Standard Ignition TS-131 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

Standard Ignition TS-131 is an engine coolant temperature sender built for vehicles with gauges that rely on accurate temperature signal input. It uses a bolt-on, single-stud design with a 1/8-27 thread size for direct replacement in supported applications.

Compatible With 1981-1983 Plymouth Reliant, 1982-1983 Chrysler Imperial, and other listed Chrysler, Dodge, and Plymouth gauge-equipped applications, this sender is calibrated to switch at its specified temperature point. Standard Ignition TS-131 is also cross-referenced to Four Seasons 37924 for the same application.

Key Features

• Bolt-on attachment method for straightforward mounting
• Male round connector with one terminal and one connector cavity
• Single stud terminal design
• 1/8-27 thread size
• Factory-calibrated and tested for switch actuation at the specified temperature
• Uses a formed bimetal contact arm for precise electrical switching
• Built with high-grade materials for service-professional use

Detailed Description

The TS-131 engine coolant temperature sender is engineered to provide a reliable temperature signal for gauge-equipped vehicles. Standard Ignition uses a thermal switching design with a wax and bimetal-based actuation system, then calibrates each unit during production to confirm proper electrical contact at the lower-temperature set point. That makes this sender a practical choice when replacing a worn or inaccurate coolant temperature switch in Chrysler, Dodge, and Plymouth applications.

Fits 1982-1983 Chrysler Imperial, N/A; Fits 1982-1983 Chrysler LeBaron, N/A; Fits 1982-1983 Chrysler New Yorker, N/A; Fits 1983 Dodge 600, N/A; Fits 1982-1983 Dodge Aries, N/A; Fits 1983 Dodge Charger, N/A; Fits 1982-1983 Dodge Dart, N/A; Fits 1981-1983 Plymouth Reliant, N/A; Fits 1983 Plymouth Turismo, N/A. Standard Ignition TS-131 is a direct-fit option for these gauge applications when the original sender uses the same thread and connector style.

What It Helps Address

• Inaccurate or erratic coolant temperature gauge readings
• No gauge response from a failed temperature sender
• Intermittent electrical contact at the sender terminal
• Replacement needs for aging gauge-equipped cooling system components
• Temperature signal issues in listed Chrysler, Dodge, and Plymouth models

Installation Notes and Tips

Verify the thread size, connector style, and gauge application before installation. This sender uses a male round connector, one stud terminal, and a 1/8-27 thread, so matching the original configuration is important for proper fitment. Clean the mounting surface and inspect the harness connector before installing the new unit.

Quality Assurance

Standard Ignition manufactures this sender with complete quality control from component selection through final testing. Each unit is calibrated and checked for switch actuation at the specified temperature to support consistent performance in service.
