Changing Diesel Fuel Filter: A Guide For Vauxhall Vivaro Vans

The fuel filter in a Vauxhall Vivaro catches impurities in the fuel that may come from the fuel tank, preventing the fuel feed system from getting dirty. In diesel cars, the filter also catches water that may be in the fuel. Diesel fuel filters should be replaced every 30,000 miles. This article will cover how to change the diesel fuel filter on a Vauxhall Vivaro.

Drain the residual water from the filter housing

To drain the residual water from the filter housing of your Vauxhall Vivaro, first, place a container underneath the filter housing. You will then need to loosen the knurled screws on the filter cover and on the lower part of the filter by turning them anticlockwise by approximately one turn to drain off the water.

You will know that the filter is drained when diesel starts to emerge from the knurled screw at the bottom. Once this happens, you can retighten the two screws.

It is recommended that you drain the fuel filter of residual water every time you change the oil and oil filter. However, if your vehicle is subjected to extreme operating conditions, such as high humidity (especially in coastal areas), extremely high or low temperatures, or substantial variations between daytime and nighttime temperatures, you should check the fuel filter at shorter intervals.

Loosen the screws on the filter cover and bottom

To loosen the screws on the filter cover and bottom of a diesel fuel filter on a Vauxhall Vivaro, first place a container underneath the filter housing to catch any residual water or fuel. Then, locate the knurled screws on the filter cover and on the lower part of the filter. Using the appropriate tool, loosen these screws by turning them approximately one turn. The filter will start to drain as soon as diesel fuel emerges from the knurled screw at the bottom. Once the filter has been drained, remember to retighten the two screws.

It is important to regularly check and drain the fuel filter, especially if your vehicle is subjected to extreme operating conditions such as high humidity (common in coastal areas), extremely high or low temperatures, or significant variations between daytime and nighttime temperatures.

If you are unsure about how to locate and loosen the screws on the filter cover and bottom, or if you are uncomfortable performing this task yourself, it is recommended that you consult a Vauxhall Authorised Repairer or a qualified mechanic. They will have the necessary knowledge and tools to safely and effectively drain and replace the fuel filter on your Vauxhall Vivaro.

Additionally, always refer to your Vauxhall Vivaro's owner's manual for specific instructions and guidelines regarding fuel filter maintenance and replacement intervals.

Retighten the screws once diesel emerges from the bottom screw

To retighten the screws once diesel emerges from the bottom screw, you must first understand why you are performing this task. The diesel fuel filter in your Vauxhall Vivaro catches impurities in the fuel that may come from the fuel tank. It prevents the injectors and other parts of the fuel feed system from getting dirty. In diesel cars, the filter also catches water that may be in the fuel. Over time, the filter accumulates particles and becomes overloaded, which can block the flow of fuel. This is why it is important to drain the filter of residual water and replace it when necessary.

To retighten the screws, first loosen them by approximately one turn to drain off the water. The filter will be drained as soon as diesel emerges from the bottom screw. Once this happens, tighten the screws again. It is important to check the fuel filter regularly, especially if your vehicle is subjected to extreme operating conditions such as high humidity, extremely high or low temperatures, or varying daytime and night-time temperatures.

The process of changing the diesel fuel filter on a Vauxhall Vivaro is relatively straightforward. The filter is located on the o/s inner wing. To access it, disconnect all pipes and heater wiring. You may need to clamp the housing in a vice to unscrew the lid, or remove the torx screw at the top. If your van has an inline hand pump in the fuel line, pump it before and after running the engine. Otherwise, simply crank the engine until it runs.

It is recommended to replace the diesel fuel filter every 30,000 miles. However, this may vary depending on the quality of fuel used and the operating conditions of the vehicle. Always refer to your Vivaro's owner's manual for specific instructions and intervals.

Disconnect all pipes and heater wiring

To disconnect all pipes and heater wiring, you will need to locate the fuel filter. In a Vauxhall Vivaro, the fuel filter can be found on the o/s inner wing. Once located, follow these steps:

• Disconnect all pipes and heater wiring: Identify the two pipes connected to the filter and carefully disconnect them. There may be a small ring that you need to press in to release the connectors.
• Remove the housing: The filter housing is held in place by a clip attached to the inner wing. Push this clip back to release the housing and lift it out.
• Open the housing: Place the housing over a bucket and remove the central bolt. This bolt usually has a Torx head, so use the appropriate tool to unscrew it. Once unscrewed, carefully split open the housing.
• Inspect the filter: With the housing open, you will be able to see the filter element. Before removing it, take note of its size and condition. If the filter is dirty or clogged, this could be the reason for changing it.
• Prepare the new filter: Ensure you have the correct size replacement filter. It is important to replace the O-rings in the housing with new ones supplied with the filter.
• Reattach the housing: After installing the new filter and replacing the O-rings, put the housing back into its clip and reconnect the two pipes. Ensure the connections are secure to prevent any leaks.

These steps will allow you to safely disconnect and reconnect the pipes and heater wiring when changing the diesel fuel filter on a Vauxhall Vivaro.

Unscrew the lid or remove the torx screw from the top

Unscrewing the lid or removing the torx screw from the top of the fuel filter housing is a crucial step in changing the diesel fuel filter on your Vauxhall Vivaro. Here's a detailed guide on how to approach this step effectively:

Unscrewing the Lid:

If your Vivaro fuel filter housing has a lid, you'll need to clamp the housing in a vice to hold it securely. Once the housing is clamped, use the appropriate tool to unscrew the lid. Make sure to apply firm but controlled force to avoid stripping the threads or damaging the lid. Place the lid aside in a safe place to access later when reassembling the filter.

Removing the Torx Screw:

If your Vivaro fuel filter housing has a torx screw at the top, you'll need a torx screwdriver or a socket that matches the size of the screw head. Insert the screwdriver or socket into the screw head and turn it counterclockwise to remove the screw. Be careful not to strip the head or over-tighten the screw, as it may be difficult to remove. Once removed, set the screw aside with the lid or in a separate safe place.

After completing this step, you will gain access to the fuel filter element. It's important to note that there are different sizes of fuel filters, so ensure you have the correct replacement size. Additionally, always refer to your Vauxhall Vivaro's owner's manual for specific instructions and safety precautions before attempting any maintenance or repairs.

Now, let's move on to the next step, which involves removing the fuel filter element and preparing the new replacement.
