Jeffrey 34 Posted Tuesday at 11:25 PM Author Share Posted Tuesday at 11:25 PM 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.

Joey Mack Posted Tuesday at 11:42 PM Share Posted Tuesday at 11:42 PM I would like to think it is there rear coolant sensor, but not so sure because its and ASET-CEGR.. Quote Link to comment Share on other sites More sharing options...
Jeffrey 34 Posted Tuesday at 11:51 PM Author Share Posted Tuesday at 11:51 PM 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 Tuesday at 11:54 PM Share Posted Tuesday at 11:54 PM so you have been reading the codes? are you using the cruise control to read them or a laptop? Quote Link to comment Share on other sites More sharing options...
