  1. Chapter 17 Maintaining Your Vehicle

  2. Owner's Manual • Provides valuable information about your vehicle and it's systems

  3. Fuel System • Fuel Injection System • Deliver exact amount of fuel to engine • Reduce the amount of pollution-causing gases

  4. Fuel Efficiency Depends upon: • Weight of car • Speed you drive - over 55 fuel efficiency decreased • Air resistance: keep windows closed when driving over 45 mph

  5. Fuel Efficiency Continued • Also depends upon: • Type of engine - 4 or 6 cylinder • Vehicle Design • Manual vs Automatic • Power equipment - air conditioning

  6. Know how to calculate your MPG • Used 10 gallons of fuel to drive 150 miles : 150 divided by 10 = 15MPG • You have 10 gallons of fuel. Your car delivers approximately 15 MPG in the city. How many miles should you be able to drive? = 150 miles

  7. Emission System • Catalytic Converter • Converts harmful gases into less harmful gases & water • Muffler - reduces noise. Louder sounds may indicate a hole in. Our muffler • Check emission system - CO ( may poison you), CO2, hydrocarbons, nitrogen oxides

  8. Drive Train SystemOften covered in warranty • Engine • Transmission (low fluid level may produce jerky shifting) • Clutch • Drive shaft • Differential (allows 1 wheel to turn more slowly than another) • Transaxle • Drive axles • Universal joints

  9. Ignition & Electrical System • Alternator- recharges the battery • Battery - strong acid (dangerous)- powers vehicle's starter, lights, computer assisted controls, electrical accessories. A dead battery (no sound when starting the engine)can be jump started with jumper cables - know the procedure for "jumping" a vehicle's battery

  10. Lights - headlights, taillights, back up lights, turn signals. Should be replaced immediately when defective

  11. Lubricating & Cooling Systems • Oil helps engine work efficiently by reducing friction and cleaning engine parts - warning light comes on - pull off road and shut engine

  12. Cooling System • Cools engine - mixture of antifreeze & water • Provides heat to interior of car • Radiator - connected to the engine - holds the coolant • Thermostat - controls the amount of coolant needed

  13. Maintaining Control Systems • Power Steering - makes steering easier • Master Cylinder (Brake System) - forces fluid to each wheel's brake cylinder and squeezes brake pads against the turning disk which causes the friction to slow the wheel • Parking Brake is a completely separate system - it should hold your vehicle on a hill

  14. Suspension System • Keeps tires in line according to steering • Shock absorbing

  15. Preventative Maintenance(Care given to prevent trouble later) • Includes: • Day-to-day care • Mileage-based-maintenance: Periodic servicing done after a certain number of miles - shown in manual • Warranty may be voided if maintenance schedules are not followed

  16. Tires • Belted tires - improved strength, performance and mileage • Radial tires - gives best fuel mileage - strengthens tire, improved tread mileage, & traction • Air pressure in increases when warm, lowers when cool

  17. Tires need to be rotated regularly, balanced (for even wear) and aligned (for longer life & more even wear of tire)

  18. Replace tires when the wear bar appears smooth • Always use the same tires for all 4 tires • If you want your tires to last longer then you need a higher tread-wear rating
