  • Keep your engine cool-regardless if the temperatures are skyrocketing outside-by making sure your coolant temperature sensor is operating correctly. A functional coolant temperature sensor not only ensures a safer ride, but it also prevents your vehicle from using more gas than necessary. With AutoZone's great selection of coolant temperature sensors, you can easily find the perfect sensor for your exquisite ride to avoid overheating, even on the hottest of days.

    There are many ways you can tell if your engine's temps are shooting up. If your coolant temperature sensor isn't working efficiently, your Check Engine Light usually warns you of the hazardous heat that's affecting your vehicle. A defective sensor can also produce black smoke from the exhaust pipe, since more gas is being used than necessary. Other indicators of a faulty sensor include difficulty starting your ride after it has reached its typical working temperature, or if your coolant temperature gauge fluctuates irregularly. Although your ride is susceptible to extreme heat, an aftermarket coolant temperature sensor from AutoZone can subdue overheating issues, guaranteeing a safer and smoother trip to any destination.

    You can view our extensive selection of coolant temperature sensors at your local AutoZone or online. Rest assured that we stock customized sensors designed specifically for your make and model, such as a Dodge Ram coolant temp sensor and coolant temperature sensors for Ford Ranger pick-up trucks. You can benefit from Free Shipping on purchases of $75 or more, or for added convenience, you can enjoy our Same-Day Pick-up option when ordering online.
