Keep your dash temperature reading honest with the Standard Ignition Engine Coolant Temperature Sender TS-569. It installs as a direct-fit replacement for the listed classic GM applications, including the 1968 Buick Skylark, 1968-1969 Buick Special, 1968-1969 Chevrolet Corvair, 1975-1976 Chevrolet G10, 1975-1976 Chevrolet G20, 1976 Chevrolet G30, 1969 Chevrolet Nova, 1975 Chevrolet P20, 1975 Chevrolet P30, 1975 GMC P25, and 1975 GMC P35.
- What it does: Reads engine coolant temperature and sends a corresponding signal to the dashboard temperature gauge.
- Direct fit: Designed to install in the engine's coolant temperature port on the listed applications.
- Signs it may need replacing: A gauge that reads erratically, sticks, or shows an inaccurate temperature can point to a worn sender — diagnose the cause before replacing.
If a failed sender is the cause of a misbehaving temperature gauge, this unit replaces it. Because a bad reading can also stem from wiring, the gauge, or an actual cooling issue, confirm the sender is at fault before installing.
