Safety First:
* Turn off the engine. This is crucial to prevent injury and fuel spills.
* Wear appropriate safety gear. This includes gloves, eye protection, and possibly a respirator, as diesel fuel can be harmful.
* Work in a well-ventilated area. Diesel fumes are dangerous.
* Have absorbent materials ready. In case of spills.
Locating the Fuel Water Separator:
The fuel water separator is usually located near the fuel tank, but its exact location can vary. Consult your Volvo 870's owner's manual for the precise location and drain procedure specific to your truck. The manual will have diagrams.
Draining the Separator (General Steps):
There are two main types of fuel water separators:
* Spin-on Filter: These are usually cylindrical and screw onto the fuel line. They typically have a small drain valve at the bottom.
1. Locate the drain valve. It's usually a small screw or valve at the bottom of the filter.
2. Position a suitable container under the drain valve to collect the water and fuel. A clear container is best so you can see the water.
3. Carefully open the drain valve. Do this slowly to prevent a sudden gush of fuel.
4. Drain the water and fuel. The water will settle at the bottom; you'll typically see a layer of water followed by fuel. Drain until only fuel comes out.
5. Tighten the drain valve securely.
6. Check for leaks.
* Bowl-Style Separator: These have a larger bowl or canister where water separates from the fuel. They usually have a drain valve or a drain plug at the bottom.
1. Locate the drain valve or plug.
2. Position a suitable container under the drain valve/plug.
3. Carefully open the drain valve or remove the drain plug. Be prepared for some fuel to come out.
4. Drain the water and fuel. Similar to the spin-on, drain until only fuel comes out.
5. Tighten the drain valve or replace the plug securely.
6. Check for leaks.
After Draining:
* Dispose of the water and fuel properly. Do not pour it on the ground. Check local regulations for proper disposal.
* Inspect the drained water. The amount and appearance of water can indicate potential problems in your fuel system. Cloudy or milky fuel indicates contamination.
Important Note: If you are uncomfortable performing this task yourself, it is best to take your Volvo 870 to a qualified mechanic. Improper draining can lead to fuel leaks and system damage. Always consult your owner's manual for the precise procedure for your specific model.
