This video shows you how to install a new thermostat housing assembly from TRQ on your 2012-2020 Chevrolet Sonic (1.8L L4). The thermostat controls the flow of coolant in your vehicle’s engine. When a thermostat fails, it can lead to overheating, which will damage the engine. One sign of a faulty thermostat is a cool upper radiator hose when the engine is at full operating temperature. It’s important to replace the thermostat immediately if you suspect it is failing.

Estimated installation time for a professional technician is approximately: 1 hour 30 minutes
