Bosch Engine Coolant Temperature Sensor 0280130026 — OE-Grade, -40°F to 260°F Range

BOSCH 0280130026 is an OE-grade engine coolant temperature sensor that reliably reports coolant temperature to your vehicle’s engine control unit for consistent performance and protection.

This Bosch Original Equipment temperature sensor is built to replace factory units and deliver accurate engine coolant readings across extreme conditions. Designed with vibration resistance and a wide operating range from -40°F to +260°F, it supplies the ECU with the data needed for fuel management, ignition timing, and engine protection systems. The result is dependable operation, efficient fuel use, and a reduction in drivability issues related to incorrect temperature signals.

How does this sensor affect everyday driving and engine performance?

The coolant temperature sensor provides a critical input used by the engine control unit to adjust fuel delivery and ignition. When the ECU receives precise temperature data, it can optimize cold-start enrichments, improve idle stability, and prevent overheating by enabling cooling controls. A faulty sensor can cause rough idle, poor fuel economy, or false overheat warnings.

• Direct temperature feedback to the ECU for fueling and timing adjustments
• Helps manage cooling fan activation and thermostat control indirectly
• Improves cold-start behavior and idle smoothness
• Reduces risk of misdiagnosed engine trouble codes tied to temperature readings

What makes the BOSCH 0280130026 durable and reliable?

Bosch engineered this sensor to handle the harsh conditions of the engine bay, including vibration and thermal cycling. Its robust construction maintains signal integrity across a very wide temperature span so the ECU always receives usable data. The component reflects Bosch’s OE or better standards for fit, function, and longevity.

• High resistance to engine vibration for long-term stability
• Operating temperature range of -40°F to +260°F
• OE-level electrical and mechanical performance for reliable readings
• Manufactured to meet or exceed original equipment specifications

Will this sensor fit my vehicle and how do I confirm compatibility?

0280130026 fits many domestic and import models but correct fitment can depend on engine model and year. Verify compatibility using your vehicle’s year, make, model, and engine code or consult the seller’s fitment checker before ordering. If uncertain, compare the original sensor’s connector and thread size with this replacement.

• Confirmed fits include select BMW, Alfa Romeo, Porsche, Saab, Volvo, Hyundai and Volkswagen models
• Fitment variations may exist by engine type—always cross-check part numbers
• Check connector style and thread engagement to ensure proper installation
• OEM-style replacement eases install and electrical integration

How do I install or service this coolant temperature sensor?

Installation is typically straightforward: locate the sensor on the cylinder head or intake manifold, disconnect the electrical connector, remove the old sensor, and thread in the new Bosch unit to specified torque. After replacement, clear any stored fault codes and verify proper idle and temperature readings with a scan tool or gauge.

• Unplug electrical connector before removal
• Use correct torque to avoid thread or sealing damage
• Inspect harness and connector for corrosion or damage
• Clear ECU codes and verify operation after install

Who this sensor is for: If you own a compatible vehicle and need a dependable replacement that matches factory standards, the BOSCH 0280130026 delivers accuracy, durability, and OE-style fit. It’s suited for mechanics, DIY enthusiasts, and fleet operators looking to restore correct temperature feedback to the engine control system and avoid drivability or efficiency problems caused by errant temperature signals.
