Detailed Description

This connector is used where the engine management system needs a reliable coolant temperature signal. On modern systems, that feedback helps the ECM manage A/C operation; on earlier vehicles, the circuit can directly control compressor shutoff to help prevent compressor failure. If the original connector is cracked, heat-damaged, corroded, or loose, replacing it can restore a stable electrical path between the sensor and the harness. Fits 1991-1992 Chrysler Grand Voyager, N/A; Fits 1990-1992 Chrysler Town & Country, N/A; Fits 1986-1992 Dodge Caravan, N/A; Fits 1987-1992 Dodge Grand Caravan, N/A; Fits 1986-1992 Plymouth Voyager, N/A; Fits 1988-1989 Buick Reatta, N/A.

Common Problems This Part Can Address

• Broken or brittle coolant sensor connector housing
• Corroded terminals causing poor sensor communication
• Intermittent A/C compressor control caused by signal loss
• Hard starting or drivability issues tied to inaccurate coolant temperature input
• Heat-damaged pigtail wiring near the sensor

Installation Notes and Tips

Inspect the sensor side and harness side before installation to confirm terminal style, wire condition, and connector indexing. Match the 2-terminal configuration to the original connector and verify the repair against the vehicle’s existing coolant temperature sensor pigtail. For best results, repair any damaged wiring before final connection and confirm a tight, fully seated fit after installation. Compatible vehicle coverage includes Chrysler Grand Voyager, Dodge Caravan, and Plymouth Voyager applications, along with many older GM and Jeep platforms listed in the fitment data.
