My 2008 f-250 has a problem with the cooling fan, it turns on every 4-5 minutes after its warmed up
What could it be?
Sounds normal to me. They have a set temperature that they turn on and off at, so in he summer they will turn on more than in the winter, just make sure your coolant level is at specs cold engine.
