Water in a diesel fuel filter is usually the result of contaminated fuel. This can be drained by opening the bottom valve or removing the plug on the bottom of the first-stage fuel filter. It is important to check for water in the fuel filter a few times a year, and to dispose of the drained fluid properly. If more than a couple of ounces of fuel have been drained, additional steps may be required.

Opening the bottom valve or removing the plug
Draining water from the fuel filter of a diesel Bolero can be done by opening the bottom valve or removing the plug on the bottom of the first-stage fuel filter. This process should be done when the Water In Fuel Indicator Light is on, and within 10 minutes of shutting down the vehicle.
To begin, locate the diesel fuel conditioner module and place a suitable container underneath the drain port. Then, rotate the drain counterclockwise until the O-ring becomes visible, allowing the module to drain for around 25 seconds or until the fuel appears clean. Afterward, rotate the drain clockwise to tighten it. Ensure that the drain valve is fully tightened to prevent air from entering the fuel system and causing drivetrain issues.
If no liquid drains, there may be a clog in the drain, and it is recommended to have the conditioner module serviced by an authorized dealer. It is also important to properly dispose of the drained fluids and filters to avoid environmental contamination.
When opening the bottom valve or removing the plug, you will be able to observe the water settling out from the diesel if drained into a transparent container. It is recommended to check and drain the system a few times a year, such as when performing other maintenance tasks like greasing or changing fluids.

Locating the diesel fuel conditioner module
The Mahindra Bolero is a diesel-powered SUV with a 1493 cc engine. It is important to regularly change the fuel filters as part of engine maintenance. The Mahindra Bolero has two fuel filters.
The first filter is mounted on top of the engine on the left-hand side. The second filter is located inside the diesel fuel conditioner module, which is mounted between the inboard side of the fuel tank and the frame rail. To locate the diesel fuel conditioner module, access the underside of your vehicle. The module is situated on the left-hand frame rail.
The diesel fuel conditioner module houses the second fuel filter, which needs to be changed regularly to maintain optimal engine performance and prevent fuel injection system damage. The module can be identified by its plastic disposable cartridge and fuel lines connected to it.
To change the filter, disconnect the fuel lines by squeezing the connector tabs and pulling them straight off. Rotate the filter counterclockwise and remove it from the bracket. Install a new filter by inserting it into the filter bracket and turning it clockwise to lock it in place. Reconnect the fuel lines and switch the ignition on and off several times to purge any trapped air from the fuel system.
It is recommended to place an absorbent cloth under the filter connectors to catch any residual fuel that may drain during the process. Regularly draining the diesel fuel conditioner module and changing the fuel filters are crucial for maintaining the health of your Mahindra Bolero's diesel engine.

Draining the fuel/water separator filters
First, locate the engine-mounted filter drain valve, which is situated on the side of the filter assembly. Turn this valve counterclockwise by a quarter turn. Next, find the underbody-mounted filter drain valve, which is located on the bottom of the filter assembly, and turn it counterclockwise by a full turn.
It is important to note that you should always fully tighten the drain valve after draining. A loose drain valve can cause air to enter the fuel system, leading to drivetrain issues and improper engine operation.
When draining the fuel/water separator filters, it is recommended to use an appropriate container to catch the drained fluid. This container can be placed under the drain port, and you should rotate the drain counterclockwise until an O-ring is visible. Allow the diesel fuel conditioner module to drain until you see clear fuel, which should take approximately 25 seconds. Then, carefully rotate the drain clockwise to tighten it.
If no liquid drains from the separator filters, there may be a clog in the drain, and it is advised to have the conditioner module serviced by an authorized dealer.

Using the correct tools
It is important to use the correct tools to ensure the task is completed safely and effectively. The tools required will depend on the specific make and model of your vehicle.
For a Chevy or GMC Duramax Diesel, you will need a 7mm socket, a 10mm socket, and a pair of needle noise. You will also require an empty container, such as a water bottle, to collect the drained fluid. It is important to use a container that can clearly show the colour of the fluid being drained, so you can distinguish between water and fuel.
For a Toyota Innova Diesel, you will need to open the bottom valve or remove the plug on the bottom of the first-stage fuel filter. This will require tools that can access and manipulate the valve or plug.
For a Ford vehicle with a 6.7L Diesel engine, you will need to locate the diesel fuel conditioner module and place an appropriate container under the drain port. An O-ring will be visible when the drain has been sufficiently loosened.
For a Ram vehicle, you will need to locate the engine-mounted filter drain valve on the side of the filter assembly and the underbody-mounted filter drain valve on the bottom of the filter assembly. These valves will need to be turned counterclockwise to open them.

Disposing of used fluids
It is important to dispose of used fluids correctly to protect the environment and your personal safety. Disposal regulations vary depending on federal, state, and local laws, so it is essential to consult with local environmental protection agencies or waste management authorities for specific guidelines and requirements. Here are some general guidelines for disposing of used fluids:
Containment
Collect used fluids such as motor oil, coolant, brake fluid, and power steering fluid in approved, sealable, leak-proof containers with tight lids. Ensure that the containers are clearly labelled as "used" to prevent accidental use or contamination.
Recycling
Many automotive shops, service stations, and recycling centres accept used motor oil, coolant, and power steering fluid for recycling. Some auto parts stores may also accept used brake fluid. Check with your local recycling centre to find out what specific fluids they can recycle.
Disposal
Dispose of used fluids at designated recycling or hazardous waste facilities to avoid environmental contamination. Never pour motor oil, coolant, or other hazardous fluids down drains or onto the ground, as they can contain chemicals that are toxic to humans and wildlife.
Assessing Quality
Check if the fuel is contaminated. If it is still usable, you might be able to mix small amounts with fresh fuel, especially in low-compression, non-precision combustion engines like lawn and garden equipment.
Storage
Store gasoline and diesel fuel in approved containers until you can properly dispose of them. Keep used fuel in a safe place, clearly marked, to avoid accidental contamination of good fuel.
Other Considerations
Some shops have waste oil burning heater systems to reclaim oil and heat their workspace. Additionally, used oil can be sold to merchants who are required to provide a mechanism for collecting and disposing of used fluids. Always handle fluids with caution and wear protective gear, such as chemical-resistant gloves, when necessary.
