Please check notes in each part listing to ensure the Coolant Temperature Sensor Connector is correct for your 2000 PONTIAC SUNFIRE with a 2.2L engine. STANDARD MOTOR PRODUCTS, AIRTEX / WELLS, & ACDELCO are competing brands, and each brand's Coolant Temperature Sensor Connector may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Coolant Temperature Sensor Connector fits only certain 2000 PONTIAC SUNFIRE models.
