Have Truck Repair Questions? Ask an Expert
Welcome to Just Answer. My name is ***** ***** I can help you today.
I was hoping you can clarify a few things first:
What is the temperature that the fan kicks on at? Typically the fan would engage between 215 and 225 and bring it down to 185-195.
Is the unit actually overheating in certain pull, or situations?
Any codes coming up?
Any information helps, thank you!
Have you noticed whether this unit can do a Regen, does the regen happen when it's overheating like this at all? I just want to be clear what generation of emissions this motor has.
When it overheats is the fan still working to try and cool the unit? it just can't keep up with the overheat? When it heats up is it only when your fully loaded, or all the time?
My first suggestion would be to engage the clutch fan, even if you need to do it manually. Then try and pull on the clutch to see if its totally solid with the fan hub when engaged, or is it slipping. If it seems like its slipping at all, or if there is no clutch padding left I would recommend replacing the fan clutch.
A lot of the time its not a matter of when it engages and more a question of whether the unit can keep up with the engine heat. If the fan is slipping then it will not be able to spin fast enough to cool.
Good Day, I wanted to follow up on your fan repair to see if you have had any success in the diagnosis? The question will remain open for several days but will eventually time out. I want to invite you back for any follow up questions you may have. Otherwise, a rating of my services is greatly appreciated!
Hello Sir, Were you able to take a look at the fan clutch at all on your truck? I wanted to check in because the question is still open, but will time out unless you respond. I am here for any follow up questions at all since you have already paid for the service. Otherwise, a rating is greatly appreciated because if you don't the site keeps the proceeds instead of the expert.
Thanks again and await your response, have a good day!
