What is the main function of a thermostat?

The thermostat's main job is to control the flow of coolant through your engine. It stays closed when the engine is cold to help it warm up faster, and then opens up as the engine reaches its normal operating temperature to allow coolant to circulate and prevent overheating.

Why is it important to replace a thermostat?

A faulty thermostat can cause your engine to overheat or run too cool, both of which can lead to poor fuel economy, increased emissions, and potential engine damage. Replacing it ensures your engine operates within its designed temperature range.

Does this thermostat come with a gasket?

This thermostat (Part #33428) is sold individually. It is recommended to check the manufacturer's installation instructions or consult with a technician to see if a gasket is required for your specific vehicle and if it is included or needs to be purchased separately.
