What to Check in Car Engine

Oil Level and Condition

Checking your oil level and condition is one of the most important things you can do to keep your engine running smoothly. Oil lubricates the moving parts of your engine, and it also helps to cool it down. If your oil level is low, or if it is dirty or contaminated, it can cause your engine to overheat or seize up.

To check your oil level, simply pull out the dipstick and wipe it off with a clean cloth. Then, reinsert the dipstick all the way into the oil pan, and pull it out again. The oil level should be between the two marks on the dipstick. If it is below the lower mark, you need to add oil.

To check the condition of your oil, look at its color and consistency. New oil is typically a light amber color, but it will darken as it gets dirty. If your oil is very dark, or if it is thick and sludgy, it needs to be changed.

Coolant Level and Condition

Coolant is another important fluid that helps to keep your engine running smoothly. Coolant circulates through your engine, and it helps to absorb heat. If your coolant level is low, or if it is dirty or contaminated, it can cause your engine to overheat.

To check your coolant level, simply look at the coolant reservoir. The reservoir is usually located near the top of the engine, and it is typically made of clear plastic. The coolant level should be between the two marks on the reservoir. If it is below the lower mark, you need to add coolant.

To check the condition of your coolant, look at its color and consistency. New coolant is typically a bright green color, but it will darken as it gets dirty. If your coolant is very dark, or if it is thick and sludgy, it needs to be changed.

Battery

The battery is responsible for starting your car, and it also provides power to the electrical system. If your battery is dead or weak, you will not be able to start your car.

To check your battery, simply look at the terminals. The terminals should be clean and free of corrosion. If the terminals are corroded, you can clean them with a battery terminal cleaner.

You can also check the battery voltage with a voltmeter. The battery voltage should be between 12.6 and 13.2 volts. If the battery voltage is below 12.6 volts, you need to charge the battery.

Air Filter

The air filter cleans the air that enters the engine. If the air filter is clogged, it can restrict airflow to the engine, which can cause the engine to lose power and run less efficiently.

To check the air filter, simply remove it from the air filter housing. The air filter should be clean and free of dirt and debris. If the air filter is dirty, you need to replace it.

Spark Plugs

Spark plugs ignite the air-fuel mixture in the engine. If the spark plugs are worn or dirty, they can cause the engine to misfire.

To check the spark plugs, simply remove them from the engine. The spark plugs should be clean and free of deposits. If the spark plugs are dirty, you need to replace them.

Timing Belt

The timing belt synchronizes the movement of the crankshaft and the camshaft. If the timing belt breaks, it can cause the engine to seize up.

The timing belt is a critical component of your engine, and it should be replaced according to the manufacturer’s recommended schedule.

Conclusion

By checking these six things, you can help to keep your car engine running smoothly and efficiently. If you have any questions about checking your car engine, please consult your owner’s manual or a qualified mechanic.
