Engine Coolant Temperature Sensor for GM Applications

The Delphi TS10253 engine coolant temperature sensor is built for vehicles that rely on accurate coolant temperature feedback for engine management. It uses a threaded nut mounting style, a female oval connector, and a 2-terminal blade design to support a secure electrical connection.

Compatible With select Buick, Chevrolet, Cadillac, GMC, Pontiac, Saturn, and Saab models, including Buick Enclave, Chevrolet Traverse, and Cadillac CTS applications. Delphi’s OE heritage and supplier experience are reflected in the sensor design and materials used in this aftermarket replacement.

Key Features

• Engine coolant temperature sensor for temperature signal input to the engine control system
• Delphi part number TS10253
• Blade terminals with 2 terminal positions
• 1 female oval connector
• Threaded nut mounting type for secure installation
• Wiring harness not included
• Package contents: engine coolant temperature sensor and instruction sheet

Detailed Description

The Delphi TS10253 is an engine coolant temperature sensor designed for direct replacement in a wide range of GM and related vehicles. It is used in applications such as the 2008-2017 Buick Enclave, 2009-2017 Chevrolet Traverse, and 2004-2011 Cadillac CTS, along with additional fitments across Chevrolet, GMC, Pontiac, Saturn, and Saab models. This part number, TS10253, is also cross-referenced to Standard Ignition TX133 for the same application.

Delphi draws on OE experience and supplier knowledge to produce aftermarket parts that follow original equipment design expectations. The sensor’s oval connector shape, female connector gender, and male blade terminals help maintain proper electrical contact in the cooling system circuit.

What It Helps Address

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough running related to temperature signal errors
• Cooling fan operation issues caused by faulty temperature input
• Check engine light conditions tied to coolant temperature sensor faults
• Driveability problems after sensor wear, corrosion, or connector damage

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a threaded nut mount and does not include a wiring harness, so inspect the vehicle connector and wiring for corrosion, looseness, or heat damage before fitting the new part. Follow the included instruction sheet and confirm the cooling system is at a safe temperature before service.

Quality Assurance

Delphi builds this replacement sensor with OE heritage and application knowledge developed through long-term supplier experience with major automakers. That background supports consistent fitment and electrical performance across the listed vehicle applications.
