Engine Health Check: Signs of a Weak Car Engine
Before learning how to check car engine health, it’s important to know if your vehicle motor needs treatment. Substandard performance or strange noises coming from the exhaust can be telltale signs that your car engine is weak. It is important to understand these factors and have your car engine checked by a professional before it gets out of hand.
Aside from the engine check light, there are a few other ways to identify signs of a weak car engine. This will help you learn easily how to check car engine health.
1. Loss of Power
How to know if your engine is healthy? Take a test drive and see if the engine RPMs drops unnaturally when accelerating hard. This and substandard performance are clear signs of engine knocking. Ultimately, you’ll know the signs of a healthy engine.
2. Unusual or excessive noises
All internal combustion engines make noise while operating, but the exhaust system muffles the noise. An overly noisy engine, or strange noises such as hissing or knocking, is clear signs of a problem with your car.
3. Reduced Consumption
It is not only poor performance that indicates problems with how to check engine health. Below-average fuel consumption is also one of the many signs that your car’s engine is weak.

Engine stalling is highly unlikely to occur in cars with automatic transmissions. Therefore, if you experience this problem or notice signs of engine knocking, it is a sign of poor maintenance.

5. How to Check Engine Health: Strange Smells
Just like unusually high-pitched or strange sounds, strange smells can also be a sign of problems with your car’s engine. These are usually caused by a breakdown in the exhaust cycle.

Follow these 7 tips on how to check car engine health:
Start with the maintenance history
The vehicle’s maintenance history records all maintenance performed on the engine and lists any problem areas or recent repairs that require attention. If your car’s logbook is missing or incomplete, you should ask yourself why. It could be that the current owner simply hasn’t kept track of its maintenance schedule, or it could be a sign that they’re intentionally hiding the car’s past to scare away potential buyers.
Even if you are satisfied that the maintenance history has been completed, you should examine it carefully and compare it to the manufacturer’s recommended maintenance schedule.
How to check car engine health: Recognizing the signs of poor maintenance
A look under the hood will quickly tell you that your engine hasn’t been properly maintained. We recommend checking your engine both with the ignition on and off so you can identify the warning signs of poor maintenance. Any holes or cracks in the engine hoses can leak fluid, so when you test drive, ask them to drive for at least 20 minutes.
They will also check for visible signs of leaks where the car was previously parked. They will also ask you to look under the car with a flashlight to make sure there are no components covered with fluid leaking from the engine.
How to Check Car Engine Health: Belts and Hoses
Check your service records to see when the belts and hoses were last replaced. If there are any cracks in the rubber, this means the parts need replacing soon.
Pay particular attention to when and how often you change your oil.
This directly affects the health and condition of the engine. Spotting Signs of Poor Maintenance If you look under the hood, you can easily spot signs that the engine has not been properly cared for. We recommend checking the engine with the ignition both on and off to identify warning signs of poor maintenance.
You need to consider the following points:
- Dirt or debris has built up on the battery terminals – This may indicate that the battery is leaking, not discharging effectively, or is ready for replacement.
- Burning odour when you turn on the ignition – The engine may have a distinct odour, but there should not be a burning odour. In this case, there may be a problem with parts such as the engine oil, transmission, or cooling system.
- Leaks – Leaks aren’t visible when you turn off your car’s engine, so you might not notice it until you hand over your money and drive a few miles.
Please drive for at least 20 minutes during your test drive.
If there are holes or cracks in the engine hose, there is a risk of fluid leakage. You should also look under the car with a flashlight to make sure no components are covered in fluids leaking from the engine.

Car Cold Start
One of the easiest ways to detect potential engine errors is to perform a cold start. This will reveal any potential problems and can tell you a lot about the overall condition of your engine. If the vehicle does not start easily, there may be a problem with the battery or starter. Or, if there’s a strange clicking sound or it feels like it’s struggling, it could mean there’s a problem with the timing belt or transmission.
You should also check the exhaust pipe for smoke.
To get a real head start, mention it to the seller or dealer when you arrange to view the car to make sure they don’t warm things up before you arrive.
Check the colour of the exhaust pipe
You can tell a lot about the condition of the engine by the colour and smell of the exhaust pipe coming out of the exhaust pipe. Before starting your test drive, turn on the ignition and walk around the back of the car.
Smoke, if present, should be grey-white and give off a characteristic gasoline or diesel odour.
If it is blue, black, or has a strong odour, it may indicate the engine is burning oil and the overall condition of the engine is poor.
Avoid any used car that produces blue, dark grey or black exhaust fumes, as this almost certainly means there is an underlying problem that could lead to expensive repair bills.
Evaluate the vehicle’s idling sound and feel
Letting the vehicle idle while looking around will give you a good idea of the overall condition of the engine.
Noise alone can tell you a lot, especially about components like the timing belt and battery.
It should be smooth, balanced and stable, without jerking or losing power, which could indicate a low battery or ignition timing problem.
Pay attention to unusual vibrations or knocking sounds, as this could mean there is a problem with the engine oil.
In addition, pay attention to the temperature gauge inside the car to see if there are signs of overheating.
Engine Health Check: When in doubt, consult an expert.
Buying a used car is a big commitment, so it’s important to get it right. If you’re not sure what’s under the hood, bring along a friend or relative who knows engine health check.
