Water/oil Temps

Alright. Just took a roughly hour drive down the interstate and the water temp was running between 199 and 205. Occasionally dropping down to 190-194 then bouncing back up. I was parked for a little bit before heading down the interstate and the temp creeped up to 210. Its around 32-35deg here. While parked i started to notice steam coming from under the hood (it was raining and had water on the radiator as I drove to meet a friend). Checked under the hood in the fuse box when I stopped for fuel and noticed a fuse missing(or not meant to be there) called rad fan mgm* (* meaning if equipped). It's an 80amp fuse. I don't ever recall hearing the fan kick in since I've had it, but it's also been cold and short trips, etc... I tried to do some research on that fuse on what it looks like or what it controls, but I've had no success.

My oil temps in this trip were steady around 204.

Are these temps "normal"? Could I have a bad fan clutch? We had a full truck (5 people) and weren't hauling anything. Cruising 70-70mph. Truck has 185k miles on it.

Thanks

My fan rarely kicks on on a hot day hauling 12k+. On a hard pull up a hill on a summer day it will kick on above 210. It’s normalh for them to run 195-210.

Sadly, The oil temp is just a computer algorithm and means nothing in real life, I believe oil pressure is the same way:doh:

I’ve never had the fan kick on empty, Ive never looked at that specific fuse, but I can check mine if it gives you peace of mind

Hope that helps

This is what my fuse box looks like (pulled from google images). Where it's circled is where the fuse is missing (not the little green one...between the two relays), like this one is. Don't know if it's necessary or not?

Good to know... i havent hauled anything real heavy with it yet so haven't had it get super hot

You’ll know if the fan kicks on. Sounds like the fan on an N14 cummins, they have quite the hum.
I don’t know about that fuse though

Thanks bud
