Detailed Product Overview

This engine coolant temperature sender uses a thermal switching design that relies on controlled metal expansion to trigger the electrical signal at the specified lower-temperature set point. Standard Ignition manufactures the TS-145 with calibrated and tested switching performance, using high-grade materials and controlled production processes to maintain consistent operation. It is a direct-fit service part for vehicles equipped with a coolant temperature indicator light rather than a gauge-style sender.

This part cross-references Four Seasons 37927 and 85221 for the same application. Common fitment searches include 1982-1986 Chevrolet S10 coolant temperature sender, 1982-1986 GMC S15 temperature sender, and 1982-1986 Pontiac 6000 coolant light sender.

What It Helps Address

• Inoperative coolant temperature warning light
• Erratic or delayed dashboard temperature light activation
• Failed thermal sender causing inaccurate warning signals
• Service replacement for worn or corroded sender connections
• Restoration of factory-style coolant light operation on listed vehicles

Installation Notes and Tips

Verify the connector style, terminal count, and thread size before installation. This TS-145 uses a male connector with one blade terminal and a 3/8-18 NPT dryseal thread, so matching the original sender configuration is important for proper fit. Confirm the vehicle is equipped with a coolant temperature indicator light on the dashboard, since this sender is not listed for gauge-style temperature systems.
