Jeffrey 34 Posted October 15 Author Share Posted October 15 I’m having problems with engine fan on this 2006 Mack vision ,when pulling a load and temp gets close 200 the fan kicks on and the temp goes down to 150 and the fan never cuts off until I stop and switch truck off and start again,it’s like a sensor or something not sending signal to cut fan off ,any suggestions would be appreciated.

Jeffrey 34 Posted October 15 Author Share Posted October 15 Going to replace coolant sensor and see if that helps ,when fan kicks on the lightning bolt comes on and codes for fan clutch blinks ,fan is not 3 months old.

Joey Mack Posted October 15 Share Posted October 15 so you have been reading the codes? are you using the cruise control to read them or a laptop?
