Detailed Description

MotoRad 1TS1045 is an engine coolant temperature sensor designed for vehicles that rely on precise coolant temperature input for engine management and gauge operation. This sensor is a practical replacement choice for Volkswagen Golf, Jetta, Passat, Cabrio, Derby, and Van applications listed in the fitment data. The square connector, female terminal layout, and 4-terminal configuration support a proper electrical connection when replacing a worn or inaccurate sensor. This part cross-references Walker Exhaust 74034 for the same application.

As a coolant temperature sensor, this component helps the vehicle’s control system read engine temperature correctly so the cooling strategy and related engine functions can operate as intended. The MotoRad 1TS1045 is also referenced under OE-style part numbers such as 6U0919501B and 357919501A for select applications.

What It Helps Address

• Incorrect coolant temperature readings
• Temperature-related warning lights or gauge irregularities
• Hard starting or drivability issues tied to faulty temperature input
• Cooling fan control problems caused by inaccurate sensor data
• Replacement needs after sensor wear, corrosion, or heat damage

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle fitment before installation. Because no wiring harness is included, inspect the existing connector and harness condition during service. Confirm the sensor location on the engine cooling circuit and compare the removed part to the new unit before final assembly. For Volkswagen Golf, Jetta, and Passat service, matching the OE connector style helps ensure a proper electrical connection.

Quality Assurance

MotoRad states that its coolant temperature sensors are produced with approved materials for durability in extreme temperatures and manufactured to meet or exceed OEM specifications in ISO TS16949 facilities. The 1TS1045 is built to support consistent performance in demanding cooling system environments.
