When all kinds of dirt and oil stains accumulate too much in the engine compartment, it will cause trouble for the driving and maintenance of the vehicle. This garbage may cause potential risks and damage during engine operation, so regular thorough cleaning to ensure that the engine remains in good condition and consistent operation has become very necessary. In this article, we will discuss how to clean the engine compartment thoroughly and efficiently.Step 1: Prepare tools to clean the engine compartment and use several tools, including a hard brush, a soft brush, butyl gloves, concentrated car wash liquid, old towels, cleaning workshops and sprinklers. Make sure that all tools are clean and sterilized, as this helps prevent impurities and oil stains that may cause pollution. Step 2: To place the cover, you need to cover the ground and other parts around the engine to protect them from cleaning fluid pollution. Using old towels or plastic cloths can effectively protect these areas from pollution. Step 3: Blow away the garbage with compressed air. Before starting to clean the engine, you need to blow away the dirt and dust accumulated around it. Using compressed air or high-efficiency vacuum cleaners can do this job well. This can not only get rid of the "waste" in the engine compartment that may harass you, but also helps reduce the amount of impurities and oil stains brushed off by hand.Step 4: Start cleaning and mix concentrated car wash liquid and water in a ratio of 1:3 and pour it into the sprinkler. Spray the mixture down from the engine drain of the vehicle to ensure that the liquid covers all surfaces. Note that do not point the nozzle at vulnerable parts such as electronic components, chips or wire harnesses. A special reminder is that high-end tires such as older or Michelin tires can be cleaned with petroleum cotton alcohol, etc., but this cleaning method is not recommended for new tires due to the material used. Step 5: Use a brush to clean certain parts. Use a hard brush to clean every groove in the engine compartment, including all thin sheets, compressors, motors, pumps and other parts from the new fuel tank to the air purifier. Don't forget to use a soft brush for the bulges and details of the area to achieve a closer effect.Step 6: Use a sprinkler to rinse the engine compartment until the detergent and dirt are cleaned. Make sure to clean the inner and outer surfaces to keep the entire engine compartment clean. Step 7: Use a brush or towel to gently dry the impurities, and then use a dryer or towel to dry it completely, or let it dry naturally. Do not close the hood until you make sure the engine is completely dry. Step 8: After the test engine is cleaned, please prevent the liquid from entering the area that may cause damage, such as electronic components or chips. Finally, put on carefully cleaned gloves to start the engine and make sure it is working properly so as not to waste your good efforts. In short, regular cleaning of the engine compartment is not just a simple task, but requires a lot of tools, time and patience. However, it can only be activated like cleaning.Such meticulous maintenance of the cabin can extend the service life of the vehicle and ensure that the engine can maintain good working condition even when the temperature is extreme.
