Where is the power steering pump located on a 1999 mercury mountaineer?

On a 1999 Mercury Mountaineer (which shares its platform and components with the Ford Explorer), the power steering pump is typically located on the front of the engine, driven directly by the crankshaft via a belt. It's usually situated near the alternator and the bottom of the engine, often towards the passenger side (right side in the US).

To be absolutely certain, you should:

* Consult your owner's manual: This is the best source for specific location information for your vehicle.

* Look at a repair manual specific to your vehicle year and engine: A Haynes or Chilton manual will have diagrams.

* Search online for a diagram: Search for "1999 Mercury Mountaineer power steering pump location" along with the engine size (e.g., 4.0L V6) for more targeted results.

Don't rely solely on general descriptions; visual confirmation is always best before attempting any repairs.
