Changing The Fuel Filter On Your Holden Colorado Diesel

The fuel filter on your Holden Colorado is designed to remove any harmful dirt or debris from the fuel before it enters the fuel injectors. It is usually located with the fuel pump inside the fuel tank or in the fuel line between the fuel tank and the fuel rail. The replacement cost of the fuel filter depends on the location of the filter and can be anywhere between $120 and $400.

Turn off the truck and unhook the negative battery cable

To change the fuel filter on a Holden Colorado Diesel, the first step is to turn off the truck and let it sit for 30 seconds. This will stop the fuel pump from pumping. The next step is to unhook the negative battery cable to prevent the pump from trying to pump air through the lines. This step is not strictly necessary, but it is recommended as a precaution.

Unhooking the negative battery cable will ensure that the fuel pump does not activate and pump air through the lines while you are changing the fuel filter. This is important because if air is pumped through the lines, it could cause air bubbles to form in the fuel system, which can lead to performance issues and potential damage to the engine.

By taking the precaution of unhooking the negative battery cable, you can be sure that the fuel pump will not activate accidentally during the fuel filter replacement process. This will help to ensure a smooth and safe procedure, reducing the risk of complications or damage to the vehicle.

It is important to note that the battery should be reconnected once the fuel filter replacement is complete. After reconnecting the battery, turn the key to accessory mode to allow the pump to remove air from the lines for roughly 20 seconds. Then, crank the truck, check for leaks, and you should be good to go.

Get under the truck and place a drain pan under the filters

Now that the engine is off and you've disconnected the negative battery cable, it's time to get under your Holden Colorado Diesel and place a drain pan under the filters. This is an important step to catch any fuel that may leak out during the filter replacement process. Make sure you have a suitable drain pan that can hold a sufficient amount of fuel and place it directly under the filters.

The fuel filters on your Holden Colorado Diesel are located under the vehicle, and you will need to get under the truck to access them. It is important to place a drain pan under the filters to catch any fuel that may leak out during the replacement process. Fuel can be flammable and hazardous, so it is important to contain it properly.

Once you have located the filters, you will see that there are two of them. They are usually screw-on filters, so you will need a socket wrench to remove them. Before removing the filters, it is recommended to loosen the screws first and then use a little force to pull them down and remove them. This is because they are sealed tightly to prevent fuel leaks.

As you remove the filters, be careful not to spill any fuel. The drain pan will help contain the fuel, but it is important to work slowly and carefully to avoid any accidents. Make sure you are wearing appropriate safety gear, such as gloves and eye protection, to protect yourself from any fuel spills.

Now that you have placed the drain pan and are ready to start working on the filters, you can proceed to the next step of removing the old filters and installing the new ones. Remember to refer to your owner's manual or seek professional assistance if you are unsure about any part of the process.

Remove and replace the filters

To remove and replace the fuel filters on your Holden Colorado Diesel, you will need to first turn off the truck for 30 seconds to stop the fuel pump from pumping. Next, unhook the negative battery cable as a precaution to ensure the pump doesn't try to pump air through the lines.

Now, go underneath the truck and place a drain pan to catch the fuel from the filters. You will need a 1 1/4" or 27mm socket to remove both filters. Once they are unscrewed, pull down gently with a little force to get past the seals. Replace with new filters and tighten to approximately 15 ft/lbs. Reconnect the battery and turn the key to accessory mode. Allow the pump to remove air from the lines for around 20 seconds, then crank the truck and check for leaks.

It is recommended that you replace the fuel filter every 10,000-14,000 miles, or every other oil change.

Reconnect the battery and turn the key to accessory mode

Now that you've replaced the fuel filters, it's time to reconnect the battery. Ensure that the negative cable is securely attached to the battery terminal. Once that's done, you can turn the key in the ignition to accessory mode. This step is crucial as it allows the fuel pump to remove air from the lines. Let the pump run for approximately 20 seconds.

After the pump has run for the recommended time, you can try to start the engine. Crank the truck and keep an ear out for any unusual noises. Also, be sure to check for any leaks around the fuel filters. If everything seems fine, you're good to go!

It's important to note that this process assumes you've already taken the necessary steps to access the fuel filters and have drained any excess fuel. Additionally, make sure to consult your vehicle's manual or seek advice from a qualified mechanic if you're unsure about any part of the process.

Reset the fuel filter life monitor

To reset the fuel filter life monitor on a Holden Colorado Diesel, you can follow these steps:

• Turn the truck off for 30 seconds to stop the fuel pump from pumping.
• Access the fuel filter life monitor in the DIC (driver information center).
• Press and hold the check mark button on the right side of the steering wheel while viewing the fuel filter life monitor.
• Hold the button until the fuel filter life monitor resets to 100%.

Alternatively, you can try resetting the fuel filter life monitor by turning the key to the "Run" position without starting the engine. Then, access the fuel filter life monitor in the DIC and attempt to reset it. In some cases, you may need to cycle the key or restart the truck multiple times for the reset to take effect.
