Report: Corrosion at Coolant Temperature Sensor
Dodge Shadow Problem
4 Cylinder engines, with a hard starting condition when cold and illumination of the Check Engine Light may have corrosion build up on the engine coolant temperature sensor. Our technicians tell us that the coolant sensor and pigtail should be replaced to correct this issue.
