My name is ***** ***** I will try to assist you. first off, you are pretty dead on about the temps for the fan to kick on. These engine run at a normal operating temp of 195/200 to 135/140 degrees. The fan typically engages at 215 degrees and kicks out at 225 degrees. Sometimes the owners can set the temps higher for a better fuel savings to have the fans engage at 220 and disengage at 225. These engine run a lot hotter than their Series 60 engines at 180 degrees with the fans kicking in around 200-205 degrees. Are you certai the engine is at 220 and that the gauge itself isn't wrong? I would verify that first by checking the temp on the oil pan or radiator with a heat gun. Idle the truck up real high while it is parked and the truck should get pretty hot, pretty quick for you. Based on the info you provided me and with the gauge being a possible 3-5 degrees off (which is manufacturer expected, based on the training I got for this engine) you are within the specs for this engine for when the fan is to engage. Now if you turn the AC on, you wll get an earlier engagement for then the AC pressures come into effect which also means a cooler running engine as well. Unless you are getting a check engine light, you should be good. If you are getting the check engine light, then the parameter need to be checked and changed as well as the fan solenoid to see if there is voltage getting to it and commanding the fan on and the solenoid isn't responding properly. You will be able to see that in DDDL. It will give you tell you when the fan is commanded on and off as it is doing it, plus you can command it on and off as well. __________________________________________________________________________________________________________________________You want a 5 star service and I want to provide a 5 star service.
