What is the issue if the Cadillac fan keeps running non-stop?
1 Answers
Cadillac fan keeps running non-stop due to excessively high engine coolant temperature or a short circuit in the fan circuit. Below are specific details about the car's cooling fan: 1. Automatic activation conditions: The radiator fan automatically turns on when the coolant temperature reaches 98°C. The car radiator fan activates automatically and cannot be manually controlled. It does not start at low temperatures, and operates at two speed levels for medium and high temperatures. 2. Medium and high-speed cooling fan: Generally, the medium speed automatically activates at 95°C, and the high speed activates at 105°C. When the coolant temperature reaches 95°C, the fan starts and runs at 1600 RPM. When the temperature reaches 105°C, the fan speed increases to approximately 2400 RPM to enhance the cooling rate.
