started truck up one morning this past week and check engine light came on........................ if it is idling doesnt make noise but when i press the fuel pedal it kinda makes this weird noise and its coming from the fan area...................if i turn the fan switch on, the check engine light goes off???? any ideas before i take it to detroit diesel?? i took it to TA, flash codes were 46(ecm) and 62(aux power)..i may need new batteries, mind you both of those codes were already there b4 this problem
yeah coolant level is good........... its at normal level, im gonna take it to detroit diesel next week and just wanted to see if maybe some1 knew........ someone told me the clutch bearing or something????
I don't know if Freightliner uses Horton fan clutches. You have an EGR engine, right? Find out if they use Horton and if so get to the dealer before anything else :shock:
