Standard Ignition Engine Coolant Temperature Sender P/N:TS-521
Keep your dashboard temperature warning light tied to real engine coolant conditions with this Standard Ignition switch, the TS-425 Engine Coolant Temperature Sender. It is a direct-fit replacement for the 1986-1990 Toyota Tercel and the 1991-1992 Toyota Corolla. See the Buyer's Guide tab for engine details.
Standard Ignition lists the TS-425 as a temperature sender with light. It is a switch-type sender that works with the temperature warning light circuit. It is designed to switch that circuit when engine coolant reaches its specified temperature.
Signs this part may need replacing: a temperature warning light that stays on with a cold engine, a light that never comes on when it should, or coolant seeping around the sender body. Wiring faults and other cooling-system problems can cause similar symptoms, so diagnose the cause before replacing the sender.
