TSE13 MAHLE Sensor, coolant temperature

This little guy basically controls the flow of coolant through your engine. Coolant absorbs heat from the engine, and the thermostat decides when to send that hot coolant to the radiator to be cooled down. It does this by opening and closing a valve inside, depending on how warm the engine is. It’s a pretty simple mechanical thing, but it’s vital. Think of it as the engine’s temperature regulator. When the engine first starts, it needs to warm up quickly to operate efficiently. The thermostat stays closed initially, letting the engine heat up. Once it reaches the proper operating temperature, the thermostat opens, allowing coolant to flow to the radiator. It constantly adjusts to maintain that ideal temperature, whether you're sitting in traffic or cruising on the highway. If the thermostat fails, a lot of things can go wrong. If it sticks closed, the engine will overheat—that's a big problem, can lead to serious engine damage. If it stays open, the engine will take forever to warm up, which hurts fuel economy and can wear down engine components faster. You’ll notice if it’s going bad—usually it's overheating, or the temperature gauge fluctuating wildly. Sometimes it won't be that obvious at first, but a failing thermostat will eventually cause noticeable issues. You can find a replacement pretty easily, even places like Fixparts Online have a good selection. It’s a relatively inexpensive part to replace and can save you from a much bigger headache down the road. We’ve got your back: Thermostat (MPN TSE13) is covered for 12 months!
