Detailed Description

The TS-48 is an engine coolant temperature sender designed to trigger the coolant temperature indicator light on the dashboard when the engine reaches the calibrated temperature point. Standard Ignition uses a thermal switching design with a formed bimetallic contact arm and controlled calibration during production to maintain consistent electrical contact at the lower-temperature set point. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Vehicle-specific fitment includes 1972 Chevrolet Blazer and 1973 Chevrolet Blazer, along with 1973 Chevrolet C10 Suburban, C20 Suburban, K10 Suburban, K20 Suburban, and 1973 GMC Jimmy. The TS-48 part number is also searched as TS48 for replacement lookup and catalog matching.

Common Problems It Can Address

• Inoperative coolant temperature warning light
• Incorrect or inconsistent temperature light activation
• Faulty sender signal to the dash indicator circuit
• Electrical contact issues at the temperature switch point
• Replacement needs for aging original coolant temperature sender units

Installation Notes

Verify that the vehicle uses a coolant temperature indicator light on the dashboard before ordering. Match the connector style and blade terminal configuration to the original sender, and confirm the temperature switch specification against the application. Clean the electrical connection point before installation to help ensure a stable signal.

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 its specified temperature to support consistent operation in service.
