes harder to start, operates with greater resistance, and fuel evaporation becomes difficult. Unvaporized fuel due to low temperatures can wash over cylinder surfaces, damaging the lubricating oil film and accelerating component wear.

How to Use Turn Signals When Entering a Roundabout

There are three scenarios for using turn signals when entering a roundabout: turning left upon entering, going straight upon entering, and turning right after entering. The details are as follows: Turning left upon entering: If the vehicle intends to turn left, it should prioritize selecting the left lane inside the roundabout. Since the vehicle needs to merge from the outer lane to the inner lane, it should activate the left turn signal when entering the roundabout. Before exiting the roundabout, the driver should switch to the right turn signal in advance to give sufficient warning to vehicles behind. After ensuring safety, the vehicle should start changing lanes from the inner lane to the outer lane and finally exit the roundabout. Going straight upon entering: If the vehicle intends to go straight, it should prioritize selecting the middle lane inside the roundabout and merge into the middle lane without obstructing vehicles behind. Since no lane change is required after entering the roundabout, the left turn signal is unnecessary. When preparing to exit the roundabout to continue straight, the vehicle may need to cross the right lane inside the roundabout, potentially hindering vehicles behind. Therefore, the right turn signal should be activated to alert other vehicles before exiting the roundabout. Turning right after entering: If the vehicle intends to turn right to another intersection, it should quickly select the right lane inside the roundabout to exit or may choose to turn right from the outer lane. The situation when entering the roundabout is similar to going straight, so the left turn signal is also unnecessary. After selecting the corresponding intersection, the driver should activate the right turn signal in advance and exit the roundabout by turning right after ensuring safety. Typically, roundabouts are designed with four lanes: the left lane for left turns, the middle two lanes for going straight, and the right lane for turning right to exit the roundabout.

What Causes Rapid Consumption of Antifreeze?

Rapid antifreeze consumption is generally caused by the following three reasons: 1. Radiator damage: Poor sealing of the upper and lower water chambers leads to antifreeze leakage. 2. Overflow tank: Loose connections at the water pump interface and cooling system pipe joints result in poor sealing and antifreeze leakage. 3. Cylinder head gasket damage: Excessive flatness deviation, warping of the cylinder head and block mating surfaces, or loose cylinder head fastening bolts allow high-temperature, high-pressure gases from the cylinders to enter the cooling system, causing rapid coolant consumption. Additional information about antifreeze: The full name of antifreeze should be antifreeze coolant, meaning it is a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the vehicle is parked in cold winter conditions. Many people think antifreeze is only used in winter, but in fact, it should be used year-round.

How to Set Automatic Mirror Tilt When Reversing?

To set the automatic mirror tilt when reversing, first engage reverse gear, then press and hold the driver's seat memory button on the left side until you hear a sound, indicating successful memory. Configurations with seat memory have this function. When reversing, rotate the mirror adjustment to the R position, and it will automatically tilt down. Below are the detailed steps for setting the automatic mirror tilt when reversing: 1. Power on the car but do not start it (press the start button without stepping on the brake); 2. Set your memory seat positions 1, 2, and 3, and select your seat position; 3. Choose the side mirror you want to set by pressing the mirror adjustment selection button (left or right); 4. Step on the brake, shift to R gear, and the selected mirror will automatically tilt down to the factory preset position. Use the 4-way adjustment button to set it to your desired position; 5. Press and hold the seat memory button (1, 2, or 3) for about 2 seconds, depending on which memory position you selected; 6. Step on the brake, shift to P gear, and press the mirror adjustment selection button once more to complete the setup.

What to Pay Attention to When Changing Engine Oil and Oil Filter

Here are the precautions for changing the oil filter: 1. After the engine has been running, the exhaust pipe will also be very hot, so be careful when working around the exhaust pipe. Be cautious when loosening the oil drain bolt while the engine is hot, as the oil temperature is high to avoid burns. 2. Properly dispose of waste oil and old filters. Waste oil, which is highly toxic, must never be disposed of with household waste, and draining it into the sewer is also illegal. 3. Oil filters come in various types, but only high-quality filters can ensure maintenance quality, so premium genuine oil filters must be used. Using oil filters that do not meet specifications can cause engine oil leaks and contamination. A special reminder: before installing a new oil filter, the rubber gasket on the cylinder block must be replaced.

What is a Retarder?

The automotive retarder refers to a device that, when activated during deceleration or long downhill driving, allows the vehicle to slow down smoothly, avoiding the wear and heat generated by frequent use of the brakes. Below is a detailed introduction to the retarder: 1. Based on different working principles, automotive retarders can be classified into several typical structural forms, including engine retarders, hydraulic retarders, electric turbo retarders, motor retarders, and aerodynamic retarders. 2. Depending on the form of braking torque application, automotive retarders can be divided into primary retarders (those acting on the front end of the transmission) and secondary retarders (those acting on the rear end of the transmission). 3. When a vehicle is descending a long slope, using exhaust braking can achieve good braking effects. However, for heavy-duty mining dump trucks, the effectiveness of exhaust braking is limited, and it can cause some degree of damage to the engine. Therefore, mining dump trucks equipped with hydraulic-mechanical transmissions are also fitted with hydraulic retarders.
