- BRAKESBrake BoosterUses engine vacuum to multiply your foot pressure on the brake pedal.Removal 4/5
- BRAKESBrake Master Cylinder & ReservoirConverts pedal force into hydraulic pressure and holds the brake fluid.Removal 4/5
- COOLINGCoolant ReservoirThe translucent tank where you check the coolant level.Removal 1/5
- COOLINGCooling Fan & ShroudPulls air through the radiator when the truck is not moving fast enough to do it alone.Removal 3/5
- ENGINEEngine (4.2L Essex V6)The core assembly — block, crankshaft, pistons, heads and valve train — that produces power.Removal 5/5
- ELECTRICALEngine Compartment Fuse BoxThe box of fuses and relays in the engine bay that distributes power.Removal 3/5
- FUELFuel InjectorsElectric valves that spray a measured amount of fuel for each cylinder.Removal 3/5
- FUELFuel RailThe metal tube that holds pressurised fuel and feeds each injector.Removal 3/5
- IGNITIONIgnition CoilTurns low battery voltage into the very high voltage needed to make a spark.Removal 2/5
- AIR INTAKEMass Air Flow (MAF) SensorSmall sensor that measures how much air is entering the engine.Removal 1/5
- ENGINEOil PanThe reservoir at the bottom of the engine that holds engine oil.Removal 4/5
- ELECTRICALPCM (Powertrain Control Module)The computer that reads the sensors and controls fuel, spark and emissions.Removal 3/5
- STEERINGPower Steering PumpBelt-driven pump that provides the hydraulic pressure making the wheel easy to turn.Removal 3/5
- COOLINGRadiatorThe wide finned heat exchanger at the front that cools the engine's coolant.Removal 3/5
- ACCESSORY DRIVESerpentine BeltOne long belt that drives the alternator, water pump, steering pump and A/C compressor.Removal 2/5
- IGNITIONSpark PlugsThe tips that actually make the spark inside each cylinder.Removal 2/5
- STARTING & CHARGINGStarterThe electric motor that spins the engine over when you turn the key.Removal 3/5
- STEERINGSteering GearboxTurns the rotation of the steering shaft into side-to-side movement of the steering linkage.Removal 5/5
- COOLINGThermostat & HousingTemperature-controlled valve that holds coolant in the engine until it warms up.Removal 2/5
- AIR INTAKEThrottle BodyThe valve that controls how much air the engine gets when you press the pedal.Removal 2/5
- TRANSMISSIONTransmissionSends engine power to the driveshaft, changing gear ratios as you drive.Removal 5/5
- AIR INTAKEUpper Intake ManifoldThe large casting on top of the engine that spreads air to each cylinder.Removal 3/5
- ENGINEValve CoversThe covers on top of each cylinder head that keep oil in and dirt out.Removal 3/5
- COOLINGWater PumpBelt-driven pump that keeps coolant circulating through the engine.Removal 4/5
