TO: All Chrysler-Plymouth & Dodge Dealers

SUBJECT: Customer Satisfaction Recall #348 - Coolant Temperature Sensor and Connector Replacement

MODELS: 1984 Dodge 600 and Daytona; Chrysler E-Class, New Yorker, Laser and LeBaron Passenger Cars Equipped With 2.2L EFI or 2.2L Turbocharged Engines

Coolant temperature sensors on the listed models may fail in the cold mode due to a supplier quality problem. Failure during vehicle operation will result in activation of the "Power Limited" or "Power Loss" diagnostic signal light, but should not significantly affect engine performance. However, after the ignition switch has been turned to the "off" position, a warm engine may not restart. To avoid this problem, the coolant temperature sensor on each involved vehicle must be replaced. An improved connector which recently entered production will also be installed on those involved vehicles which do not already have it.. Both parts have been revised for improved durability. In addition, a quick-disconnect is provided in one lead of the new connector. This is to be used when setting engine idle speed or timing, instead of disconnecting at the sensor.

Information to assist in completion of the recall service is detailed in the following sections.
