It pairs an upgraded aluminum housing with a thermostatic element rated to open at 198°F (92°C), offering a more heat- and cold-resistant option compared with the original plastic housings that can warp, crack, or leak over time. The kit is compatible with 2002–2010 Ford Explorer V6 4.0L, 2007–2010 Explorer Sport Trac V6 4.0L, and 2002–2010 Mercury Mountaineer V6 4.0L models.\u003c\/p\u003e\n\n\u003ch3\u003eHow will an aluminum housing improve my vehicle's cooling system?\u003c\/h3\u003e\n\u003cp\u003eAn aluminum housing resists deformation and thermal cycling better than factory plastic housings, helping to reduce the risk of coolant leaks and premature failure.
