Gates CO34738 lower engine coolant water outlet for the 2001-2010 Ford Explorer V6 4.0L and other vehicles directs coolant out of the engine and into the cooling system.

The vehicles it fits include the 2001-2010 Ford Explorer V6 4.0L, the 2005-2010 Ford Mustang V6 4.0L and the 2001-2011 Ford Ranger V6 4.0L. It is designed to fit and perform like the original. Plan on one outlet per engine. Check your own vehicle's year and engine in the "Vehicles it fits" section.
