The injectors in your diesel engine provide fuel to the cylinders via the fuel pump. The number of injectors will vary depending on your engine. Each cylinder has an injector. These are located directly under the valve cover. Aftermarket injectors are available to increase the horsepower and response of your diesel engine. You will need to verify the make, model and year of your vehicle to ensure the correct injectors are purchased.

Instructions

  1. 1

    Open the bonnet by pulling the release lever inside the vehicle and prop it up.

  2. 2

    Locate the valve cover on the top of the engine. It is attached to the engine with bolts. Remove these bolts with a ratchet and socket. Remove the cover from the engine and set it aside.

  3. 3

    Remove the fuel supply lines for each injector with a wrench. These lines are usually gold in colour. Each injector has its own supply line.

  4. 4

    Unscrew the two bolts that secure the injector hold-down brace into position with a ratchet and socket. Remove the hold-down and set it aside.

  5. 5

    Pull the injector out of the engine with a pair of pliers.

  6. 6

    Install the new injector by pressing it into the engine. Reinstall the injector hold-down bracket. Align the holes and install the bolts. Tighten the bolts with the ratchet and socket.

  7. 7

    Repeat these steps to replace the remaining injectors. Take each injector out one at a time to avoid confusion.

  8. 8

    Reinstall the fuel supply lines and tighten the nuts with the wrench.

  9. 9

    Place the valve cover back onto the engine. Install the bolts and tighten them with the ratchet and socket.

  10. 10

    Start the engine and check for any leaks.
