Standard Ignition TS-159 Engine Oil Temperature Switch

Engine Oil Temperature Switch for Corvette

Standard Ignition TS-159 is an engine oil temperature switch built for precise electrical actuation in temperature-controlled engine systems. It uses a formed bimetal contact arm and factory-calibrated thermal switching to deliver consistent signal transfer for the fan controller on select Chevrolet Corvette applications.

Key Features

• Male connector with plug-in design for straightforward electrical connection
• 1 blade terminal for a direct signal interface
• Factory-calibrated actuation point for consistent temperature response
• Bimetallic contact arm design for precise creep-action switching
• Custom wax-based thermal element formulated for the specified temperature range
• Built with high-grade materials for service-professional use

Detailed Description

Standard Ignition TS-159 is engineered as an engine oil temperature switch for temperature-sensitive control circuits. The internal thermal element expands when heated, moving the snap-action contact to send the electrical signal to the fan controller. This design supports accurate switching at the specified lower-temperature set point and is calibrated during production to confirm proper actuation. Compatible With 1981-1982 Chevrolet Corvette and 1984-1989 Chevrolet Corvette applications, TS-159 is a direct-fit service part for vehicles that use a male, plug-in, single-blade terminal connection. This part cross-references Standard Ignition TS-159 for the same application.

What It Helps Address

• Inconsistent fan controller signal due to a worn thermal switch
• Delayed electrical actuation at the specified temperature point
• Intermittent temperature-based switching in the oil temperature circuit
• Connector mismatch when replacing the original plug-in, blade-terminal switch
• Service replacement needs on Chevrolet Corvette temperature control systems

Installation Notes and Tips

Verify connector style, terminal count, and thread/application match before installation. Inspect the harness plug and terminal condition, then confirm the replacement switch is seated and tightened to the vehicle specification. After installation, test system operation to confirm the fan controller receives the correct signal at the intended temperature.

Quality Assurance

Standard Ignition manufactures this switch with controlled component selection, factory calibration, and end-of-line testing to confirm actuation at the specified temperature. As an OE-focused ignition and electrical manufacturer, Standard Ignition maintains quality control from component production through finished assembly.
