Standard Ignition TS-357 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Gauge and Light Applications

Standard Ignition TS-357 is an engine coolant temperature sender built for vehicles that use a dashboard gauge or coolant temperature indicator light. It uses a calibrated thermal design with a formed bimetal contact arm and factory-set actuation points for consistent electrical signaling.

For Ford, Lincoln, and Mercury applications, TS-357 supports accurate coolant temperature reporting in systems that rely on a sender rather than a full sensor module. The TS-357 part number is also commonly searched for OE-style replacement needs on Ford Escape, Mustang, and Town Car applications.

Key Features

• Engine coolant temperature sender for gauge and indicator-light systems
• Standard Ignition TS-357 replacement part number
• Bolt-on attachment method with one square female plug-in connector
• 2 male blade terminals for electrical connection
• Factory-calibrated thermal actuation for specified temperature response
• Built with high-grade materials and a robust thermal switch design

Detailed Product Overview

This coolant temperature sender is designed to transfer the temperature signal needed by the instrument cluster or warning light circuit. The internal thermal switch uses wax and bimetallic movement to create a precise snap-action contact at the specified lower-temperature set point. Standard Ignition calibrates and tests each unit during production to confirm switch actuation at the intended temperature.

TS-357 is a direct-fit style replacement for select Ford, Lincoln, and Mercury vehicles, including 2001-2008 Ford Escape, 1997 Ford Mustang, and 1996-1998 Lincoln Town Car applications. This part cross-references Four Seasons 37462 for the same application.

What It Helps Fix

• Inaccurate or erratic coolant temperature gauge readings
• Dashboard temperature warning light that does not respond correctly
• Failed sender causing no signal to the gauge circuit
• Intermittent temperature indication from worn thermal contacts
• Replacement needs on Ford Escape, Mustang, Continental, and Town Car applications
