To check an engine, you’ll need to open the hood and take a look inside. You should start by looking for any signs of the problems listed above. If you see any of these problems, it’s important to have the car inspected by a mechanic before you buy it.

Once you’ve checked for any obvious problems, you can start to test the engine. You should start by starting the car and listening to the engine. The engine should run smoothly and quietly, without any knocking or other noises.

Next, you should check the engine’s idle speed. The idle speed should be between 600 and 1000 RPMs. If the idle speed is too high or too low, it could be a sign of a problem with the engine.

Finally, you should check the engine’s power. You can do this by driving the car and accelerating. The car should accelerate smoothly and without any hesitation. If the car hesitates or stumbles when you accelerate, it could be a sign of a problem with the engine.
