Detailed Description

Delphi TS10329 is an engine coolant temperature sensor designed for vehicles that rely on accurate coolant temperature input for engine management and gauge operation. Delphi draws on OE experience and supplier knowledge developed over decades of original-equipment service, and that background is reflected in the construction of this aftermarket replacement. This part cross-references Standard Ignition TX104 for the same application. Common search terms for this part include Ford Fusion coolant temperature sensor, Lincoln MKZ engine coolant temperature sensor, and Ford Ranger coolant temp sensor replacement. Delphi TS10329 is also referenced by part numbers 3L8Z 12A648-A, DY1269, TS5617, and WT5067.

What This Sensor Helps Address

• Incorrect coolant temperature readings
• Hard starting or rough running related to temperature input
• Illuminated check engine light tied to coolant temperature sensor faults
• Poor fuel control caused by inaccurate engine temperature data
• Cooling system monitoring issues on Ford Fusion, Lincoln MKZ, and Ford Ranger applications

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a female rectangle connector with 2 male blade terminals and push-on mounting, so the electrical connector and sensor seat must match the original design. Inspect the harness and connector for corrosion or damage before installing the new sensor, and confirm the cooling system is at a safe temperature before service.

Quality Assurance

Delphi builds this replacement sensor using OE heritage and application knowledge developed through long-term service to major automakers. The included instruction sheet supports correct installation and vehicle-specific verification.
