Keep watch over engine temperature with this Standard Ignition switch: the TS-25 Engine Coolant Temperature Sender, built for applications that use a dash temperature warning light. It is a direct-fit replacement for many vehicles, among them the 1969-1970 Chevrolet Camaro and 1974-1975 GMC Jimmy. See the "Vehicles it fits" section for the full list of applications and engine details.
The sender reads engine coolant temperature and switches its circuit at a calibrated set point. It is designed to trigger the temperature warning light when the engine reaches that temperature.
- In-house quality control: Standard Ignition is a global manufacturer of original equipment ignition products. It controls quality through the entire manufacturing process, from componentry to the finished product.
- Calibrated and tested: Every unit is calibrated and tested to confirm the switch actuates at its specified temperature.
- Factory-set contact point: Each thermal switch is factory-calibrated to make electrical contact at its specified set point.
- Robust design: High-grade materials and a robust design are chosen to meet the demands of today's service professional.
These are signs this sender may need replacing: a warning light that stays on with a cool engine, a light that never comes on as the engine heats up, or coolant seeping around the sender. If a failed sender is the cause, this unit replaces it. Also check the wiring and the cooling system, because faults there can produce similar symptoms.
