This HELLA coolant temperature sensor, part number 6PT 009 309-251, is designed to provide precise measurements of your engine's coolant temperature. Accurate temperature readings are crucial for the proper functioning of your vehicle's engine management system, influencing fuel injection, ignition timing, and fan operation. By reliably monitoring the coolant temperature, this sensor helps prevent overheating and ensures your engine operates within its optimal temperature range. This contributes to improved fuel efficiency, reduced emissions, and extended engine life. The sensor is built to meet or exceed original equipment specifications for a direct fit and reliable performance. Proper functioning of the coolant temperature sensor is vital for diagnostics. It sends critical data to the engine control unit (ECU), allowing it to adjust engine parameters accordingly. A faulty sensor can lead to various drivability issues, including poor starting, rough idling, and illuminated check engine lights.

  • Direct fit replacement for original equipment.
