Daewoo Lanos: Replacing Fuel Filter, Step-By-Step Guide

Changing the fuel filter on a Daewoo Lanos can be a challenging task. The fuel filter is located on the firewall in the back of the engine compartment, and it is recommended to replace it every 45,000 km or every 3 years. While there are various fuel filters available in the market, such as ACDelco, Bosch, and WIX, changing the fuel filter requires careful handling of the plastic disconnect on the side leading from the fuel tank, which can be brittle and easily break. It is also important to ensure that the battery negative terminal is disconnected before working on the fuel system to avoid any safety hazards.

Fuel filter location

The fuel filter for a Daewoo Lanos is located on the firewall in the back of the engine compartment. It will look like a metal can, similar to a soda can, with two metal pipes coming out of each end. These pipes connect to the fuel lines. One pipe comes from the driver's side and goes down and under the car, while the other goes to the passenger side and loops around towards the engine.

To change the fuel filter, you will need to disconnect the fuel lines. A fuel line disconnect tool can be used for this, but be careful as the plastic disconnect on the side leading from the fuel tank can be brittle and break easily. There may not be enough clearance to use the disconnect tool. In this case, you may need to cut the fuel tubing at the body of the filter with a hacksaw. Once the fuel lines are disconnected, you can pull out the old filter and insert the new one.

Fuel line disconnect tool

Changing the fuel filter on a Daewoo Lanos can be a tricky task. A fuel line disconnect tool is a must-have for this job, and it's important to note that Daewoo likely uses the same type of tool as GM vehicles. This tool is designed to be clamped around the tube of the fuel filter, and then pushed up into the fitting on the fuel line. Its purpose is to retract the four retaining fingers in the fuel line fitting, which are spring-loaded radially. These fingers tightly grip a flange on the filter tubing.

When using the fuel line disconnect tool, it is crucial to exercise caution as the plastic disconnect on the side leading from the fuel tank can be brittle and prone to breakage. In some cases, there may not be enough clearance to use the tool effectively. If this is the case, an alternative method is to cut the fuel tubing at the body of the filter with a hacksaw, allowing for a better view of the components and potentially enabling the use of the disconnect tool.

A plastic sleeve, available in kits at auto parts stores for around $10, can be used to retract the retaining fingers. Once retracted, the end of the filter tube can be pulled out of the fuel line fitting. This may require some force, and it is important to be prepared for a challenging task.

Fuel tubing

To change the fuel filter on a Daewoo Lanos, you will need to access the fuel tubing. Here is some detailed information on how to do this:

The fuel filter on a Daewoo Lanos is located on the firewall at the back of the engine compartment. It will look like a metal can with two metal pipes coming out of each end, connecting to the fuel lines. One pipe comes from the driver's side and goes down and under the car, while the other goes to the passenger side and loops towards the engine.

Before starting, it is recommended to disconnect the battery negative terminal for safety. Then, to access the fuel tubing, you may need a fuel line disconnect tool, as the plastic disconnect on the side leading from the fuel tank can be brittle and break easily. Clamp the tool around the tube of the fuel filter and push it into the fitting on the fuel line to retract the retaining fingers. If you don't have enough clearance to use the tool, you may need to cut the fuel tubing at the body of the filter with a hacksaw. Be careful and take the necessary precautions when performing this step. Once the tubing is cut, you can try using the disconnect tool again.

After cutting the tubing, use a plastic sleeve (available at auto parts stores) to retract the retaining fingers and pull the end of the filter tube out of the fuel line fitting. You may need to use some force to remove it completely. With the retaining fingers retracted, you can now detach the fuel tubing from the fuel filter.

Remember to have the necessary tools and safety equipment before starting, and always refer to a trusted repair guide or mechanic if you are unsure about any steps.

Retaining fingers

The retaining fingers on the fuel filter of a Daewoo Lanos are spring-loaded radially. There are four of them, and they tightly grip a flange on the filter tubing. To remove the fuel filter, a fuel line disconnect tool can be used to retract the retaining fingers. This is done by clamping the tool around the tube of the fuel filter and pushing it up into the fitting on the fuel line.

Alternatively, a hacksaw can be used to cut the fuel tubing at the body of the filter. This will allow you to see what's going on and possibly use the disconnect tool to retract the retaining fingers. Once the retaining fingers are retracted, you can pull the end of the filter tube out of the fuel line fitting.

Fuel filter replacement schedule

It is recommended that you replace the fuel filter on your Daewoo Lanos every 45,000 km or every three years. This is applicable to both the Lanos Saloon (from February 1997 onwards) and the Lanos Hatchback (from May 1997 onwards).

Additionally, it is advised to replace the fuel filter every 15,000 km or annually. This is also applicable to both the Lanos Saloon and Lanos Hatchback models mentioned above.

By adhering to this replacement schedule, you can help maintain the optimal performance and fuel efficiency of your Daewoo Lanos.
