Standard Ignition TS-168 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender for Gauge Applications

Standard Ignition TS-168 is an engine coolant temperature sender built for vehicles that use a dash gauge. It uses a calibrated thermal design with a formed bimetal contact arm and factory-set actuation points to deliver a direct electrical signal for temperature monitoring.

Key Features

• Female plug-in connector with 2 blade terminals
• Calibrated and tested for specified switch actuation temperature
• Thermal switch design with wax and bimetallic contact movement
• Built with robust materials for service use
• OE-style replacement for gauge-equipped cooling system applications

Detailed Description

The Standard Ignition TS-168 engine coolant temperature sender is designed for vehicles that rely on a temperature gauge rather than an electronic cluster input. Its thermal switching design uses controlled expansion to activate the electrical contact at the specified lower-temperature set point, helping provide consistent signal output to the gauge circuit. This part cross-references Four Seasons 85002 for the same application. Common fitment includes 1984-1991 Chevrolet Corsica, 1986-1988 Chevrolet S10, 1987-1988 Chevrolet S10 Blazer, and 1984-1988 Pontiac Fiero, along with additional Buick, Cadillac, GMC, Oldsmobile, and Pontiac applications listed below.

What It Helps Solve

• Inaccurate or erratic coolant temperature gauge readings
• No gauge response from the temperature sender circuit
• Temperature warning concerns caused by a failed sender
• Replacement needs on gauge-equipped GM vehicles

Installation Notes and Tips

• Verify connector style before installation: female plug-in with blade terminals.
• Confirm the vehicle uses a gauge-based temperature sender, not a different sensor type.
• Inspect the harness connector and terminals for corrosion or looseness before installing TS-168.
• Use the vehicle service information to confirm the correct sender location and thread style.
