NTK EF0174 Engine Coolant Temperature Sensor

NTK Engine Coolant Temperature Sensor EF0174

The NTK Engine Coolant Temperature Sensor EF0174 is built for accurate coolant temperature input to the engine management system. It is a direct-fit sensor for select GM, Hummer, Saab, Buick, and Isuzu applications, including Chevrolet Colorado and GMC Canyon models.

NTK’s technical sensor line draws on OE experience and is tested under thermal shock, vibration, and OBD verification conditions. That focus on OE-level validation helps support consistent signal output for vehicles that rely on precise coolant temperature data.

Key Features

• Blade terminal design with an oblong female connector
• 2-terminal configuration for direct sensor replacement
• No wiring harness included
• OE-style technical sensor from NTK
• Part number EF0174 for application matching and catalog lookup
• Cross-reference: this part cross-references AC Delco and Standard Motor Products applications for the same vehicle coverage

Product Details

NTK EF0174 is an engine coolant temperature sensor used to report coolant temperature to the engine control system. Accurate temperature feedback is important for fuel delivery, idle quality, cooling fan strategy, and diagnostic monitoring. This sensor is listed for 2004-2012 Chevrolet Colorado and 2004-2012 GMC Canyon, along with related coverage for Hummer H3, Hummer H3T, Chevrolet Trailblazer, GMC Envoy, Saab 9-7x, and select Isuzu models. If you are replacing a failing coolant temp sensor on a Chevrolet Colorado or GMC Canyon, EF0174 provides a cataloged OE-style replacement path.

Common Issues This Part May Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting, rough idle, or rich/lean fuel control concerns tied to temperature input
• Cooling fan operation that does not follow expected temperature data
• Diagnostic trouble codes related to engine coolant temperature sensor performance
• Intermittent sensor signal caused by age, heat cycling, or vibration

Installation Notes

Verify connector shape, terminal count, and vehicle application before installation. EF0174 uses a female oblong connector with blade terminals and does not include a wiring harness. Confirm the sensor location on the engine cooling circuit and inspect the connector for corrosion or damaged terminals before connecting the new part. For best results, compare the old sensor to the new NTK Engine Coolant Temperature Sensor EF0174 before installation.
