Additional Notes
- The Mercury Mountaineer's power steering fluid specification calls for a level maintained between the minimum and maximum marks on the reservoir, which reflects a top-off or inspection standard rather than a measured fill volume tied to a drain-and-refill service.
- Both the standard 4.0 V6 and the 4.0 V6 AWD configurations share identical power steering fluid level specifications across the 2005-2010 model years, with no differentiation in the fill range between the two drivetrain variants.
- The min-to-max range specification applies under normal use conditions for both the rear-wheel-drive and all-wheel-drive versions of the 4.0 V6 Mountaineer, meaning the level target is consistent regardless of drivetrain load differences between the two configurations.
