When we recently tested the 2L5Z-8592-BB Aluminum Thermostat Housing Assembly, we were impressed by its exceptional build quality. Made specifically for Ford Explorer (2000-2001), Explorer Sport Trac (2001-2005), Ranger (2001-2011), Mazda B4000 (2001-2008), and Mercury Mountaineer (2000-2001), this RH165 component delivers reliable performance where it matters most.

The aluminum construction offers significant advantages over plastic housings, particularly in durability and heat dissipation.
