Detailed Description

Walker 270-1118 is designed to restore a reliable connection at the engine coolant temperature sensor when the original connector is cracked, corroded, or no longer locking securely. The OE-style housing and pre-terminated leads help match the factory sensor connection without modifying the mating component. This makes it a practical repair part for drivability diagnostics and electrical service on vehicles such as Ford Fusion, Ford Escape, and Ford Focus.

The connector is built with copper conductors and insulation selected for current capacity, flexibility, and resistance to underhood heat and contamination. Walker 270-1118 supports clean sensor signal transfer in areas where wiring commonly degrades, including the engine bay and other high-temperature locations. For technicians searching for a Ford Ranger coolant temperature sensor connector or a Mercury Milan engine coolant temperature sensor connector, this part provides an OE-style repair solution.
