Description

Replace a damaged plug at your A/C compressor or engine coolant temperature sensor with the Standard Ignition A/C Compressor Connector / Engine Coolant Temperature Sensor Connector S-550. It is a direct-fit replacement for the listed applications, including the 1983-1995 Buick LeSabre, 1985-2000 Chevrolet Astro, 1988-2000 Chevrolet C1500, 1994-1996 AM General Hummer, and 1999-2006 Chevrolet Silverado 1500 with the V8-4.8L or V8-5.3L. With 896 applications in total, see the "Vehicles it fits" section for the full list.

Two part names, one connector: S-550 is cataloged as both an A/C compressor connector and an engine coolant temperature sensor connector.
What it does: joins the component to the vehicle's wiring harness so power and signals can pass between them.
Broad coverage: listed for Acura, AM General, Buick, Cadillac, Chevrolet, GMC and more, with engines that include V6-4.3L, V8-5.0L and V8-5.7L.
Quantity: the listed applications call for one or two connectors depending on vehicle and engine. Check the "Vehicles it fits" section for your application.

Over time, a connector's housing can crack and its terminals can corrode or loosen, which may interrupt the connection. Signs this part may need replacing include an A/C compressor that won't engage or cuts in and out, or a coolant temperature reading that is erratic or missing. The sensor, compressor clutch or wiring can cause the same symptoms, so diagnose the circuit before replacing the connector.
