When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant and refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.
- To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.
