steps to check a car engine: 
1. check the oil level: pull out the dipstick, wipe it off, insert it back into the engine, and pull it out again. the oil level should be at maximum. 
2. check the oil color: the oil should be golden brown or light tan; black oil means it is time to change the oil filter. 
3. check the radiator fluid: open the coolant reservoir and check the fluid level. 
4. check the battery: make sure all the cables are connected securely and that there is no corrosion. 
5. check the spark plugs: examine each spark plug for spark strength, correct gap setting and wear. 
6. check the brake pads: look for wear and tear or any foreign objects caught in the brake pad. 
7. check the hoses: make sure all the hoses are secure and well connected.
