What Are the Causes of High Engine Coolant Temperature?

Car engine coolant temperature may become excessively high due to the following reasons: 1. Installation-related causes: Excessive distance between the radiator and the engine, or the fan being positioned outside the air duct. This can be resolved by adjusting the radiator's mounting position. If the air conditioning condenser obstructs the radiator, there are two solutions: First, if there's sufficient space in the engine compartment, relocate the condenser; Second, if the alternator has sufficient output capacity, install an electric fan in front of the condenser. 2. Maintenance-related causes: Modern engines have compact designs with narrow coolant passages. In southern regions, always use softened water or distilled water to prevent scale buildup in the cooling system. In northern areas, only use genuine coolant (antifreeze) from authorized service stations to prevent cylinder head corrosion.

Where to Check a Vehicle's Emission Standards?

Methods to check are as follows: 1. Take the vehicle registration certificate (green book) and driving license to the vehicle management office and ask the staff to check. 2. For a newly purchased vehicle, there is a new vehicle conformity certificate which contains the vehicle's emission standards. However, when registering the license plate, the new vehicle conformity certificate will be retained by the vehicle management office for record purposes. Therefore, it is recommended to make a copy for personal use when buying a new vehicle. 3. Website inquiry: Log in to the "Motor Vehicle Environmental Protection Website", click "This inquiry system is only for newly produced vehicles. Click here to inquire about other vehicles' compliance status". Follow the prompts to enter the information and click the inquiry button. Finally, compare the vehicle model and engine model based on the inquiry results, and verify with the vehicle's manufacturing date and the public date in the inquiry results. 4. Make a rough distinction based on the time of license plate registration. This method is less accurate because the implementation time of emission standards varies across the country. In the past, there was an environmental protection sticker during annual inspections, through which you could check the vehicle's emission standard. However, since 2017, the environmental protection sticker has been abolished during annual inspections.

Why does the right reverse parking in Subject 2 result in the car touching the line?

One situation where the rear of the car touches the line after reversing into the parking space is that the car body is not straightened before entering the space, and the steering wheel is turned back too late; another situation is that the reference point is observed too late when entering the space, causing the car to be off-center when parking. Relevant explanations are as follows: 1. First, there are two types of reverse parking: left reverse parking and right reverse parking. When reversing into the parking space, observe the rearview mirror at the entrance of the space. Compare the reserved distance between the rear of the car and the corner of the space in the rearview mirror when the car reaches the control line at the entrance. Generally, the length of a foot is just right to turn the steering wheel back. 2. Under the premise of ensuring no stopping and slow speed, observe the distance between the car body and the edge line of the parking space in the rearview mirror, and adjust accordingly by moving forward or backward.

Why Does the Car's Water Temperature Gauge Not Rise in Winter?

In winter, if the car's water temperature gauge does not rise, it is likely due to a faulty thermostat or the radiator fan running continuously. When there is a circuit malfunction, the electric fan may run continuously. Additionally, a damaged silicone oil clutch can also cause the fan to run non-stop. These factors can prevent the water temperature from rising. The related explanations are as follows: 1. The thermostat in a car functions like a valve. It is typically installed at the outlet of the radiator, which is the inlet of the water pump. During operation, when the coolant temperature is low, the thermostat blocks the low-temperature coolant from the radiator, allowing the engine's water temperature to rise quickly. 2. When the engine's water temperature reaches a certain level, the valve gradually opens, and the coolant from the radiator starts circulating again. If the thermostat malfunctions and the valve fails to close in time, the coolant remains in a state of large circulation. Under such conditions, the engine's water temperature will not rise.

How to Check for Brake Drag?

Hydraulic brake system brake drag diagnosis methods are as follows: 1. Lift the car and manually rotate the wheels without pressing the brake pedal. If a certain wheel cannot rotate, it indicates brake drag on that wheel; if all wheels cannot rotate, it indicates brake drag on all wheels. 2. If there is brake drag on an individual wheel, first loosen the bleeder screw of that wheel's brake cylinder. If brake fluid spurts out rapidly and the wheel can then rotate freely, it indicates a blockage in the brake line of that wheel, and the brake cylinder failed to return oil, which should be replaced promptly. If the wheel still cannot rotate, remove the wheel and disassemble it to inspect the brake. 3. If there is brake drag on all wheels, first check if the brake pedal free travel meets the requirements. If the free travel is too small, adjust it promptly; check the return condition of the brake pedal by pressing it firmly to the floor and quickly releasing it. If the pedal returns slowly, it indicates a failure in the brake pedal return spring, which should be replaced or repaired.

Why Does Engine Oil Level Increase in Cars?

Oil level increase is primarily caused by incomplete combustion or coolant leakage. The specific reasons are as follows: 1. For example, clogged air filter; faulty fuel injector; damaged spark plug, cylinder misfire; cylinder wear, insufficient cylinder pressure; improperly closed valves; blown cylinder head gasket; sand holes or cracks in cylinder liner or cylinder head, etc. Unburned fuel or coolant entering the oil pan through the cylinder walls can lead to an increase in oil level. 2. The above issues can dilute or emulsify the oil, impair lubrication, accelerate wear, and damage the engine. 3. Performing regular daily inspections and maintenance, as well as scheduled check-ups, plays a crucial role in preventing oil level increase.
