Detailed Description

The Standard Ignition TS-561 engine coolant temperature sensor is engineered for vehicles that rely on a precise coolant temperature signal for engine management and gauge operation. This sensor is listed for 1991-1995 BMW 318i, 1991-1995 BMW 318is, 1995 BMW 318ti, 1993-1995 BMW 325i, 1993-1995 BMW 325is, 1994-1995 BMW 840Ci, 1995 BMW M3, 1991-1993 BMW M5, and 1987-1988 BMW M6 applications. On the BMW M5 and BMW M6 listings, the sensor mounts on the thermostat housing as noted in the fitment data.

Standard Ignition TS-561 is a fit-focused replacement for owners servicing BMW cooling system sensors and looking for a part that matches the original connector style and mounting layout. This part cross-references Bosch 0280130060 for the same application.

Common Issues This Sensor Can Address

• Incorrect coolant temperature readings
• Intermittent temperature signal to the engine control system
• Hard starting or poor warm-up behavior related to temperature input
• Cooling fan or gauge operation concerns tied to sensor output
• Check engine light conditions related to coolant temperature sensor faults

Installation Notes and Tips

Verify the connector shape, terminal style, and mounting location before installation. The TS-561 uses a bolt-on design with a female rectangular plug-in connector and 2 blade terminals, so the harness connection should match the original configuration. For BMW M5 and BMW M6 applications, confirm thermostat housing placement during service and inspect the surrounding cooling system components for wear or leakage while the sensor is removed.

Quality Assurance

Standard Ignition supplies replacement electrical and engine management components for service applications that require accurate fit and dependable signal transfer. Confirm the part number TS-561 against the vehicle’s original sensor specification before installation.
