Reductant Pressure Line: Removal

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Selective Catalyst Reduction (SRC)/Reductant system components are very sensitive to external contamination. Any possible measure should be taken to prevent contamination from entering the system while servicing it.

NOTE: Reductant fluid can corrode some metals. Reductant fluid must be stored and transported carefully. Reductant fluid must be disposed of according to local regulations.

NOTE: Fresh reductant fluid should be the only lubricant used in the assembly of these components. The use of any other lubricant ESPECIALLY PETROLEUM BASED LUBES may cause damage to the system.

NOTE: Reductant fluid can corrode some metals. Reductant fluid must be stored and transported carefully. Reductant fluid must be disposed of according to local regulations.

NOTE: Petroleum contamination will cause permanent damage to the reductant system.

NOTE: There are many body, chassis, frame and reductant tank configurations, it is not possible to cover all of the different configurations.

With the vehicle in NEUTRAL, position it on a hoist. Refer to: Jacking and Lifting - Overview .
