12 engine maintenance tips to avoid expensive repairs

The engine is the heart of your car. Maybe your car is in good condition now, but it is important to perform regular maintenance. Fortunately, a little maintenance on your car engine can not only improve your driving experience, but also avoid high repair costs.

 

When it comes to engines, being proactive is always more economical than being reactive. So, what measures can you take to proactively maintain your engine? Here are some common maintenance methods and tips.

 

 

12 ways to protect your engine

• Change engine oil regularly
• Check the cooling system
• Check the air and fuel filters
• Check the timing kit
• Check for unusual noises and odors
• Check the spark plugs and wires
• Check for leaks
• Don't ignore warning lights
• Maintain good driving habits
• Clean the engine compartment regularly
• Use recommended fuel and oil
• Professional engine checkup once a year

 

1. Regularly change the engine oil

We all know the importance of regular inspection and replacement of engine oil, because it is the lubricant for various engine parts, but do you know how often you need to check whether the engine oil needs to be replaced? Usually, an inspection is required every 5,000-8,000 kilometers. You can also check the manual to find out the specific oil change time for your own car.

 

Maintenance suggestions:

• Check the oil level regularly to prevent lubrication failure
• And replace the new oil filter at the same time to prevent impurities from circulating into

 

 

2. Check the cooling system

The worst thing is an overheated engine, because metal will deform due to high temperature. This will cause engine failure, which will require a new engine. It is crucial to ensure that the engine's cooling system (radiator, hoses, coolant and other related parts) is maintained.

The coolant should be a bright color (green/pink) and needs to be replaced if it becomes cloudy.

 

Maintenance suggestions:

• Open the water tank auxiliary water bottle every month to check whether the coolant is within the scale range.
• Replace the coolant every two years to prevent rust and scaling from clogging the waterway.

 

 

3. Check the air and fuel filters

The engine is the heart of the car. Just like a person, it needs to breathe. It can run better with a constant air flow. If the air and fuel filters are not checked for a long time, dust, leaves, etc. will enter the engine, which will cause blockage and fail to run effectively. Regular inspections help to increase the service life of the engine and ensure safe driving.

 

Maintenance suggestions:

• Clean or replace filters regularly

 

 

4. Check the timing kit

The timing kit is a key part of the engine operation, ensuring the normal operation of all engine components (valves, pistons, etc.). If there is a problem with the timing kit (loose, broken), the movement of the engine valve and piston may be misaligned, resulting in power loss and even damage to the engine. Different timing kits have different replacement cycles, generally between 60,000 and 100,000 kilometers.

 

Maintenance suggestions:

• Replace belts or chains regularly

 

 

5. Check for abnormal sounds and odors

If the engine makes abnormal noises, it may be that the bolts are loose or there may be a problem with the oil pump. If there is an odor, it is also a precursor to problems with internal parts. Whether it is an abnormal sound or smell, you need to stop the car for inspection.

 

Maintenance suggestions：

• Once you hear abnormal noises such as metal knocking, stop the car immediately and carefully check whether the engine is short of oil or overheating.
• If you smell a burnt smell or oil level, check for leaks or circuit failures.

 

 

6. Check the spark plugs and wires

When it comes to engine maintenance, spark plugs and wires may not be your first choice. But without sparks, there will be no combustion, without combustion, there will be no progress, and they are also extremely consumable key components. So if the spark plugs are not working properly, it may cause misfires and damage the engine.

 

Maintenance suggestions：

• Replace spark plugs and wires regularly
• Check spark plugs every 30,000-50,000 kilometers

 

 

7. Check for leaks

If you find a leak on the ground, you must pay attention and check and repair it. It is usually a problem with the rubber hose (rupture), but it is not the only culprit. A hole in the radiator, a damaged cylinder head gasket or worn brake pads may also cause leaks.

 

If you can't find the source of the leak, you must send the car to a repair station for a comprehensive inspection to avoid damaging the engine and affecting safe driving.

 

Maintenance suggestions:

• Check coolant, power steering fluid and other liquids regularly

 

 

8. Don't ignore warning lights

As long as you see the warning light on the dashboard, you need to stop and check. If the engine light is on, it means that there is a problem with the engine system. Many auto repair shops will provide free inspections.

 

Maintenance suggestions:

• After the engine warning light is on, stop the car quickly for diagnosis and determine the fault location

 

 

9. Maintain good driving habits

Good driving habits can effectively extend the life of the engine. Try to avoid driving behaviors such as sudden acceleration and sudden braking when driving, which will help reduce engine fatigue, which also helps save fuel.

 

Maintenance suggestions:

• Avoid sudden braking, especially in cold winter weather or on icy and snowy roads
• When starting the vehicle in winter, avoid emergency acceleration and give the engine time to warm up

 

 

10. Clean the engine compartment regularly

The dirt and oil stains on the engine surface may affect its exhaust performance. Regular cleaning of the engine can help to detect potential exhaust or damage problems early.

 

Maintenance suggestions:

• When cleaning the dirt on the engine surface regularly, be careful to avoid water entering the internal components.
• Wipe the engine surface with a dry cloth or special cleaner every 2-3 months.

 

 

11. Use recommended fuel and oil

Improper oil can cause knocking, carbon deposits and even damage the three-way catalytic converter.

 

Maintenance suggestions:

• Always fill the gasoline with the recommended grade in the vehicle manual; do not choose low-grade fuel for cheapness.
• Choose a regular brand of fully synthetic or semi-synthetic engine oil with a viscosity grade that meets the engine requirements

 

 

12. Have a professional engine physical examination once a year

 

It is difficult to find deep problems in daily inspections, and professional equipment is required for auxiliary diagnosis.

 

Maintenance suggestions:

• It is recommended to conduct throttle, fuel injector, ignition system, computer testing and other projects once a year.
• If the vehicle condition deteriorates significantly (such as increased fuel consumption, lack of power), do not wait, and bring it to the factory for inspection in time.

 

 

 

Importance of Engine Maintenance

The engine is one of the most important parts of a car, and also one of the most expensive. Maintaining the engine well ensures that all parts function properly, reduces wear and tear, and reduces unnecessary repair costs. Good car engines Good car engines ensure safe driving for you and your family.

 

Summary

Without the engine, the car cannot function. With this in mind, you must maintain the engine regularly.

FAQ

1. How often should I change the engine oil?

It is recommended to change it every 5,000~8,000 kilometers or 6 months.

 

2. What will happen if I don't maintain the engine?

It will cause serious carbon deposits, reduced fuel efficiency, and even engine scrapping, and the repair cost is as high as thousands of yuan.

 

3. Do I have to change the engine oil when it turns black?

Not completely. It is normal for synthetic engine oil to turn black during use. The basis for judging whether it really needs to be changed is: the viscosity becomes thinner, there is an odor, there are impurities, or the replacement cycle specified by the manufacturer (such as 6 months or 8,000 kilometers) is reached.
