Power and Drive Systems
The power plant is the source of energy that maintains a vehicles movement
The drive train has many components
Power plant (Engine)
Transmission
Clutch
Drive Shaft
Differential
Transaxle
Drive Axels
Universal Joint

6. Maintaining the Power Systems
Ignition and Electrical Systems
The ignition system sets off the combustion in your engine and runs the lights, controls, and accessories
Alternator
The alternator generates an electrical current that recharges the battery
Battery
A vehicle’s starter, lights, computer assisted controls, and other electrical accessories depend on the electrical powered stored in the battery

10. Under hood checks

11. Maintaining the Power Systems
Lubricating and Cooling System
Lubricating System
Lubricants such as oil, help the engine operate efficiently by reducing friction, carrying away engine heat, and cleansing engine parts
Cooling System
The cooling system provides a way for your vehicle to stay cool, and provides a source of heat for your vehicle’s interior in cold weather

12. How to check the engine oil

16. Car's Cooling System

19. Maintaining the Power Systems
Fuel and Emissions Systems
Fuel System
Lubricants such as oil, help the engine operate efficiently by reducing friction, carrying away engine heat, and cleansing engine parts
Emission System
Exhaust recalculates unburned fuel back into the combustion process for greater efficiency, Then the catalytic converter converts harmful gases into less harmful gases and water

21. Fuel System

22. Maintaining the Control Systems
Steering Systems
Includes steering wheel, steering column, steering gear, and connections to front wheel
Common indications of problems include:
Play in the steering wheel
Steering difficulty, even though tires are properly inflated
Shimming or wobbling, or shaking or pulling to one side
Squealing sounds when you make turns

24. Maintaining the Control Systems

Some brake problems may include:
Spongy feel in the brake pedal
Pulling to one side when stopping with dry brakes
Grabbing or uneven brake action
Squealing or chattering noises in the brakes
A need to push the brake harder in order to stop the vehicle

28. Brake System

29. Maintaining the Control Systems
Tires
Lifelines to the road
Construction
Made of rubber reinforced with layers of material under the tread
Inflation and Tread
Maintain the manufacturer’s recommended air pressure in the tires at all times
Rotation and Alignment
Rotate your tires regularly to promote longer tire life
Replacing Tires
A smooth wear bar will appear when it is time to replace your tires

30. Tire Tread Pattern

31. Preventive Maintenance
Routine Checks
Before You Start the Engine
Look for signs of fluid leaks under the vehicle
After You Start the Engine
Check gauges, warning lights, & fuel supply
While Driving
Notice any unusual instrument panel readings, out of the ordinary sounds, odors, or vibrations

32. Preventive Maintenance
Routine Checks
At a Fuel Stop
Oil level
Windshield washer fluid
Clean windshield
Check windshield wipers
Check tires

33. Checking the Oil Level

37. Preventive Maintenance
Selecting a Qualified Technician
It is important that you find a reliable service and repair location staffed with trained and certified technicians and mechanics
Scheduled Service
Your owner’s manual shows the recommended maintenance intervals for you to follow
