Detailed Description

The Motorad 1TS1038 is an engine coolant temperature sensor designed for vehicles that rely on precise coolant temperature input for fuel control, idle quality, and cooling fan strategy. This part number is commonly used across Subaru Legacy and Outback models, as well as Forester, Impreza, WRX, Tribeca, and B9 Tribeca applications. It also covers 2013 Scion FR-S and 2013 Subaru BRZ fitments. This part cross-references OE-style numbers such as 22630AA140 and 74198 for the same application.

Motorad manufactures this sensor in ISO TS16949 facilities and uses materials selected for long-term performance in demanding thermal conditions. If you are replacing a faulty Subaru coolant temperature sensor, the 1TS1038 provides the connector style and terminal layout needed for a proper OE-style service replacement.

Common Issues This Part Can Help Address

• Incorrect coolant temperature readings
• Hard starting or rough cold operation caused by inaccurate sensor input
• Cooling fan control issues tied to temperature signal errors
• Check engine light conditions related to coolant temperature sensor faults
• Fuel mixture or idle quality problems linked to temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle application before installation. This sensor uses a square female connector with two blade terminals and does not include a wiring harness. Inspect the connector, wiring, and cooling system condition before replacing the sensor, and confirm the engine is cool before service.
