Standard Ignition TS-82 Engine Cooling Fan Switch

Engine Cooling Fan Switch for OE-Style Temperature Control

Standard Ignition TS-82 is an engine cooling fan switch built for precise fan activation in temperature-sensitive cooling systems. It is a direct-fit service part for select Chevrolet Camaro, Corvette, and Pontiac Firebird applications, along with other listed vehicles that use a single-terminal, female bullet connection.

Key Features

• Female connector gender for the specified vehicle harness connection
• 1 terminal with bullet-style terminal type
• Factory-calibrated switch actuation at the specified temperature set point
• Wax-pellet and bimetallic contact design for controlled electrical switching
• Calibrated and tested during production for consistent operation
• Built with high-grade materials for service replacement use

Detailed Description

The Standard Ignition TS-82 engine cooling fan switch uses a thermal design that responds to coolant temperature and signals the fan controller when the set point is reached. Standard Ignition forms and calibrates each switch to meet its specified actuation temperature, helping maintain proper fan operation in vehicles that rely on thermal switching for cooling control. This part cross-references Airtex Fuel Pumps FS111 for the same application.

Fits 1985-1991 Chevrolet Corvette, N/A; fits 1986-1992 Chevrolet Camaro, N/A; and fits 1987 Pontiac Firebird, N/A in the listed configurations. It also fits 1991-1992 Pontiac Firebird, N/A, including vehicles equipped with Canada Emissions where noted.

Common Problems This Part Can Address

• Cooling fan not switching on at the correct temperature
• Fan cycling inconsistently due to a worn thermal switch
• Overheating caused by delayed fan activation
• Cooling system warning signs tied to inaccurate temperature signaling
• Electrical contact issues at the fan switch connection

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. Confirm the cooling fan system uses a single-terminal switch with a female bullet connection, and match the replacement to the original temperature specification. For best results, inspect the harness connector and surrounding cooling system components during service.

Quality Assurance

Standard Ignition manufactures this switch with factory calibration and testing to confirm actuation at the specified temperature. The design and production process are controlled from component selection through finished product inspection to support consistent thermal switching performance.
