Self car maintenance beginner: engine maintenance

Then, shall we start self-maintenance in earnest? The easiest part for those who are new to self-maintenance to try is supplementing and replacing various oils. It is especially useful to know basic maintenance tips for the engine part, the heart of the car. Of course, it’s the most important part and it needs to be handled more carefully.

The relatively easy maintenance of the engine part is the replacement of engine oil, engine filter and air cleaner element. Engine oil is a little trickier than replenishing washer fluid or coolant, so it is usually replaced at a workshop. Recently, there have been a lot of people who do it themselves. You can select a product that satisfies the viscosity and quality specifications and exchange it by referring to the’Recommended Oil Specification Table’ in the vehicle manual . When changing the oil, it is good to replace the engine filter and the air cleaner element that filters foreign substances in the air inhaled by the engine.

In particular, the air cleaner element can be easily replaced by loosening a few bolts, so anyone can challenge easily. It will last longer if it is periodically cleaned and refitted, or it can be disassembled and replaced with a new one in the same way. However, when locking nuts and bolts, be sure to tighten as much as possible by hand, but remember to keep the proper torque!

Q. Do you know the engine oil change cycle for my car?

In general, the engine oil exchange cycle is known as’every 5,000 km’. It can be said that the exchange cycle is slightly different depending on the vehicle type and driving habit. It’s a good idea to set an appropriate replacement cycle for your car by applying the mileage, driving habits, and usage environment to the standards in your car’s instruction manual!

Now, once you have gained some confidence through engine maintenance, it’s time to challenge yourself to repair your brakes and lights! In the case of the brake system, the degree of replenishment and replacement of brake fluid and brake lining is possible through self-maintenance. From checking the brake hoses, pedals and levers, you can look through the brakes. In the case of the brake lining, if you hear a sound when you step on the brake and release your foot, it is a sign that it is time to replace it. However, it is a part that is directly related to safety, and if you are not confident, it is recommended that you obtain an expert maintenance.

Except for headlights and speed indicators, various electric devices such as electric bulbs, batteries, fuses, and signal lamps are also available for self-service! Recently released vehicles can be used semi-permanently using LED bulbs, but if the vehicle is a little older, it is necessary to change the bulbs periodically. First of all, you need to check the appropriate light bulb standard for your car and purchase it to prevent an accident that does not light up or melts the wiring.

Touching the glass part of a new light bulb with your hands shortens the lifespan, so be sure to wear gloves. In the case of the headlamp, open the bonnet and loosen the fixing clip slightly to replace it. In the case of the rear lamp, turn the socket out and replace it with a new light bulb. It’s a bit higher level of difficulty than going with a fluorescent lamp, so try using light bulbs that fit the standard!

Advanced self-maintenance: for experts in other areas of difficulty!

Points to be aware of when self-repairing a car!

As safety is the first, there are many things to be aware of when doing self car maintenance. First of all, you must thoroughly familiarize yourself with the car manufacturer’s maintenance manual.

Also, it is very important to properly dispose of waste such as waste oil, waste antifreeze, and waste batteries that come out after self-maintenance! Since waste oil or waste antifreeze is a designated waste and is a substance that is harmful to the environment, you must ask the seller or a designated waste disposal company to dispose of it. There is also a method of requesting disposal at a nearby workshop. In the case of used batteries, online retailers often collect them, so don’t worry.
