A: The thermostat is one of the most important components of a vehicle’s cooling system. Responsible for regulating coolant flow, it makes sure that the engine doesn’t overheat and stays within the normal operating temperature.
The thermostat’s exact location can vary depending on the vehicle’s make and model, but in most vehicles, you can typically find the thermostat inside a housing near the top radiator hose. If it isn’t there, try looking near the bottom hose.
In most Chevy Cruze models, you’ll find the thermostat in a housing under the top radiator hose. In most Nissan Frontier models, you can find the thermostat located behind the lower radiator hose, which you’ll have to remove to access the thermostat.
Have you driven your vehicle recently? Because if the answer’s yes, you’ll want to turn off the engine and let it cool down before trying to access the thermostat. This is because you’ll have to unclamp your radiator hose and drain your coolant before you can get to your thermostat.
Unscrewing your radiator cap while your engine is still hot is a recipe for disaster. Hot coolant can spray out and leave you with some pretty nasty burns. For your own safety, let your engine cool down for 30 to 60 minutes before removing your radiator cap.
