Engine Coolant Temperature Sender for Ford Escort and Mercury Tracer

Standard Ignition TS-300 is an engine coolant temperature sender built for vehicles with gauge-equipped cooling systems. It uses a bolt-on attachment, a male round connector, and a 3/8-18 thread size for a direct-style service replacement on select Ford and Mercury applications.

Key Features

  • Engine coolant temperature sender for gauge applications
  • Bolt-on attachment method
  • Male round connector with stud terminal
  • 3/8-18 thread size
  • Factory-calibrated and tested for switch actuation at the specified temperature
  • Built with a formed bimetallic contact arm and precision thermal switching design

Product Details

The Standard Ignition TS-300 is engineered for accurate coolant temperature signal transfer in vehicles that rely on a sender for the dash gauge circuit. Standard Ignition uses calibrated thermal-switch construction, with controlled material expansion and contact movement to help deliver consistent electrical response at the target temperature. As an OE-focused manufacturer, Standard Ignition maintains quality control from component selection through final testing. This part cross-references AP Exhaust 8391 for the same application.

Vehicle Fitment

  • Fits 1995-1996 Ford Escort, N/A. Fits engines with gauges.
  • Fits 1995-1996 Mercury Tracer, N/A. Fits engines with gauges.
  • Fits 1991-1993 Mercury Tracer, N/A. Fits engines with gauges.

Common Symptoms This Part May Address

  • Inaccurate or erratic temperature gauge readings
  • Gauge needle that stays low, high, or does not respond normally
  • Faulty coolant temperature signal to the instrument cluster
  • Temperature sender failure on gauge-equipped cooling systems

Installation Notes

Confirm the connector style, thread size, and gauge-equipped application before installation. Clean the mounting surface and verify the electrical connection is secure after tightening the sender to the specified location. For best results, compare the removed part to Standard Ignition TS-300 before service on Ford Escort or Mercury Tracer models.

Quality Assurance

Standard Ignition calibrates and tests each thermal switch during production to confirm actuation at the specified temperature. The brand’s OE manufacturing background supports consistent fit, form, and electrical performance for service replacement use.
