Fan Cycle

[athens]

I'm having the same issue. All my other issues have cleared up, but fan stays on while driving. Does anyone have pictures on where the AC pressure switch is located.

I have a 2011 ISX15 cm2250. I was provided with steps to check air passing thourgh the clutch fan. Air flowing and no leaks. I am checking all the recommendation listed.

Two things. One, the fan clutch could be stuck. Mine does this after sitting a few days. I have to build up full air pressure then shut off the truck. Then turn the key on to energize the solenoid to release the fan clutch. Then I smack it with a hammer a few times to free the clutch media from the hub. Works fine for the next month till I go home. Second, if it's a prostar the a/c high pressure switch is on top of the charge air cooler where the a/c lines cross over.

My fan is on and happy running since last nite from Dallas to Indy that I just delivered and head home....mine is due to a air leak that I can hear but cannot find yet on the hub area

Not fan to have that fan ..lol... running when temp are 16-23 F ...had to cover the nose altogether...
Ordered a rebuild kit ...see if I can do it....I have the HD Borg Warner....anybody did it????

Btwy ,this shows how poor the parts are made...truck and hub fan assy have 3.5 y 342k miles since they were put together....
On a Volvo 1999 with S60 Detroit did rebuilt it at over 1mil miles
