Why is the car heater not hot enough?

Car heater not being hot enough may be due to a thermostat that is constantly open or opens too early, a damaged or slipping water pump impeller, or airlocks in the engine cooling system. Below are the reasons and solutions for insufficient car heater performance: 1. Thermostat constantly open or opening too early: This causes the cooling system to enter the major circulation cycle prematurely. When the external temperature is very low, especially while driving, the cold air quickly cools the antifreeze, preventing the engine coolant temperature from rising, and thus the heater won't produce hot air. 2. Damaged or slipping water pump impeller: This results in insufficient flow to the heater's small radiator, preventing heat from rising.

Will speeding on the highway result in penalty points?

In actual enforcement, speeding on the highway does not result in penalty points. Below is relevant information about highway speeding: 1. Highway speeding penalty regulations: The new highway speeding penalty regulations specify four types of penalties for speeding by small and large vehicles: warning, 3 penalty points; 6 penalty points or possible revocation of the motor vehicle driver's license; mandatory revocation of the motor vehicle driver's license. 2. Precautions for highway driving: Although the work isn't strenuous, prolonged driving can still lead to fatigue. Beyond fatigue, vehicles require good heat dissipation. After prolonged driving, all moving parts such as the engine, transmission, tires, and brakes become very hot. When two moving parts rub together, the hotter they become, the more active the molecular structure on their surfaces, leading to more severe wear.

Once the front of the vehicle crosses the control line, it means entering the test area of that item, and the test must be completed according to the rules of that item. 3. Correct mistakes promptly: When an operation error is found, it should be corrected in time to ensure the accuracy of the operation and reduce the chance of point deduction.

What are the advantages and disadvantages of automatic transmissions?

Automatic transmissions have the advantage of convenient gear shifting and simple operation; the disadvantage is their complex structure and high maintenance costs. Below is relevant information about automatic transmissions: 1. Introduction: The core of an automatic transmission lies in achieving automatic gear shifting. Automatic gear shifting means that while driving, the driver controls the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions. 2. Maintenance knowledge: Regularly check whether the automatic transmission fluid level is normal. Start the engine, warm up the transmission fluid to about 50°C, then move the gear selector through each position for 2 seconds before placing it in the parking gear. At this point, the normal fluid level on the dipstick should be between the maximum and minimum lines. If it is insufficient, promptly add the same quality of fluid.
