Standard Ignition TS-315 Engine Coolant Temperature Sender

Engine Coolant Temperature Sender Overview

The Standard Ignition TS-315 engine coolant temperature sender is built for accurate thermal switching in cooling system applications. It uses a formed bimetal contact arm and factory-calibrated actuation points to deliver consistent electrical signaling for fan control and related engine management needs.

For drivers and technicians servicing a Chevrolet, Ford, or similar vehicle application, the TS-315 provides a direct-fit style solution with a bolt-on connector design and a single male round connector interface.

Key Features

• Engine coolant temperature sender for cooling system electrical control
• Bolt-on attachment method for secure mounting
• Single male round connector for straightforward electrical connection
• Single male screw terminal design
• Factory-calibrated switch actuation at the specified temperature set point
• Bimetallic contact arm design for precise thermal response
• Standard Ignition TS-315 construction with quality-controlled manufacturing

Detailed Product Description

The Standard Ignition TS-315 is engineered as an engine coolant temperature sender that responds to heat changes in the cooling system and transfers the electrical signal to the fan controller. Its thermal switching design uses custom wax formulations and a bimetal contact mechanism to create repeatable actuation at the intended temperature range. That makes it a practical choice when replacing a worn coolant temperature sender on a Chevrolet or Ford cooling system service job.

Standard Ignition calibrates and tests each unit during production to confirm switch operation at the specified lower-temperature set point. The TS-315 is designed for service professionals who need consistent electrical performance, stable temperature response, and OE-style manufacturing control in a cooling system sender.

This part cross-references Four Seasons 37446 for the same application.

Common Problems This Part Can Address

• Cooling fan not switching on at the correct temperature
• Erratic temperature signal to the fan controller
• Intermittent coolant temperature sender operation
• Overheating concerns caused by delayed fan activation
• Faulty thermal switch response in the cooling circuit

Installation Notes and Tips

Verify connector style, terminal layout, and mounting style before installation. The TS-315 uses a bolt-on attachment method, a male round connector, and a male screw terminal, so matching the electrical and physical interface is important for proper fitment. Inspect the cooling system connector and wiring for corrosion or damage before installing the new sender.

For best results, confirm the replacement part number TS-315 against the original unit and compare the temperature switch specification to the vehicle’s cooling fan control requirements. This helps ensure proper operation in the intended Chevrolet, Ford, or other listed application.

Quality Assurance

Standard Ignition manufactures this sender with complete quality control from component selection through finished product testing. Each unit is calibrated and tested to confirm actuation at its specified temperature, supporting consistent performance in cooling system service.
