Bronco Engine Bay Components

  1. Battery - The battery is one of the single most important parts of your engine bay. A car battery provides power to your motor that enables the motor to function. With a dead battery, you will not be able to start your car or use any of it’s electrical functions.
  2. Starter Relay - Commonly known as a starter solenoid, the start relay switches a large electrical current to the starter to start your engine
  3. Jack - The jack for your Bronco is located in the engine bay from the factory. These are often times missing
  4. DPFE Sensor - The DPFE Sensor relays data to the Powertrain Control Module (PCM), informing it about the volume of exhaust gas passing through the system.
  5. Upper Intake Manifold - The upper intake manifold on your Bronco is usually the first thing that someone sees in your engine bay. This manifold ensures that the air coming into the engine is evenly distributed to all cylinders.
  6. Ignition Coil - Your ignition coil on your Bronco supplies voltage to your distributor which transfers the electricity to your spark plugs. It is easy to find by tracing the single spark plug wire from the distributor.
  7. Brake Booster - The brake booster is a hydraulic device that amplifies the force applied to the brake pedal, enhancing braking performance by assisting the driver in applying sufficient braking pressure.
  8. Master Cylinder - The master cylinder converts the pressure applied to the brake pedal into hydraulic pressure, enabling the transmission of braking force to the vehicle's wheel cylinders or calipers for effective braking.
  9. Cruise Control Module - A cruise control module, also known as a cruise control unit or cruise control module, is an electronic device in a vehicle's control system that manages and regulates the speed of the vehicle.
  10. Fuse Box - The fuse box is going to house most of the fuses used in your Bronco’s electrical system. 
  11. Mass Air Flow Housing - The mass air flow meter is a meter that sits in your intake tubing and reads the amount of air coming into your engine to adjust for the correct fuel.
  12. Air Cleaner Housing - The air cleaner housing is a plastic box that holds the air filter for the air intake system.
  13. Coolant/Washer Reservoir - On the Bronco, the coolant reservoir and washer reservoir are one unit, divided in the middle to keep the two liquids separate. 
  14. Radiator Cap - While it may seem like just a metal cap, the radiator cap has a special purpose. The radiator cap creates pressure to keep your cooling system at a higher PSI which increases your coolant’s boiling point. This helps your coolant absorb more heat from your engine.
  15. Windshield Wiper Motor - At the back of your Bronco engine bay is the windshield wiper motor. This motor powers the windshield wiper arms to wipe away rain on your windshield.
  16. A/C Compressor - The air conditioning compressor works as a pump to move refrigerant through your A/C system to create cold air for your Bronco’s cabin.
  17. Radiator - Your Bronco radiator is the main component of your cooling system. A radiator cools hot coolant after it has traveled through your engine using air coming through the front bumper.
  18. Upper Radiator Hose - The upper radiator hose is responsible for transferring hot coolant from your engine to the radiator to be cooled.
  19.  Alternator - The alternator in your Bronco helps to charge the battery when your car is running. While the engine is operating, the serpentine belt is spinning which turns a pulley on the alternator. This generates power that is sent to the battery to keep it fully charged.
  20. A/C Drier - The A/C drier removes moisture from the refrigerant to prevent corrosion and freezing while also filtering out contaminants. 
  21. Vacuum Reservoir Canister Tank - The vacuum reservoir canister tank on your Bronco regulates the air pressure for proper engine function.
  22. Heater Return Hose - The heater return hose transfers the hot engine coolant from the heater core back to the engine.
  23. EGR Valve - Your EGR valve helps reduce emissions by rerouting exhaust gases back into the combustion chamber.
  24. TFI Module - A TFI module is an electronic component in an ignition system that controls the timing of spark plugs, ensuring precise ignition timing for improved engine performance and fuel efficiency.
  25. Spout Connector - A spout connector is a small electrical plug or connector used to temporarily disable the ignition timing advance during engine tuning or diagnostics.
