Where is the coolant temperature sensor located on the new Jetta?

The new Jetta 1.4T has two coolant temperature sensors, while the 1.6L model has one G62 sensor located near the water pump on the rear side of the engine. The water level sensor transmits the detected water level signal to the controller. The computer inside the controller compares the actual water level signal with the preset signal to determine any deviation, then issues "open" or "close" commands to the water supply electric valve based on the nature of the deviation, ensuring the container maintains the set water level. The new Jetta is a compact car produced by FAW-Volkswagen, equipped with a 1.4L L4 engine and 5-speed manual transmission, delivering maximum power of 90KW and maximum torque of 132NM.
The coolant temperature sensor of the new Jetta is usually installed in the engine compartment, near the cylinder head or next to the thermostat. I often encounter this component when repairing cars. It's connected to the cooling system pipes, responsible for detecting the coolant temperature and transmitting the signal to the dashboard. If the sensor malfunctions, the temperature gauge may fluctuate erratically, potentially causing engine overheating or even stalling. Locating it isn't complicated - open the hood and carefully inspect the cylinder block area, where you'll see a small probe with an electrical connector. Ensure the engine has cooled down before inspection to prevent burns. During routine maintenance, simply cleaning off dust can extend the sensor's lifespan. Sensor failures are more common in cold regions due to thermal stress damaging components. It's recommended to inspect connection points every six months to avoid major repairs caused by minor issues. The owner's manual contains illustrated diagrams of its location - referencing these makes identification quicker. This location is crucial for quick diagnostics, so don't delay addressing any problems.
The coolant temperature sensor of the new Jetta is located near the engine cylinder head, possibly adjacent to the thermostat or the cooling system pipe interface. Having driven for years, I've encountered inaccurate sensor readings that can affect engine performance or even trigger fault codes. Its position is designed to accurately measure temperature changes, so it's essential to check it before the engine runs. When working on it yourself, open the hood and scan around the cylinder block; the small device with one or two wire harness connections is the sensor. If the sensor is dusty or aged, the temperature display may deviate significantly, requiring timely replacement. Remember to disconnect the power and depressurize the cooling system before replacement. Knowing its location is quite useful for emergency handling on the road—for instance, when the coolant temperature warning light comes on, don't stop abruptly; find a safe spot to pull over, open the hood, and check it. It's advisable to keep a new sensor on hand for emergencies, making maintenance worry-free and cost-effective.
