Standard Ignition TS-302 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Ford and Mercury

Standard Ignition TS-302 is an engine coolant temperature sender built for vehicles that use a gauge-based cooling system signal. It is a direct-fit style replacement for select Ford Contour and Mercury Mystique applications, with a bolt-on design and a single rectangular plug-in connector.

Built with a formed bimetal contact arm and factory-calibrated actuation points, this TS-302 sender is made to deliver consistent electrical switching at the specified temperature. Standard Ignition also uses controlled manufacturing and testing to verify switch operation before the part leaves production.

Key Features

• Engine coolant temperature sender for gauge-equipped applications
• Bolt-on attachment method for straightforward mounting
• 1 male rectangular plug-in connector
• 2 male blade terminals
• Factory-calibrated and tested for switch actuation at the specified temperature
• Uses a bimetal contact arm for precise thermal switching
• Standard Ignition TS-302 replacement part number

Detailed Description

Standard Ignition TS-302 is designed for cooling-system temperature signaling where the vehicle relies on a sender for the gauge circuit. It is listed for 1998 Ford Contour, 1995-1997 Ford Contour, and 1995-1997 Mercury Mystique, including applications noted as fits engines with gauges. If you are searching for a Ford Contour coolant temperature sender or a Mercury Mystique temperature sender, TS-302 is the direct reference to check.

The sender uses thermal switching components calibrated to close at the lower-temperature set point specified for the application. That makes it a practical choice when replacing a worn or inaccurate coolant temperature sender that affects gauge readings. Cross-reference part numbers include 8373 and TS302T for the same application.

What It Helps Solve

• Inaccurate or erratic coolant temperature gauge readings
• No gauge response from the engine coolant temperature sender circuit
• Temperature signal issues on gauge-equipped Ford Contour models
• Temperature signal issues on gauge-equipped Mercury Mystique models
• Replacement needs for a worn thermal sender with a failing contact mechanism

Installation Notes and Tips

Verify the connector style, terminal count, and vehicle application before installation. This TS-302 uses a male rectangular plug-in connector with two male blade terminals and a bolt-on mounting style. Confirm the vehicle is equipped with the gauge-based setup listed for Ford Contour and Mercury Mystique before ordering.

For best results, inspect the connector for corrosion or looseness and compare the old sender’s mounting and terminal layout to the new part before installation. Standard Ignition TS-302 is intended for direct replacement in the listed applications.

Quality Assurance

Standard Ignition controls production from component selection through finished part testing. Each unit is calibrated and tested to confirm actuation at the specified temperature, supporting consistent performance in the cooling system signal circuit.
