Next, inspect the belts and hoses. Are they cracked, torn, or showing signs of aging? Don’t forget to check the oil and coolant levels. Low oil or low coolant can be a sign of unusual consumption.

Starting and Running the Engine

Start by starting the car when the engine is cold. Listen to the engine sound when starting. Strange noises, knocking, or unusual sounds can be signs of trouble. Observe the exhaust fumes.
