EVIL ENERGY Thermostat Housing Kit — Ford Explorer & Mercury Mountaineer 4.0L (2002–2010), 197.6°F Thermostat & Gasket

EVIL ENERGY Thermostat Housing Kit Assembly (2L2Z8592AA compatible) is a complete replacement set that restores reliable coolant flow and temperature control for 2002–2010 Ford Explorer and Mercury Mountaineer 4.0L V6 engines.

If your vehicle is showing signs of overheating, slow warm-up, or coolant leakage around the thermostat area, this EVIL ENERGY assembly provides the direct-fit components needed to return the cooling system to proper operation. The kit matches several original equipment numbers and includes the thermostat calibrated to open at 197.6°F (92°C), a molded plastic housing, a nitrile seal, and protective gloves for a cleaner swap. It is designed to replace worn housings that crack, leak, or allow improper thermostat seating.

Which model years and engines will accept this thermostat housing kit?

This assembly is engineered for 4.0L V6 engines in specific Ford/Mercury vehicles across the 2002–2010 model years. Verify fitment by cross-referencing the listed OE part numbers or checking your vehicle’s existing housing before ordering.

• Compatible models: 2002–2010 Ford Explorer (including 2002–2003 Explorer Sport and 2007–2010 Explorer Sport Trac)

• OE reference numbers matched: 2L2Z8592AA, 2L2Z8592BA, 2L2Z8592BB, 6L2Z8592FA

How does the kit help stabilize engine temperature?

The thermostat included is calibrated to begin opening at 197.6°F (92°C), allowing coolant to circulate to the radiator only when needed. Proper thermostat operation promotes consistent engine temperature, helping reduce thermal stress and potential deposit buildup in the cooling passages.

• Thermostat opening temp: 197.6°F / 92°C for predictable regulation
• New housing ensures correct thermostat seating and reduces leak paths
• Restored coolant flow reduces uneven heating and potential hot spots

What exactly is included and what should I expect during installation?

The kit contains the parts required for a single straightforward replacement: a sealed thermostat, a molded plastic housing with mating surfaces, a nitrile rubber gasket, and a pair of disposable gloves. Installation is a standard do-it-yourself job for mechanically inclined owners, but replacing coolant and proper torqueing of fasteners are important for a long-lasting repair.

• Package: thermostat x1, rubber gasket x1, plastic housing x1, nitrile gloves x1
• Recommended: drain a portion of coolant, clean mating surfaces, replace gasket for a leak-free seal
• Tools typically required: basic hand tools, coolant catch container, torque wrench for correct bolt specs
