How to Determine if a Truck Fan Clutch is Faulty?
1 Answers
Truck fan clutch failure can be determined by checking for oil leaks and observing changes in water temperature during winter or summer driving. Specific details are as follows: 1. Water temperature changes: A faulty fan clutch can cause excessive or insufficient airflow. Excessive airflow prevents the engine temperature from rising promptly, while insufficient airflow leads to engine overheating and operational failure. 2. When the fan clutch malfunctions: In this scenario, the engine may fail. The main shaft of the loosened nut locking disc inserts into the pin hole, fixing the fan and drive shaft without using the fan clutch, forcing the fan to rotate. When there's an opportunity to repair the fan clutch, the automatic clutch function should be restored.
