Detailed Description

Motorad 1TS1033 is an OE-style coolant temperature sensor for vehicles that rely on precise coolant temperature data for engine management, gauge operation, and cooling system control. It is engineered to meet or exceed OEM specifications and is suited for applications such as 2008-2017 Buick Enclave, 2009-2017 Chevrolet Traverse, 2007-2016 GMC Acadia, 2004-2011 Cadillac CTS, and 2006-2009 Saab 9-3. This part cross-references GM service numbers 2131581 and 2134777 for the same application.

What It Helps Address

• Incorrect coolant temperature readings
• Illuminated engine warning lights related to temperature sensing
• Cooling fan control issues caused by faulty temperature input
• Rough engine operation tied to inaccurate coolant data
• Hard starting or drivability concerns linked to sensor failure

Installation Notes and Tips

Verify connector shape, terminal count, and sensor location before installation. This sensor uses a female square connector with blade terminals and does not include a wiring harness, so the existing vehicle connector must match the OE-style configuration. Confirm the exact application by year, make, and model before ordering, especially on GM platforms such as Chevrolet Malibu, Pontiac G6, and Buick LaCrosse.

Quality Assurance

Motorad manufactures this coolant temperature sensor in ISO TS16949 facilities and uses approved materials selected for durability across extreme operating temperatures. The design is intended to meet or exceed OEM specifications for consistent fit and function.
