How to Maintain a Car Air Conditioner?

Why does the engine temperature still rise after adding antifreeze?

The reason why the engine temperature still rises after adding antifreeze is: improper addition and replacement of antifreeze, which causes premature blockage of the engine water channel and radiator, resulting in high engine temperature. Antifreeze should be replaced every two years, and original equipment manufacturer (OEM) antifreeze must be used during replacement and addition. If the concentration is too high, it will lead to poor heat dissipation and engine overheating. The full name of antifreeze is antifreeze coolant, meaning a coolant with antifreeze function. It can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when parking in cold winter. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It has excellent performance such as antifreeze in winter, anti-boil in summer, and anti-scale and anti-corrosion all year round.

Can I Change the Antifreeze Myself?

You can change the antifreeze yourself. The specific steps are as follows: 1. Before replacing the antifreeze, ensure the car is in a cold state. Open the radiator drain valve to drain the antifreeze. 2. Pour in clean water and keep the engine idling until the water coming out of the radiator is clear. 3. Wait for all the water to drain, then close the drain valve and the engine. Add new antifreeze until the liquid level is between the max and min marks. 4. After idling the engine for two to three minutes, the antifreeze level may drop slightly. At this point, top it up to the appropriate level again. Antifreeze, also known as antifreeze coolant, is a coolant with antifreeze properties. It 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.

How to Detect Car Air Conditioning Faults?

Methods to detect car air conditioning faults: 1. Check the air volume from the air conditioning vents. If the air volume is insufficient, inspect the air filter element and remove any debris if present; 2. Listen for abnormal noises near the compressor. If any are heard, check the compressor's installation; 3. Inspect the condenser's heat dissipation fins for dirt coverage. If dirty, clean them; 4. Check for oil stains at each connection point of the refrigeration cycle system. If oil stains are found, it indicates a leak. Tighten the connection or replace the part; 5. Turn the blower to low, medium, and high settings, listen for any abnormal noises, and check if the blower operates normally. If there are noises or abnormal operation, replace the blower.
