EVIL ENERGY Aluminum Thermostat Housing Kit for Chevrolet Cruze/Sonic/Trax 1.6L–1.8L — Direct-Fit, 221°F Thermostat

EVIL ENERGY's aluminum engine coolant thermostat housing kit replaces worn housings to restore correct coolant flow and temperature control for specified Chevrolet 1.6L and 1.8L engines.

If your Cruze, Sonic or Trax is showing cooling-system warning lights, temperature swings, or coolant leaks near the thermostat area, this direct-fit replacement housing is built to match OE mounting points and restore reliable operation. The kit includes the aluminum housing and a pair of nitrile gloves for installation, and it replaces multiple GM part numbers for easy cross-referencing.

Will this thermostat housing fit my Chevy model?

Verify fitment by matching your vehicle year, engine size and existing part number. This housing is specifically manufactured for certain 1.6L and 1.8L GM four-cylinder applications and aligns with several original-equipment references.

• Compatible models: 2011–2016 Chevrolet Cruze 1.8L L4, 2016 Cruze Limited 1.8L L4
• Also fits: 2012–2018 Chevrolet Sonic 1.6L & 1.8L L4 and 2013–2018 Chevrolet Trax 1.8L L4
• Replaces OE numbers including 25192228, 55564890, 55577284, 902-033 and others

What is the construction and operating spec of this housing?

The housing is machined from aluminum for corrosion resistance and stable heat transfer. The built-in thermostat opens at approximately 221°F (105°C), matching common GM thermal requirements for these engines.

• Material: durable aluminum alloy for long service life
• Thermostat opening temperature: 221°F / 105°C
• Precision cast and drilled to align with factory coolant passages and mounting points

What performance improvements can I expect after replacement?

Installing a correct-fit thermostat housing helps the cooling system reach and maintain proper operating temperature faster and prevents premature radiator flow. While not a performance part, replacing a leaking or stuck housing reduces coolant loss, minimizes engine warm-up time issues, and avoids overheating risks caused by degraded housings.

• Stops external coolant leaks around the thermostat area
• Restores accurate thermostat operation for consistent engine temperature
• Helps prevent coolant contamination and related engine deposits

How easy is it to install and what comes in the package?

This thermostat housing is a direct-replacement design for vehicles listed above and can be installed with common hand tools by a competent DIYer or a professional mechanic. The package includes the housing and nitrile gloves; gaskets, bolts or coolant should be verified or sourced separately if your vehicle requires them.

• Package contents: 1x thermostat housing, 1x pair of nitrile gloves
• Installation: bolts and sealing surfaces match OE locations, but replacement gaskets may be necessary
• Recommended: drain coolant to below the thermostat, replace seal(s), torque bolts to factory spec

Who is this for: The EVIL ENERGY aluminum thermostat housing kit is aimed at owners and technicians working on 2011–2018 Chevrolet Cruze, Sonic and Trax models with 1.6L or 1.8L engines who need a reliable OE-style replacement. It’s appropriate for anyone repairing leaks, replacing faulty thermostat assemblies, or completing a cooling-system overhaul wanting a corrosion-resistant aluminum alternative that matches factory fitment and thermal specs.
