Engine Coolant Temperature Sender Overview
Standard Ignition TS-85 is an engine coolant temperature sender built for vehicles that use a dashboard coolant temperature indicator light. It uses a bolt-on design with a round female plug-in connector and a single male cylindrical tube terminal for straightforward service replacement. This TS-85 sender is a direct-fit option for select Chevrolet, Cadillac, and GMC applications, including Camaro, P30, and P3500 models.
Key Features
- Engine coolant temperature sender for indicator-light applications
- Bolt-on attachment method for secure mounting
- Round female connector with plug-in connection
- Single male cylindrical tube terminal
- 3/8-18 thread size
- Factory-calibrated and tested for switch actuation at the specified temperature
- Uses a formed bimetallic contact arm for precise electrical contact movement
Product Details
Standard Ignition TS-85 is engineered for accurate temperature signaling in cooling-system warning circuits. The internal thermal design uses calibrated wax and bimetallic contact movement to transfer the electrical signal at the specified lower-temperature set point. That makes it a practical replacement when the original sender no longer triggers the coolant warning light correctly. This part cross-references FEL-PRO 35937 for the same application.

Common Problems This Part Can Address
- Coolant temperature warning light stays on or does not illuminate
- Incorrect temperature signal to the dashboard indicator circuit
- Intermittent sender operation caused by worn internal contacts
- Failed original sender on vehicles with a coolant temperature indicator light
- Service issues related to inaccurate thermal switch actuation
Installation Notes and Tips
Verify the connector style, terminal type, and 3/8-18 thread size before installation. This sender is specified for vehicles equipped with a coolant temperature indicator light, so confirm the original circuit uses a light-based warning function rather than a gauge-only setup. Clean the mounting surface and inspect the connector for corrosion before connecting the harness. Standard Ignition TS-85 is also referenced by part number TS-85 for catalog and service lookup.
Quality Assurance
Standard Ignition manufactures this sender with controlled materials, calibrated temperature settings, and production testing to confirm switch actuation at the specified temperature. As an OE ignition product manufacturer, Standard Ignition maintains quality control from component selection through finished-unit testing.
