What to Do If the Thermostat Fails?

The thermostat should be replaced immediately if it fails. The thermostat is part of the cooling system and is used to control the coolant's circulation between the large and small loops. Water-cooled engines rely on the continuous circulation of coolant within the engine for heat dissipation. Water-cooled engines require antifreeze, which has two circulation paths within the engine: one is the large loop, and the other is the small loop. When the antifreeze is in the small loop, it does not pass through the radiator for cooling, which helps the engine warm up quickly. Once the engine reaches its normal operating temperature, the antifreeze switches to the large loop, where it passes through the radiator for cooling, keeping the engine within a reasonable operating temperature range. The component responsible for switching between the large and small loops is the thermostat. If the thermostat is damaged, the antifreeze cannot switch between the loops, which will affect the engine's normal operation. If the antifreeze remains in the small loop, it can cause the engine to overheat. Continuing to operate the engine under overheating conditions can easily lead to cylinder scoring.

Why does the car hesitate when starting?

The possible reasons for the car hesitating when starting are as follows: 1. Excessive carbon deposits: The most common cause of severe hesitation is a dirty throttle body or excessive carbon deposits in the fuel injectors. The uneven quality of fuel and congested urban road conditions contribute to the easy formation of carbon deposits. A dirty throttle body can cause it to not close properly or the idle stepper motor to stick, both of which can result in high engine idle speed and hesitation after a cold start. 2. Poor ignition system performance: Faulty spark plugs or ignition modules, as well as poor spark plug firing, can also lead to hesitation. Check the condition of the spark plugs, high-voltage wires, and ignition coils. Such faults are relatively common and can be resolved by replacing the relevant components. 3. Unstable fuel pressure: If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, hesitation can occur. It is recommended to visit a 4S shop to check the fuel supply pressure and the intake pressure sensor for normal operation.

What does a commercial version of a car mean?

Commercial vehicles refer to vehicles that have been approved by the competent authorities by the end of the reporting period and are eligible to participate in commercial operations. This includes vehicles that are technically sound, under repair, awaiting repair, long-term parked, and those intended for scrapping but not yet approved by the higher authorities. However, it does not include non-commercial vehicles of the enterprise (such as cable cars, tankers, trucks) or borrowed passenger vehicles. Cars generally come in standard, low, mid, and high-end versions, which respectively refer to: 1. Low-end: Generally simplified configuration, without leather seats or power windows, lacking many electronic control functions; 2. Standard: Includes normal electric controls such as power windows, power steering, air conditioning, etc.; 3. Mid-range: Slightly more advanced than standard, not only including all standard features but also possibly adding airbags, sunroof, leather seats, power seats, seat heating, etc.; 4. High-end: Higher than all the above configurations, can also be considered the flagship version of the model.

Why does the Odyssey's exhaust pipe make a popping sound?

There are many reasons for abnormal exhaust pipe noise, mainly including exhaust pipe aging, vehicle three-way catalytic converter failure, vehicle ignition system failure, abnormal concentration of combustible mixed gas, etc. The specific reasons are as follows: 1. Exhaust pipe aging: When a car is too old, the exhaust pipe is prone to aging problems, leading to loosening, detachment, or holes, which ultimately cause abnormal exhaust pipe noise. This situation is relatively simple to resolve, requiring only re-fixing or replacing the exhaust pipe. 2. Vehicle three-way catalytic converter failure: If the vehicle's three-way catalytic converter fails, it cannot properly purify exhaust gases, causing them to block and compress inside, leading to abnormal exhaust pipe noise. This situation requires professional inspection and repair at a repair shop or 4S store. 3. Vehicle ignition system failure: If the vehicle's ignition system fails, fuel cannot burn normally in the cylinders, and the vehicle may experience symptoms such as weak acceleration, easy stalling, and abnormal exhaust pipe noise. This situation also requires a detailed inspection of the vehicle's ignition system. 4. Abnormal concentration of combustible mixed gas: If the concentration of mixed gas in the engine is too high or too low, it will cause abnormal combustion, leading to abnormal exhaust pipe noise. This situation is more complex and requires professional inspection at a repair shop or 4S store.

What are the symptoms of a bad throttle cable?

There will be failure modes. The main failure modes of a throttle cable include sticking, breaking, wear, and damage. Below is relevant information about the vehicle throttle: 1. Function of the car throttle: The throttle in a gasoline engine does not control the fuel injection volume but rather the opening degree of the throttle valve. A smaller opening means less mixture enters the cylinder, resulting in lower engine power output, and vice versa. 2. Solutions for a heavy throttle: If the throttle feels heavy, you can perform a fuel system cleaning. Alternatively, try accelerating further to see if the engine speed increases but the vehicle speed does not. If this occurs, it may be due to a damaged sensor inside the transmission locking the overdrive gear.

Can a gasoline indicator be changed to an electric one?

The nature of the indicator cannot be changed. Here is the relevant introduction about gasoline grades: 1. Different grades of gasoline have different densities: The most commonly encountered are 92 and 95 grades. The density of 92 gasoline is approximately 0.72g/ml, 95 gasoline is about 0.725g/ml, and 98 gasoline is about 0.737g/ml. This shows that the higher the gasoline grade, the greater its density, primarily because gasoline is a mixture, and different grades are formulated by adding various additives to the base gasoline. 2. Grades: Higher-grade gasoline uses more additives, and the density of these additives is greater than that of the base gasoline. Therefore, the higher the gasoline grade, the greater its density. It is worth mentioning that the reason gasoline has different grades is mainly due to their different anti-knock properties, not that higher grades have fewer impurities. The higher the gasoline grade, the better its anti-knock performance, making it less likely for the engine to experience premature combustion during operation. Additionally, the engine's compression ratio determines the gasoline grade.
