Aluminum Coolant Thermostat & Housing Assembly Compatible with Chevy

In this review of the Aluminum Coolant Thermostat and Housing Assembly, the reviewer finds it best suited for owners of Chevrolet Cruze, Sonic, and Trax models who need a direct replacement with improved durability. The unit ships complete with a thermostat, housing cover, temperature sensor and gasket, and the standout reason to buy is the full aluminum construction that replaces plastic housings for a more robust long-term solution while maintaining OE-style fitment.

Key Features

• Vehicle Fitment: Fits Chevrolet Cruze 2011-2016, Cruze Limited 2016, Sonic 2012-2018, and Trax 2013-2020 so buyers can expect a direct-replace part for those engine layouts.
• Full Aluminium Construction: The metal housing is more resistant to heat and warping than many plastic alternatives, offering better long-term mechanical integrity.
• Complete Kit: Ships with the thermostat, housing cover, temp sensor with clip, and gasket O-ring so installation can be completed without sourcing extra parts.
• Built-in Sensor: The included 2-pin temperature sensor integrates into the housing to restore coolant temperature feedback without additional wiring work.
• Specified Temperature: The thermostat is rated to open at about 221 degrees F, matching expected operating thresholds for these GM engines.
• Warranty: Backed by a one-year unlimited-mileage guarantee, providing buyers reasonable assurance against early failures.

Who It's For

This assembly is best for DIYers and independent shops replacing a failed thermostat housing on supported Chevrolet Cruze, Sonic, and Trax models who want a sturdier metal replacement and the convenience of a complete kit. Owners looking to eliminate recurring failures from brittle plastic housings will appreciate the aluminium body and included sensor.

It is less suitable for vehicles outside the listed fitment or for owners who need an OEM-branded part number for warranty or dealership service records. Also, if long-term leak prevention is the primary concern, installers should ensure correct torque and fresh sealing surfaces since some users have reported leakage after several months.

• Complete contents make installation straightforward, including thermostat, sensor and gasket.
• Good vehicle-specific fitment ensures correct alignment and mounting for the listed Chevy models.

Cons
