Motorad 1TS1059 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for OE Fitment

The MotoRad 1TS1059 engine coolant temperature sensor is built for accurate coolant temperature monitoring in select Porsche, Saab, Volvo, and Ferrari applications. It uses a 2-terminal blade design with a square female connector to match the original electrical interface on supported vehicles.

Made with approved materials for durability in extreme temperatures, this MotoRad coolant temperature sensor is manufactured to meet or exceed OEM specifications. The 1TS1059 is a direct-fit replacement for vehicles such as the Porsche 928, Volvo 740, and Saab 9000 where the original sensor uses the same connector style and terminal layout.

What It Helps Address

• Incorrect coolant temperature readings
• Hard starting or rough idle related to temperature signal errors
• Cooling fan control issues caused by a faulty sensor signal
• Check engine light conditions tied to coolant temperature input
• Driveability problems on aging Porsche, Saab, Volvo, and Ferrari cooling systems

Installation Notes and Tips

• Verify connector shape, terminal count, and female terminal style before installation.
• Confirm the vehicle application by year and model, especially on Saab 9000 and Volvo platforms with configuration notes.
• Inspect the connector and surrounding harness for corrosion or heat damage before connecting the new sensor.
• Use the correct thread sealant or sealing method only if specified by the vehicle service procedure.
• Clear diagnostic codes and confirm temperature readings after installation.
