Detailed Description

Standard Ignition TS-93 is an engine cooling fan switch used to control fan operation based on coolant temperature in select Toyota Corolla, Celica, MR2, Tercel, Camry, and Lexus LS400 applications. The switch uses a rectangular connector, male blade terminals, and a toggle-style actuation design to support direct replacement service where the original cooling fan switch has the same thread and terminal configuration. This part cross-references Airtex Fuel Pumps FS190 for the same application.

Compatible With 1990-1994 Lexus LS400, N/A; 1993 Toyota Corolla, N/A; 1991-1992 Toyota Celica, N/A; 1989-1992 Toyota Corolla, N/A; 1992 Toyota MR2, N/A; 1991 Toyota MR2, N/A; 1985-1989 Toyota MR2, N/A; 1990 Toyota Celica, N/A; 1988-1989 Toyota Celica, N/A; 1983-1988 Toyota Tercel, N/A; 1984-1986 Toyota Camry, N/A; 1984-1985 Toyota Corolla, N/A; and 1980-1982 Toyota Tercel, N/A.

What It Helps Fix

• Cooling fan that does not switch on at the proper temperature
• Fan operation that stays on longer than expected
• Overheating caused by a failed radiator or engine-mounted fan switch
• Intermittent fan control from worn electrical contacts
• Temperature-based fan response issues on Toyota Corolla, Celica, MR2, Tercel, Camry, and Lexus LS400 models

Installation Notes and Tips

Verify the thread size, connector shape, terminal count, and mounting location before installation. This TS-93 uses a plug-in connection with 2 blade terminals and no wiring harness, bulb, or mounting bracket included. Confirm whether the vehicle uses a radiator-mounted or engine-mounted switch, and match the application notes for Toyota Corolla, Celica, MR2, Tercel, Camry, or Lexus LS400 before replacement.
