The engine in your car, truck, or SUV gets hot. It is the job of the coolant temperature sensor, or CTS, to monitor the temperature of your engine and alert you when there is an issue. These alerts usually come via the dashboard lights. Most sensors in your engine don’t have a recommended service interval, you just have to replace them when they fail. If a coolant temperature sensor is not working properly, your cooling system won’t be able to do its job, and your engine will overheat, potentially causing catastrophic engine failure. If your check engine light is on, bring your vehicle to American Tire and Service, in Rio Rancho. You can schedule an appointment online, or give us a call at 505-891-8951
