Hydraulic Cooling Fan Reservoir
WARNING: This page is about a different car, the 2002 Lincoln LS and 2002 Ford Thunderbird. However, it is still accessible from the selected car via links, so may be relevant.
- Reduce the fluid in the reservoir by half.
- Attach the scan tool to the vehicle.
- Start the engine and command MAX fan.
- Maintain 2500 RPM. Fluid should be observed through the reservoir returning. The internal return also functions as a relief valve; fluid must be observed through the sides of the return. If the fluid is not returning through the sides, the screen is plugged. If no or little return is observed or the fluid is returning through the pressure relief, install a new reservoir.
