EVIL ENERGY Thermostat Housing Kit for Ford Explorer & Mercury Mountaineer 4.0L V6 — 92°C Thermostat, Complete Assembly

EVIL ENERGY Thermostat Housing Kit assembly replaces worn housings and thermostats for 2002–2010 Ford Explorer and Mercury Mountaineer V6 4.0L engines, restoring reliable coolant flow and temperature control.

This complete thermostat housing kit includes a precision thermostat calibrated to open at 92°C (197.6°F), a durable plastic housing, a nitrile seal gasket, and gloves for installation. It matches common OEM part numbers such as 2L2Z8592AA/BA/BB and 6L2Z8592FA and is manufactured to fit model years and variants across Explorer, Explorer Sport, Explorer Sport Trac, and Mercury Mountaineer with the 4.0L V6 engine. The kit is aimed at restoring correct coolant routing and sealing where aging housings or failed thermostats have caused leaks, overheating, or poor temperature regulation.

How does this kit restore proper engine cooling?

The EVIL ENERGY kit replaces both the thermostat and its housing so coolant is directed and regulated as originally intended. The thermostat opens at the specified temperature to allow coolant into the radiator while the new housing provides a reliable, leak-resistant channel for the flow.

• Includes thermostat set to 92°C (197.6°F) for correct opening point.
• New plastic housing reduces warping and leaks from heat cycles.
• Rubber gasket ensures a tight seal where the housing meets the engine.
• Complete assembly avoids mismatched parts and simplifies replacement.

Will this part fit my vehicle model and engine?

This assembly is designed for the 4.0L V6 Ford/Mercury platforms produced between 2002 and 2010. It lists compatible vehicles explicitly to help you confirm fitment before purchase.

• Fits 2002–2010 Ford Explorer V6 4.0L (including specified Sport models).
• Compatible with 2002–2010 Mercury Mountaineer V6 4.0L models.
• Includes cross-referenced OEM numbers like 2L2Z8592AA, 2L2Z8592BA, 2L2Z8592BB, 6L2Z8592FA.
• Check year, model, and engine code against your vehicle’s VIN or factory part number.

What’s included and how does installation differ from replacing only the thermostat?

The kit ships as a single package with parts chosen to address common failure points at once. Replacing the housing with the thermostat reduces the chance of future leaks from an old or brittle housing and simplifies alignment during installation.

• Package contents: thermostat x1, rubber gasket x1, plastic housing x1, nitrile gloves x1.
• Replacing housing and thermostat together minimizes repeat labor and seal failures.
• New gasket and housing improve sealing compared to swapping only the thermostat.
• Installation typically requires basic hand tools and proper coolant draining and refilling.

Who this kit is for: technicians, DIY mechanics, and owners of Ford Explorer or Mercury Mountaineer vehicles with the 4.0L V6 who need a reliable replacement assembly for overheating signs, coolant leaks, or a faulty thermostat. If you’re restoring proper engine temperature control, eliminating a coolant leak, or upgrading a brittle OEM housing, this EVIL ENERGY kit gives the matched parts and sealing components needed for a professional repair in one purchase.
