15w40 engine oil can be used in summer. Here are specific methods for selecting engine oil for cars: Performance selection: If you prioritize long-lasting performance of engine oil, you can choose Mobil engine oil; if you focus on the cleaning effect of engine oil on the engine, you can use Shell lubricants; if you need lubricants with strong oil film toughness, it is recommended to use Castrol. Driving conditions: For frequent driving in congested areas, older vehicles, or long-distance heavy-load transportation, the viscosity of the lubricant can be appropriately increased. Engine type: For naturally aspirated engines, mineral oil and semi-synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-grade lubricants with better fluidity, preferably fully synthetic oil.

How to Bleed Air from the Clutch Alone?

Bleeding air from the clutch can be done as follows: Manual Bleeding Method: Repeatedly press and release the clutch pedal with your foot. When you feel resistance while pressing, use a wrench to loosen the bleeder screw on the booster, then tighten it after bleeding. Repeat this process multiple times until all air is expelled. Assisted Bleeding Method: Connect one end of a rubber tube to the air pipe fitting to utilize air pressure for bleeding. Bend the tube into a U-shape with your left hand, and aim the other end at the vent hole on the reservoir cap with your right hand. Slowly release the bent section with your left hand (air pressure should not exceed 3 kPa). At this point, loosen the bleeder screw on the booster. When fluid flows out continuously without bubbles, tighten the bleeder screw and stop the air supply. Then, press the clutch pedal with your foot. If you feel resistance, it indicates that the air in the clutch hydraulic line has been successfully bled.

Why does the car air conditioning work in the morning and evening but not at noon?

The reasons why the car air conditioning works in the morning and evening but not at noon are as follows: 1. Lack of refrigerant: This is the main cause of air conditioning failure in most vehicles during summer. When there is insufficient refrigerant in the car's air conditioning pipes, the pressure in the pipes decreases, and the amount of heat removed also reduces, giving the impression that the air conditioning is not blowing cold air. 2. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. In spring, poplar catkins or dust from smog can accumulate on the condenser, leading to phenomena such as excessive engine temperature or poor air conditioning performance. Therefore, it's essential to check if the radiator is clogged with debris after spring.
