Bosch 0280130026 OE Engine Coolant Temperature Sensor | Compatible with BMW, Porsche, Saab, Volvo & More

Overview

Bosch Original Equipment Coolant Temperature Sensors provide precise coolant temperature data to the engine control unit, helping your engine operate with steady, efficient behavior across a wide range of conditions. Rather than guessing at temperature changes, the ECU receives accurate readings that support smooth engine response and balanced cooling needs in daily driving and longer trips.

Real-world use often means fluctuating temperatures, from chilly mornings to scorching afternoons. A sensor that delivers consistent feedback to the ECU can help your vehicle manage fuel delivery, ignition timing, and cooling fan activity with a calm, measured approach. This can contribute to more predictable starts, steadier idle, and easier progression through gears as you travel through different climates.

Quality, durability, and performance

• Premium performance: accurate coolant temperature information supports a long, healthy engine life when conditions change quickly.
• Accurate data for safe, efficient operation: the sensor helps the ECU adjust cooling and fuel strategies for varied driving.
• Superior engineering: robust design resists engine vibration and withstands a wide operating range from -40F to +260F.
• Optimum efficiency: OE or better quality and function aim to keep your vehicle performing at thoughtful, reliable levels.

Compatibility and fit

The sensor is designed to fit a broad set of models, including select BMWs, Porsches, Saabs, and Volvos listed in the product notes. Engine fitment can vary, so it is important to verify compatibility with your exact engine code and year using the provided fit checker.
