Coolant Temperature Sensor OE 51274210190 for MAN Trucks & Buses

Product Description

Ensure precise thermal management and protect your commercial fleet from overheating with our premium Engine Coolant Temperature Sensor 51274210190. Engineered specifically for MAN trucks, buses, industrial D-engines, and Neoplan coaches, this high-precision sensor monitors coolant fluid heat levels and communicates real-time data directly to the Engine Control Unit (ECU).

Manufactured using a highly conductive M16 x 1.5 copper-alloy brass housing and a secure 2-pin bayonet socket, this sensor is built to survive the high-vibration, high-heat environments of heavy-duty diesel operations.

Key Performance Advantages:

• Highly Responsive NTC Thermistor: Offers rapid resistance changes relative to temperature, preventing delayed ECU feedback and cold-start issues.

• Robust Leak-Proof Body: Durable solid brass construction prevents coolant erosion and sensor-tip degradation.

• Direct OEM Drop-In: Precise thread specifications (M16 x 1.5) and 27mm spanner sizing ensure quick, modification-free replacement.

• B2B Factory Direct Pricing: Sourced straight from our sensor manufacturing facility, delivering competitive margins for global parts distributors and fleet managers.
