• Helps engine maintain normal operating temperature


• Controls flow of coolant from radiator to engine


• Replace quickly when malfunctioning

Your vehicle relies on coolant to help the engine remain cool and at the right operating temperature. Many parts help coolant perform its job, and the coolant thermostat is one of the most important ones. When the thermostat stops working correctly, it needs to be replaced immediately. This INFINITI Engine Coolant Thermostat Kit has what you need to get the job done right.

You can usually find the coolant thermostat between the engine and radiator. It acts as a gate and blocks or allows the flow of coolant between the two parts. Thermostats have a preset temperature that regulates when they open. As things warm up, the coolant thermostat opens, allowing the coolant to circulate through your engine. When your engine reaches its regular operating temperature, the coolant returns to the radiator, where it cools down before once again making its way to the engine. It's imperative that the coolant thermostat opens and closes at the right moment so your engine can stay at the optimal temperature.

Your coolant thermostat is a critical part of your INFINITI's cooling system, and you're likely to notice when it begins to fail. A malfunctioning thermostat normally means it's stuck open or closed. Some signs of a bad coolant thermostat are erratic temperature changes, an overheating engine, and coolant leaks. If you experience any of these symptoms, have your INFINITI checked out immediately.

A bad coolant thermostat can lead to long-term engine damage, so it's crucial you get a replacement as fast as possible. With an Engine Coolant Thermostat Kit made to fit your INFINITI and the correct tools, replacing the thermostat by yourself can be relatively simple. Don't forget to let your engine cool completely before starting the task. If you don't feel comfortable removing the thermostat and installing your replacement Engine Coolant Thermostat Kit, you can leave it to the pros and bring your vehicle to an INFINITI service center.
