E350 5.4 liter water temp

So reading rgnprof's post about running hotter got me wondering. I have scan gauge and I would say my "normal" temp is 200-202 when cruising at say 60-62. Is this an okay temp? I am in Florida so it's hot most of the time. If we are towing it does run a little hotter on climbs like an overpass or hill, but will come back down shortly after. E350 5.4L with 45,000 miles. 2011 Fleetwood Tioga Montara 23B weighs about 10-12,000 depending on wether we are on vacation or not.

Thanks Marty
  • Considering that your engines thermostat is 195*, that would be in the correct range.. Time to start seeing things happen is when it gets over 240^ or so..

    Good luck!
